Many RVs and camper trailers use a power converter to operate the lights, refrigerator, vent fans, and perhaps the thermostat on the heating system. The converter uses the 110-volt AC power from the local power source and transforms it into the 12-volt DC these items require.

This article is intended to help you troubleshoot many converter problems and to repair or replace the unit if need be. Since there are different makes, types, and sizes of converters, this article will deal with problems common to most models.

Although electrical knowledge is helpful, it is not necessary in order to be able to check the power converter or to repair or replace it.

For more basic information on how the electrical system on your RV works, see this article.

Safety Alert!

Always unplug the RV from the 110-volt power supply before attempting to repair any electrical components of the power converter unit.

Types of Converter Problems

In most cases, a malfunctioning converter will just cease to function with the result being the total loss of power to any 12-volt DC fixtures or controls. In other cases, the converter will produce power, but not enough to run the 12-volt DC electrical system.

But until the onboard 12-volt batteries are exhausted of their charge, the problems will not become apparent. The power converter is supposed to maintain a constant charge on these batteries, supplying variable voltage depending on the amount being drawn from the 12-volt DC system.

Remember that the onboard batteries must be in good shape and able to hold a full charge. One bad battery will draw power from the other good batteries and will eventually cause them to fail also.

To check the batteries, it is necessary to fully charge them and then disconnect them from the others to check their recharging abilities. Check them with a multimeter, after they sit awhile, to determine if one or more is losing voltage.

Troubleshooting the RV Power Converter

The first step in determining the problem is to start from the beginning—that is, the point where the 110-volt AC supply enters the RV power converter.

  • With the RV power supply connected, check the voltage at the point it enters the converter. It should be between 108 to 130 volts. Anything in this range is okay!
  • The next order of business is to check the voltage where it connects to the 12 volt DC breaker box. It should be 11-13 volts to operate satisfactorily. Anything less indicates a bad power converter.

Once we know the problem is a malfunctioning RV power converter, we can check the inner components of the unit.

1. Power Converter Fan

RV power converters use a small fan to keep the electrical components cool while the unit is charging. It should be possible to hear the cooling fan running intermittently while the converter is in use (the fan may operate only when the temperature reaches a certain point).

This fan normally uses the 110-volt AC line voltage to operate. If the voltage to the fan is in the correct range, the fan itself is probably malfunctioning. Replacing this fan is normally an easy project, but finding the right fan might be a problem. Note the make, part numbers, voltage, and any other information on the RV power converter fan motor, for use in obtaining a replacement online.

In some cases, a different make and model may be substituted as long as the voltage and amperage are similar and the motor fits in the space. If the voltage is not getting to the cooling fan from the thermostat, a replacement thermostat is needed. These can be found online as well.

A thermal sensor is used to switch the cooling fan on and off, depending on the operating temperature of the converter components. Make sure the current is getting past this sensor and to the cooling fan before buying a new fan.

If the fan itself, as opposed to the sensor, is not malfunctioning, you should be able to jump the sensor and cause the fan to operate. If this is the case, replace the sensor with one of equal temperature rating.

2. Resistors and Circuit Board

Some power converters rely on a resistor to control the voltage to the onboard batteries and the 12-volt DC system. In some models, the resistor is riveted to the converter box. When checked with the multimeter, the resistor should read from 3 to 13 volts, depending on the present charge of the battery, and which onboard 12-volt lights, fans, and other accessories are being used. If your batteries are not being fully charged, the resistor is often the culprit.

It may be necessary to disassemble the converter box to access this resistor. Be careful if the circuit board requires removal, or you may damage it. Drill out the rivet and replace with the correct replacement resistor.

If the exact replacement part is difficult to locate, you may find a satisfactory replacement at an auto supply store because this type of resistor is used in many automotive applications. As long as the values are the same, almost any 12-volt DC resistor should work. Once this resistor is replaced, the onboard batteries should stay charged with the proper amount of voltage.

3. Replacement

Sometimes it’s just better to bite the bullet and buy a new converter, especially if you aren’t the DIY type of person or just don’t have the time to chase down parts. But actually, it isn’t all that costly to install a new power converter. Installation is very easy too.

Progressive Dynamics Inteli-Power converters are fan-cooled and deliver clean, dependable 12-volt DC power to the lights and other appliances in your motorhome or camping trailer. Choose from 45-, 60-, and 80-amp models to fit your particular RV power requirements.

