Reset the Circuit Breaker

As tripped circuit breaker is one of the primary suspects causing this issue, let’s talk about it first. Have a look at the circuit breaker panel in your RV. Check if any of the breakers have tripped which means that’s in the off position. If so, reset it by turning it to the on position.

Replace the Fuse

The other primary suspect is a blown fuse. There’s a fuse in the RV’s electrical system that protects the lights. If this fuse is blown, the lights will not work. The fuse box is usually located in a cabinet near the battery. Remove the fuse and visually inspect it. If the wire that runs through the center of the fuse is broken, the fuse is blown and will need to be replaced.

Replace the Battery

There’s a DC battery that starts the engine of the RV and provides power to the lights and other electrical systems while the vehicle is running. If the battery of your RV gets defective, it can’t store the necessary charge even though it’s connected to shore power. In this case, you need to replace it. 

Screw the Bulb Firmly

Sometimes the reason can be as simple as the bulb gets loose at the socket. So, you just simply tighten it by screwing it firmly.

Replace the Bulb

Over time, light bulbs tend to burn out and it’s quite normal. If the light bulbs in your RV are burned out, the lights won’t work. So, verify if this is the cause in your case. If so, you’ll need to replace the light bulbs.

Ensure Compatible Light

If your RV lights aren’t compatible with the system, they won’t work even if you connect them to the shore power. Make sure to use bulbs of a suitable type and wattage.

Replace the Inverter or Converter

Sometimes a faulty inverter or converter causes this issue. If it gets defective then it can’t receive electricity from the power source, in this case, shore power. If you find the inverter or converter is faulty, replace it with a new one. 

Frequently Asked Questions and Answers (FAQs)

Why is there no power when I plug into shore power?

Check for the 110-volt outlets. When there’s no power flow toward them, you should check the breakers, especially the GFCI  (ground-fault circuit interrupter)  breakers. Pay attention to the power pedestal if they’re all in the on position. You can’t test and reset if the GFCI outlets and breakers don’t have the applicable power.
