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!

      Thanks Randy. I am stumped. Other than a high pitched noise and the slider not working when the converter breaker is on, everything appears to work fine. When turned on, the convertor appears to be producing approx. 12.7 volts. All 12 volt fuses read 12+ volts across each side, it just doesn't allow the slider to work. Once the breaker is off, then the slider works just fine. Weird hey?

      Everything in our trailer works fine (12 volt and 110 volt systems)except our slide out does not work when plugged into shore power, and I noticed a very faint, but high pitched noise. I determined it is coming from the converter. When I turn off the converter 110 volt breaker the squeal goes away, and the slider then works. It appears everything works with this breaker off.

      Does this mean I have a faulty power convertor?

      Annette, check the negative battery cable where it attaches to the steel frame of the camper. A rusty of corroded connection can cause this problem.

      Does the battery furnish power to the lights when not connected to shore power? The converter doesn't work when not plugged into a110 volt source, so the converter may not be the problem.

      Randy we have a weird problem, we had a battery run low and could not put the slide in. We tried to put the slider in with electric and it wouldn't work until we charged the battery. Now, we bought a new battery and the only thing that works on the 12 volt is the slide. No lights no nothing. If we use 110 everything works. However we only camp and use 12 volt due to love being way out in the woods. Another thing that happens is when we have it plugged in to 110 and push the buttons for grey water and battery life and etc, everything lights up like it should. Then we unplug the 110 and go back to 12 volt we only get a slow flash of a few of the red lights on that grey water and battery life. We have checked the fuses and put in a new battery. What else is going on to where we have partial use of 12 volt to where only the slide works? We have a 2010 Catalina Coachmen travel trailer. We are not sure if it could be the converter, even tho it is 12 volt that we are using? Any ideas?? Thanks!

      Bryan, a GFIC is a very sensitive thing and the slightest lack of ground can trip it. I assume you're not using a small extension cord at home? But there could be a bad ground causing this as well.

I just hooked the battery up to my truck battery like a jump start, and power has come back to all 12v utilities. What would be the steps I should start taking to get this issue fixed? Thanks! I'm not even sure where the converter is, I'm quite new to the rv thing. Getting my manual out to see if I can find the location now.

      I had my 98 sportsman travel trailer hooked up to shore power and the Pos terminal on my battery melted off. Is that caused by the converter? Also the last time I towed I had a short in my 7pin trailer harness with the + and - wire on Tow Vehicle the + and - terminal on the trailer connector all melted and I was thinking maybe the two issues were connected

      I have a 2013 Lance 1895 camp trailer. Used it for the first time boondocking this weekend. Plugged my 650 generator to charge the RV, and after about 5 minutes I heard a loud pop and smoke was coming from the Power Distribution Center. I quickly unplugged the generator and propane. What would cause this? All electrical systems seem to be working fine, but I towed it home with batteries unhooked just to be on the safe side.

I went camping last weekend and could not put my slide in as the battery ran dead. I was able to after a boost with the truck. I replaced battery and over the week this one went dead too. I don't think the convertor is charging the battery. bad convertor or can this be a ground problem?

      Steve, if you haven't replaced the battery yet, then do so. It may be your converter cannot supply enough amps to the system with the battery backup. The GFIC isn't related to the 12 volt system at all. It is possible the converter may be acting up as well.

      Thanks for your help. The noise itself was coming from the spark it was shooting. everything seemed to be working fine until today. My son just informed me the lights are going dim and the radio stopped working. I am assuming that means the converter is not charging the batteries, hence, not working. Am I right? I just took it out(the converter). Can you tell me what I can do to see if it is fixable, or should I just buy a new one?

      Now everything is back to working normal(with or without the converter breaker on), but it is still making the spark/pop. Although it is much less now. Before it was doing it every 10 seconds or so. Now it is doing it after about 1 minute of turning on the breaker, and I don't know after that.

      Catherine, unless the converter breaker is shorting out, the converter shouldn't affect the 110 volt outlets. If you have more than the one GFIC, I'd replace them as well. They are notorious for causing problems when they get old.

      Problem I am having are the electrical outlets. Had the 2 on the kitchen island stop working last year. Repair guy still trying to figure that one out. made call to manufacturer, he is waiting for call back. But, last weekend, the electrical outlet by the kitchen sink stopped working, then the one in the bathroom.

      I did notice the GFI in the bathroom, the two buttons, top one is out. Having a friend replace the GFI.

      The number 15 fuse for the kitchen I replaced, sink outlet worked for 10 sec then stopped working.

      Could this be all be connected to the invertor for me having all these problems

      Hey guys. I had a similar problem with my truck camper. Everything seemed to work fine on shore power. When I switched to 12 V, monitor would not work. Fan on stove exhaust vent ran but would not open the vent cover, furnace fan ran but furnace would not ignite. I posted with Randy a couple of days ago and his response to check the ground lead me on a little trip. I discovered that the positive lead from my battery was hooked up to the ground buss and negative to the positive buss. I switched them over and now everything works just as it should. Hope that helps.