If you’re thinking of replacing the 12-volt DC breaker panel, or updating an older motorhome or travel trailer, the Parallax 7345 Power Center combines the power converter with a reliable breaker system for dependable, clean 12-volt DC power to supply your RV. (For more on breaker systems in RVs, see this article). Parallax also provides 45- and 55- amp converters and breaker panels separately.

A good 12-volt converter system can make or break a camping trip. Learning to repair and understand how the system works will eventually pay off on one of these occasions. Good luck!

      Bobbi, there are also breakers/fuses for the 110 volt circuits besides the ones on the converter powering the 12 volt circuits.

      I will have to check that. Didn't know about it. I checked the breakers which are in front of the converter. Are there other breakers somewhere else?

      I am new to all of this. Still and always a learning curve.

      Thank you so much.

      Bobbi, have you checked the main 2 volt ground yet? It's end of the negative battery cable where it attaches to the steel frame of the camper. It's common for this connection to corrode or get loose. Even if t appears claean and tight it bears checking.

      Have you checked the breakers in the 12 volt power panel for the lights and fridge yet? Besure to check the breaker side going to the lights and fridge, not the already hot side.

      Randy.

      I have a 2003 Keystone Everest. I have had a for about 3 years now and had no problems with it until last July. The converter blew and I had it and the battery replaced. Over the holiday weekend the battery died (I don't think the converter is charging the battery) so my overhead lights and fridge died too. Now that I have the battery recharged, and checked the fuses and breakers and GFI, I still have no power to my overhead lights or the fridge. Need to know what else to do or check.

      My converter was replaced with a powermax 110 volt to 12 volt dc

      bhinmi, Check the negative battery cable end where it is connected to the steel frame of the camper. This is the main ground for the 12 volt system. This connection should be clean and tight or otherwise weird things can happen.

      Also check for an inline breaker or fuse on the positive wire going back to the converter. Not all campers have this fuse/breaker but yours may.

      If this isn't the problem try connecting a good battery charger--at least 20 amps--to the batteries and if things operate normally then a new converter may be in your future.

      I have a 97 GB Cruise Air. My 120v works everything on the coach but when I unplug there is no DC coming from house. House is also not charging. Panel doesn't work, water pump or lights don't work on DC. I can't find an inline fuse between the House and the low voltage distribution panel. I have a PD9260C converter. Not sure if the "Switch" is inside the converter or not. Debating on whether or not to replace converter. All fuses are good. Replaced batteries and wired them parallel 12v so that is not problem. Pulling hair out!

      Jackie, You need to check the the main ground for the 12 volt system first. This is the negative battery cable end which attaches to the steel frame of the camper.

      If this connection is corroded or loose, it will cause all sorts of strange problems with the 12 volt DC system. Even if the connection appears tight and clean, that doesn't mean it's good ground. Clean it well.

      Let me know if this doesn't help and we'll go from there.

Now all is off..I then unplug the camper wire open the powerconvertor box.ck fuses none broken. Pulled out the breakers. Called around to find the 30/20 15 and 15.. They said we have a universal one

      I got it but it doesnt fit. Took them back i need to replace the ones in there. They are orginal 2004 parallax 7300 series. breakers.cant find them. Not sure if tjats even the problem. I am a 67 yr old woman disabled living full time in it. I have very little income to hire this done.what do you think..i have kept the hot water off. Only used the AC one week. This summer. Tell what i need to do and steps please

      13 volts. When we were on the road camping (2 weeks ago) the battery was as low as 8 volts. I was having to take a battery from my truck engine to open or close the slides. No fun!! While we have been preparing to put trailer in storage I've tried different things. I was shocked when the battery went to 13 volts. I don't know what else to try before replacing the unit.

      Following up with better info. My trailer is a 2010 Montana Mountaineer. Unit is connected t0 30A service. I have a WF-9865 series converter. The best output I get is 13A. My craftsman (82180) does not do dismals.

      Output is 13A from converter.

      With no battery connected, the best I get is very dim 12v lights. Ground wires all appear tight, With battery connected lights look bright. I'm ready to replace it. I have not heard a fan, but I don't know if it has needed it. ??

