If you’ve ever encountered a shorted series of electrical outlets on your RV and felt completely stumped for a solution, trust us, you’re not alone. But rest easy, the source of the problem is common, and the fix is simple. In this lesson, RV expert Dave Solberg teaches you what to do when you discover several RV outlets not working.

To help you figure out what’s going on with your faulty RV outlets, Dave walks you through a quick explanation of circuits and standard RV electrical wiring. He introduces an inexpensive tool you should use to detect which outlets are malfunctioning, and demonstrates the proper way to pinpoint the source. You’ll learn why the ground fault circuit interrupter (GFCI) on your rig might be giving you issues, and discover easy ways to avoid a sensitive GFCI. With Dave’s help, you’ll be up and running again in no time!

    I took my Bounder diesel to Quinn Cat to have some work done. An apparently inexperienced “mechanic” burnt out a board on my Xantrex Freedom 458 inverter and completely discharged and ruined all 6 batteries. After some discussion, Quinn reimbursed me for the inverter repair and batteries. Now I’ve discovered that some of the outlets on the 20A circuit won’t work with the inverter, but do work on shore or generator power. The microwave is on the 20A circuit and will work with all 3 power sources. The non-contact power indicator shows power coming out of the inverter on both the 15A & 20A circuits. Maybe he also burned out a breaker or something in the power switching unit? But the microwave does work on the 20A circuit using the inverter. Any suggestions for what I should check next?

      Hello James,

      If the outlets work when plugged into shoreline power, than it could be another fuse or breaker in-line from the inverter? Who did the repair to the inverter? Might want to get that checked out again, should be easy to tell 120-volt power coming out of the inverter and follow it to the outlets.

      Thanks,

        Mark Snyder Electric did the repair. He’s the factory repair facility near San Diego. I have confidence that he knows his stuff. From a brief description over the phone he told me that 1 of 2 wires had a short. It was the thermistor wire that the “mechanic” took upon himself to “fix” that was the problem. The RV is in in storage now so I can’t check, but I may have misstated which circuit the microwave is on. I can tell power is coming out of the inverter through both the 15A & 20A breakers by using a non-contact tester and operating the breaker off & on. I was trying to follow the wires through the walls with the tester, but knowing the path would sure help.

    Does it negatively affect the electrical outlets if you start the engine while the RV is plugged in?

      Hello Rob,

      It should not affect the 120-volt outlets of the rig starting the engine as the engine alternator is protected by a Battery Isolator Management (BIM) solenoid and is 12-volts. The 120-volt outlets in your coach are wired to the distribution center and protected with a circuit breaker and isolated from the 12-volt system as well.

    Hi there,
    While back ago my mother in law was inside the rv (we have a 99 safari zanzibar) running the generator until we coulf get hooked up to shore power. Well when the shore power was hooked up shortly later I lost power to my rv. The park hookup was apparently running “hot” well next thing I know I lost power all together. We changed out the transfer box and my ac runs on shore power until my batteries die because Im assuming mu battery charger runs off of 110. And none of my 110 outlets are working. We are currently running an extension cord through the slide out to distribute power until we can figure out whats wrong with it. Any ideas?

      Hello Kelli,

      Several things could have happened when you had the electrical issue. First you need to have your distribution center checked out, just changing the transfer switch is not enough. The distribution center has the circuit breakers for all 120-volt appliances, 12-volt fuses for the lights, roof vents and other applications powered by the house batteries, and a converter that does operate on 120-volt power to charge the batteries. It could just be a circuit breaker tripped or could be a shorted distribution center? One question? You state; “my ac runs on shore power until my batteries die because Im assuming mu battery charger runs off of 110”
      Are you referring to the 12-volt DC systems such as the lights, roof vents, and appliance on LP mode? What do you have the extension cord connected to inside the rig? I would also suggest checking your GFCI outlet either in the kitchen or bathroom as it may have shorted out as well and several other outlets are “ganged” to that one so they will not work as well. If you are handy with a multimeter, you should be able to check 120-volts coming into the distribution center and going out through each of the circuit breakers. There should also be one for the converter and you can check at the batteries for a charge coming to the batteries when plugged into shore power? It should read about 13.5-14 volts

    Sometimes the GFI in my motorhome works and sometimes it does not. It will trip and not reset after multiple attempts. Then the next day it works fine. I have replaced the GFI outlet and have the same issues with the new one. Any ideas what the problem is. I cannot rely on the outlets connected to the GFI since I don’t know when it will trip.

      Hello Ronald,

      I would start by checking the quality of the GFCI you replaced as there
      are some very cheap brands on the market? Next you need to check the
      incoming and outgoing outlets connected to that circuit. Somewhere
      you have something that is overloading the circuit and causing the GFCI to
      trip? Check all wiring as well to make sure there is not a loose
      connection.

      Thanks,

    I have a problem with my GFI that I cannot figure out. The outlet will trip and I cannot reset it after multiple attempts. Then at a later time, maybe the next day it will work fine. I cannot rely on the outlets connected to the GFI. I have replaced the GFI and have the same issue. Any idea on how I can track and solve the problem?

    I replaced my Driving battery and now my outlets and Ac do not work and I am plugged into 110.

      Hello Jeanne,

      I would assume you have connected something wrong as your driving battery has nothing to do with your 120-volt system? When you are plugged into shoreline power, the 120-volt power comes into the rig at the distribution center just like your home. In this you have 120-volt breakers for the appliance such as the Air Conditioner, outlets, microwave etc. You will also have a converter/charger which charges your house batteries. There will typically be 12-volt automotive style fuses here as well with protect the items like interior lights, water pump, vents etc. Check your main breaker in the distribution center and you might need to take a multimeter and verify power coming in?

      Thanks,

    Hi

    We have a RExhall Aerex (1994)

    We are getting ready for our first trip of the year, and are testing everything…we have our RV plugged into our house.

    All of the front outlets are NOT working…the ones in our bedroom do work!

    Any ideas??

    Thanks!!

      Hello Mike,

      Unfortunately there is no “Easy Way” redo floors and interior walls and if you are not a “good mechanic” as you stated, or have experience with flooring and remodeling, it’s not a DIY project that I would suggest! The walls are a sandwiched design with interior paneling laminated to block foam insulation with integrated aluminum framework or wood in less expensive model. Then a thin luaun wood panel and fiberglass outer skin laminated so a “redo” for the walls in pretty intensive! If your are looking to just change the color, I would suggest painting or applying wallpaper as the covering you have now is a wallpaper applied to a panel just like you would find at a home improvement store. You can’t just cover with new paneling as the thickness would create issues at the windows and other areas.

      As for the floor, you probably have carpet and want to either replace it with other carpet, or another material. The challenge is getting a covering that will withstand the tremendous push of your slideroom and not tear or bunch up. Also, you will have twists in the chassis when driving which will create an issue with wood or tile flooring as well as huge temperature changes which will make the material expand and contract.

      We just completed a renovation of a 2002 Winnebago that had carpet and 2 slide and installed a Luxury Woven Vinyl product from Infinnity which will be posted on the site next month. Look for the videos coming soon.

      Thanks,
