When arriving at your campsite after battling miles of traffic, and trying to keep your cool at all those clueless drivers, all you want to do is relax. You plug your RV into the power outlet – and; nothing. Darkness looms inside, and there’s no hum from the AC.

Don’t let this ruin your trip and everything you’ve worked for with all those hours on the road; there’s a few things you can try. Don’t worry; none of these tips are too advanced either, so anyone can give them a go.

You’ll be kicking back and relaxing before you know it.

So, let’s find out exactly what to do when your RV Plugged In But No Power?

What Can Be Done?

As with anything electrical, safety should always come first. If you lack confidence or are simply unsure, stop what you’re doing and don’t take the risk. Paying a professional is always better than risking injury or death.

With that being said, there are still some relatively safe options to run through, which could have you back up and running quickly. I have created a list of options, which will be covered in further detail.

  • The main GFCI needs resetting because it’s been tripped.
  • Reset the main circuit breakers at the power pedestal.
  • The main 110 V circuit breaker requires resetting.
  • Check your batteries.
  • Check inverter response when batteries are disconnected.
  • Disconnect the power pedestal from shore power and reset the RV breaker.
  • Inspect diagnostic lights for power surges.
  • Check the charger/inverter and generator if you have one.
  • Test for power between power transfer switch/power cord and inverter/converter.
  • Inspect the wires on the breaker and outlets.

While this might seem like a lot of steps, don’t forget this is a troubleshooting guide. I have started with the most common and simple issues, so hopefully, you will have the issue resolved fairly quickly and won’t need to go far down the list.

The Main GFCI Needs Resetting Because it’s been Tripped

I should start with what GFCI stands for. It is the Ground Fault Circuit Interrupter. It is designed to break the circuit if there is an imbalance between the incoming and outgoing current. The exact location can be found in your RV owner’s manual but is often located in the bathroom.

You should familiarize yourself with the exact location of your GFCI and how to reset it before traveling. This is probably the most common problem you will encounter when having any power issues, so it’s a good place to start.

Reset The Main Circuit Breakers at The Power Pedestal

If your GFCI has been reset and is operating correctly, the next stop should be your power pedestal. Open up the box and ensure that all the circuit breakers are switched to the “On” position one by one.

Luckily, this will most likely be a simple switch to inspect, and you won’t need to feed any fuse wire. If you are working with an older RV and it doesn’t have a modern pedestal circuit breaker, do not attempt to repair fuses if you are unsure.

The Main 110 V Circuit Breaker Requires Resetting

While you are inspecting the circuit breakers, it is worth switching the main 100 V switch off and then on again. This will complete a reset of the main power supply to the entire power pedestal and often resolve any power issues.

Check Your Batteries

With all the circuit protection operating correctly, next is to do a visual inspection of all your batteries, checking for any damage or leaks. This may very well be the source of your troubles, particularly after traveling a long distance with exposure to excessive movement and vibrations.

In extremely cold temperatures, batteries are also prone to freezing. If there is any damage to your batteries, don’t forget that the contents of a battery is dangerous and corrosive. Make sure you wear the correct PPE if handling a damaged battery.

Check Inverter Response When Batteries Are Disconnected

After inspecting the batteries and there are no signs of damage or leaking, the next procedure would be to disconnect them from shore power. Try connecting them to an alternate power source and check if everything is working.

If suddenly you have power, you know the issue isn’t with the RV, and it is a problem with the shore power. In the instance you still don’t have power, though, disconnect the batteries from your RV and check the inverter. If you see any warning lights, your battery might have internal damage and will require replacement.

Disconnect The Power Pedestal from Shore Power and Reset The RV Breaker

If you’ve made it this far and still don’t have any power, you have now reached the point where you’re going to require some tools. Make sure you have either a test light or a voltmeter in your RV toolkit. You do have an RV toolkit, don’t you? Because you shouldn’t travel anywhere without one.

First disconnect from shore power, then reset the breaker. Using the test light or voltmeter, test if the outlet has power. If power is present, turn off the breaker again, and reconnect the shore power. Switch the breaker back on and test where the shore power connects to the RV.

Inspect Diagnostic Lights for Power Surges

If there is power flowing through the RV and shore power connection point, your next course of action is to check the surge protector if fitted. There should be some diagnostic lights to indicate if there are any issues. A fault in the surge protector will prevent power from flowing through your RV.

Check The Charger/inverter and Generator if You Have One

After giving the surge protector the all clear, if there is one fitted, the next item to check for power is your charger/inverter. If your RV is also fitted with a generator, also check for power in the transfer switch.

Test for Power Between Power Transfer Switch/power Cord and Inverter/converter

At the same time, you should confirm that power is flowing between the generator’s transfer switch and the charger/inverter. Every model will be slightly different, so you may need to consult the owner’s manual for more detailed instructions.

Inspect Wires on The Breaker, and Outlets

The final test involves accessing the main 100 V breaker and any internal wiring. Unless you are completely confident, then you will most likely require professional expertise at this point.

If you are confident, though, you can remove the panel to gain access to the main 110 V circuit breaker. With the wires exposed, check for power flowing through the breaker’s output. If it is detected, then the breaker is most likely faulty and will require replacing.

As a final option, the wiring between the breakers and the power outlets might be damaged or faulty. This can be a rather involved process, hence why I have left this as the very last option to try.

How to Prevent RV Power Issues?

Being familiar with how your RV works is an important step in ownership. You should take a look at your owner’s manuals to familiarize yourself with any equipment you have onboard and how to read diagnostic lights.

Having a tool kit stored somewhere accessible is also very important. Due to the nature of RV travel, you never know where or when it could come in handy. The last thing you want is to be on the side of the road without a screwdriver and some pliers.

Charge Your Batteries

RV batteries work just like a car battery would. The biggest difference is the variances in loads, depending on what is in use. They also might not operate as frequently as your car battery, resulting in discharges.

Keeping your batteries charged and maintained can easily mean the difference between an enjoyable trip and a forgettable nightmare. Plan ahead, and ensure all your batteries are fully charged before heading off.

Don’t Leave Things Running

It is a good habit whenever you are using anything in your RV to make sure it is completely switched off or even unplugged after each use. Even appliances drawing a low current can leave you with a flat battery over time.

If you are planning on storing your RV unattended for an extended period of time, make sure all major appliances are unplugged. Items like refrigerators, air conditioners, or heaters can put tremendous stress on power supplies.

Final Thoughts

There’s nothing like getting out on the open road and exploring the countryside. Especially when you can do so from the convenience of your RV, with nearly all the comforts you would normally enjoy at home.

That enjoyment can quickly turn to anger and frustration if you are not properly prepared and if you aren’t familiar with the basic workings of your RV. It would be worth going over this guide at home, so you can be prepared for any failures while you are away.

While you shouldn’t expect anything to go wrong, having some knowledge and understanding will keep you covered.

Happy adventures.