      Randy,

      I have a 2005 Winnebago Vectra MH, with a Dimensions StandbyPower System 2000w inverter, charger, fast transfer. On a month long trip, a few weeks ago while hooked up to 50amp shore power, I lost electrical power. I first noticed a low dc power indicator on frig, it shut down, then within 30 minutes, no power to whole home. Batteries were down to 11.5 volts, finally down to 10.5. My 50amp cord was hot for 6-8 ft from the post. A local tech suggested cutting cord off to "bad" part, which I did. Replaced old batteries and hooked up again. Started losing power again, so he thought inverter was bad. Once we returned home, local RV repair went through system, charged me $550 for labor & replacing an outlet plug. Said inverter was fine. Within 2 days, my batteries were again being drained, and frig gave low dc warning. Seems repeat of same problem. RV repair shop can't get it in for another week, but I don't have faith they'll find what's wrong, without charging me more labor charges for "searching"again! Is there any light you can shine on my issue? Does inverter need replaced?

      Hi Frank, check the battery negative cable where it attaches to the steel frame of the camper. If this connection is loose or corroded--even if it doesn't appear to be--it will prevent the converter from properly charging the battery.

      Hi Randy,

      I have a 2006 Escalade by K-Z. Everything is working properly but when I I'm plugging into 120ac and use the 12v dc lights the battery discharge rapidly... I was under the impression that the converter was suppose to maintain the charge in the battery while using 12v dc when plugged in 102ac.

      I changed my converter and I have 13.66v there. After running the on 12v dc light that is drawing about 7amp for about half hour. The battery read less than 12v. If I use the lights more the battery is discharged in about a day.

      It's just plugged in and sitting in driveway and am not using anything in the 12V circuit other than the vapor detector. I'll go out there one time and test the circuit by turning on a light, and it doesn't come on. Another time it will. Then occasionally I'll hear vapor detector cycling on/off, as if the entire circuit is opening and closing. Trying one of the lights during this event and it flickers on/off. No rhyme or reason. All the other non-12V items are unaffected.

      Susan, the converter is normally near, or sometimes, part of the 12 volt DC power panel. Be sure ad be sure the main 12 volt DC ground is clean and tight. This is usually the negative battery cable end where it attaches to the steel frame of the camper.

      If this doesn't help, then turn off the converter breaker and connect at least a 20 amp charger to the batteries. If this solves the problem, then a new converter is probably in your future.

      Craig, do you mean the shore connection? If so, you may need to check the battery negative cable end where it attaches to the frame of the camper as this is the main ground for the 12 volt system.

      It may also be a bad converter. Try connecting a good battery charger and see if that makes a difference.

      My converter is only putting out 7.6 volts dc. Does my WFCO 8935 have a separate panel and converter or is it one part. I think it is only converting one side of the AC. Your thoughts please.

      Rob, check the battery negative cable end where it attaches to the steel frame of the camper. This is the main ground for the 12 volt system and if it isn't clean and tight all sorts of weir electrical problems may happen. Let me know if this doesn't help.

      fboot, try turning the converter breaker off and connecting a good charger to the batteries. See if the clicking stops and the lights work properly. If so, a new converter may be in your near future.

      Hi. My RV fridge seemed to be making unusual click noises. (But it could be the Power Converter underneath it.) (the click is not from the pilot ignighter) My RV lights HUM. I turn diff ones on/off until it stops.

      Last night the click noises wouldn’t stop unless I left a light on.

      What should I do? Some say Converter HUM will come and go.

      I’m concerned about that other repetitive click.

      Joy, yes just be sure to check it occasionally to be sure it doesn't overcharge.

      While waiting on my new power converter to arrive can I leave the battery charger on the battery so everything will work. Or will it over charge things

      Jim, check the negative battery cable end where it attaches to the steel frame of the camper. Make sure this connection is clean and tight, otherwise the batteries won't operate the lights and other 12 volt dc items properly.

      I have a 1992 5th wheel and when i unplug the 120 it doesn't switch to 12v, is there a seitch to change over or is it suppose to do that automatically, there is a tag that says the inverter has been retrofitted

      Susan, is the 12 volt system not working or is it the 12 and 120 volt altogether?

      My pop up trailer power shut off suddenly on my last camping trip. The main power cord looked a little burnt so I replaced the male main plug and there is still no power. The fuses are all good and I put the main breaker on and off, where should I look next?

      Codabird, first check the battery cable end where it connects to the steel frame of the camper. This is main grond point for the 12 volt system. If this connection is clean and tight, then connect a good battery charger and turn off the converter breaker.

      If this gets your 12 volt system working, then a new converter is needed.

      Andy, Connect a good battery charger and trun the converter breaker off. If everything works normally then the converter is probably bad.