      Dave, have you checked for an inline breaker on the positive battery cable going to the converter and power panel? Some RVs have this and some don't. It should be located near the battery box in most cases.

      My problem is a bit different. My shore power thru the converter works fine. The lights(for example) operate. The battery side of this is the problem. Battery reads 12.6v. Power is getting to the first wiring junction. The grounds to the frame are also conducting. I checked the grounds to multiple points on the frame and all are ok. The dc voltage is not getting into the dc panel (coverter box) and the battery monitor on the wall shows zero volts. Monitor works fine on shore power. Truck power to driving lights is ok also. I really don't know how they transfer the two voltage supplies (throw over system). Next step would be to remove the converter from the cabinet and check dc from battery. Any info on the throw over would help.

      Jason, turn all of the breakers off including the main in the 110 volt AC power panel. Turn on the main and then flip on the breakers one at a time until you find the circuit causing the short. Once you find the offending circuit you'll have to see what's causing the breaker to trip.

      Clarence, it depends on what other items are being powered as well. All of the thermostats--fridge, heat H/W heater--are on the system as well, even if the lights are off.

      It may be the converter is getting weaker and the lights pull more energy than the other items causing the converter to come on.

      Hi Jeri, the next time you plug into a new house first turn off all of the breakers except the main. Then you can turn the breakers on one at a time until you find the breaker which is causing the main to trip.

      When you've found the circuit causing the breaker to trip you can probably work around it or find what's causing the problem.

      Hope this helps, but if not, get back to me and we'll try something else.

      I wanted to get your advise on my camper trailer. I have it parked in my mother's yard. I am not planning on moving it. It has new tires on it. should I have the tires removed and put up, so they don't ruin or go flat?

      Yes, you should at least have a battery box located somewhere on your camper.

      I do not have any batteries or battery cables. If I do I don't know where they would be. I brought this camper used. And I am new to this, plus a elder lady with no help. Should there be battery cables and where would they be located????

      The battery, Lavenda. Or the battery cables if the battery is missing.

      Lavenda, you can use a good battery charger until you get a replacement fan.

      I had to buy me a new wfco 8935 converter for a 115 camper trailer. Now the fan on the converter has stopped working. Could you help me please.

      Kyle, connect a good battery charger and if things work as usual, then the converter is at fault.

      Our lights have been fluttering on and off or surging for about a month. Now all the sudden they just shut off but come back on a few minutes later. Here's the kicker just the lights and the fridge shut off. Could this be the converter?

      Neil, if you're simply using the converter to operate the lights and thermostats you should be able to use the converter without a battery.

      Do you have to have a battery connected to the converter for it to work as I don't want to charge any batteries I just need the lights and thermostat to work.

      Robert, this sounds like a converter going bad. Try connecting a good battery charger and if everything works normally, the converter is bad.

      When my refrigerator, water heater and lights are on and the heater tries to kick on, everything surges. Turn off the lights and it quits surging. Where might my problem be?

      Justin, you need a high amp charger instead a trickle type. Have you checked the fluid level in the battery? Also check the negative battery cable where it attaches to the frame. This connection is prone to corrode and cause problems. Let me know if any of this helps.

      Hi Mariana, perhaps the fan has gone bad and the smell is coming from the overheated converter. If it's the fan, a replacement can probably be found on the net for minimum cost.

      Our converter smells like there is a short. And the fan does not run. My husband increased amps but the problem remains.

      Ben, have you cleaned the negative battery cable where it attaches to the steel frame of the camper? If so, try connecting a good battery charger and if everything works okay the power converter is probably bad.

      We have a 2005 18 foot Rainier travel trailer by Thor. Our electrical problem is when plugged in to 110v everything works fine but the 12v does not when unplugged. We have a new battery with full charge and all termanals connections have been cleaned also all twelve volt fusses are good. Please help! Thank you

      Travis, check the negative battery cable where it attaches to the steel frame of the camper. This is the main ground and sometimes it will corrode.

      Also, connect a good battery charger up with the converter breaker off and if everything works normally the converter is more than likely at fault.

      Sandi, have you tried resetting all of the breakers--both 12 volt DC and 110 volt AC--yet? This is apparently a warning of some sort but you'll have to run it down before I can help you.

      With MH plugged in to 30amp 110V service 12V lights dim and then go bright again.

      I disconnected my battery, lights stayed on and then went out after a few minutes.

      I reconnected my battery, lights went on and the dimming/ bright cycle continued.

      MH battery is a year old.

      Could be the campground? Another MH with LED lights traveling with me had no problems.

      Mitch, apparently there's a relay behind the dash affecting the 12 volt system. It may be tied into the vehicle system in some manner. I'd look for the relay first.