      The other day my 2013 Salem Hemisphere lost power to fridge radio, tv, microwave,etc.. about half the trailer was not working. Found a loose wire on battery. Hooked it up and everything working again. Then battery died after 2 days.Replaced the battery. The new battery lasted 4 days and then died. I charged the battery and hooked it back up. As soon as I touched the wire to the battery terminal the fan on the converter comes on for about three seconds and then stops. Seems it never comes on again. Is the converter not charging my battery??

      Bill, try turning off the converter breaker/fuse and connecting at least a 20 amp charger to the batteries. If the fridge and everything work normally, then need a new converter.

      Recently our fridge started crapping out, and coincident, the power supply fan started coming on more often. The 12V lights work fine. The fridge starts up okay, generates cooling for a while, and then goes into fault. Battery is nearly new. Is it possible the converter is pushing like barely 11 volts, the lights don't care but the fridge can't cope?

      Chrissy, check the battery, negative cable end where it connects to the steel frame of the camper. If this connection is loose or corroded, then all sorts of weird problems may occur.

      If you check the connection and still have the issue, then feel free to let me know and we'll try something else.

      We have a 2003 wanderer light hybrid, on a recent camping trip the lights were dim and flickered a bit. We began changing out lift fixtures. First light all was well and nice and bright, second light was good but moving from main living/kitchen area of coach to bathroom we lost lights to 1/2 of the coach the first light and front part of trailer works fine as do the tank gauges. The hot water heater will not turn on at the switch. Refrigerator works as well. There is 120 come from converter and 12 volts at the fuse box (all fuses are good) hoping for good news and not the doom of a costly rewiring fix???

      Allen, check the negative battery cable end where it connects to the steel frame of the camper. A loose or corroded connection will cause all sorts of strange problems with the 12 volt DC system.

      Let me know if this doesn't solve the problem.

      Hello, I need help....

      I think I have a bad converter but not real sure. I tested a few things but the outcome did not make sense. The converter is an elixer-25. It's my daughters pop-up she just purchased used. Everything was working(AC&DC) until I took the battery out and gave it a good charge. When I hooked the battery back to the camper the DC lights would not come on. Nothing with DC current works. She is plug into shore power and the air conditioning and everything else on the AC circuits work but no lights. After checking all the fuses, ground connections, etc, I decided to start looking at the converter itself. The red wire coming out the back of the converter is connected with a wire nut to the positive battery lead. I stuck my voltmeter into the wire nut connection and no power or 0 volts. I took off the wire nut and pulled the red wires apart. I checked the voltage from the battery lead and it is around 13v. I connected the battery lead and converter positive lead back together and the voltage was back to 0. I disconnected the battery lead and converter positive lead back apart then took my battery charger and connected it directly to the ground and positive lead on the converter and low and behold all the DC circuits began to work whether I was plugged into shore power or not. I do not understand why I would have 0 volts when I connect the battery lead to the positive converter lead but when I disconnect the leads I get 13v on the battery lead and 0 volts on the positive converter lead. Thanks for any help

      Ced, if the GFIC is showing a bad connection, I suspect a bad ground somewhere. I'm reluctant to advise you if the camper is still under warranty.

      Kenneth, normal voltage from the converter will be 13+ volts DC. If the converter is working you are getting voltage to the converter breaker in some manner as it operates on 110-120 volts.

      Can you explain a bit more

      Having problems with my power to my 2006 Everest 5th wheel. I have power coming in from my main breaker box which is a 30amp. I have a 50 to 30 cord and know not to use both ac's at the same time. I am just wanting to get the feel of how it all operates since i just purchased. Anyway no power to main breaker in the camper so i replaced the converter. My batteries are showing more than 12 volts and the line from the converter to the main panel are at 12v. Im still not getting power to main breaker

      Michael, yes the converter you mentioned will be fine. All converters have overcharge protection to prevent an issue but your old converter may had a bad circuit and failed to prevent overcharging the batteries.

      So I’m unclear with your answer. Will the larger converter work better and would you go with the features of the one i listed so the batteries don’t over charge and boile away.

      Michael, the converter also controls the thermostat in the AC if you have a wall mount stat. The new converter should do the trick.

      Randy Thank you. i researched on line after leaving you the message and the converter i have is a WFCO 75 AMP MODEL NO WF 9875. The problem I also have is if I leave it on the converter boils the batteries. I found one that is made by the same company that is a 4 step converter they say wont over charges the batteries. Is this a good idea and is it better to step it up to a 100amp verses staying with a 75 amp.

      Also will this cause problems with the ac. That seems to be acting up as well now.

    working
