If some of the electrical components in your RV are not working, the issue may be related to either your 12-volt (DC) system or your 120-volt (AC) system. Follow the steps below to help identify and resolve common power problems. 


If Your 12-Volt Battery Powered Items Are Not Working 


The 12-volt system powers many essential components in your RV, such as lights, fans, the water pump, and certain appliances. If these items are not working, try the following checks: 

  1. Check the Battery Disconnect Switch Locate your battery disconnect switch and make sure it is in the green or ON position. If the switch is off, your camper will not receive power from the battery.
  2. Inspect the Main DC Breaker Some models include a main DC breaker that protects the 12-volt system. Make sure the breaker has not tripped. Note that some models, such as the TAG or TAB 320, may not have this breaker. 
  3. Check the Fuses in the Power Distribution Panel Open your power distribution panel and inspect the fuses. Look for any blown fuses. Replace any fuse that appears damaged or burned. 
  4. Inspect the Battery Terminal Fuses Check the fuses connected to the positive terminal of your battery. A good fuse should look intact inside. If the fuse appears burned, melted, or broken, it will need to be replaced. 


If Your 120-Volt Power Is Not Working While Plugged In 


The 120-volt system powers outlets and appliances when your RV is connected to shore power. 

  1. Verify the Power Source First, confirm that the outlet you are plugged into has power. An easy way to check is to plug in another device, such as a space heater or a phone charger. If the device does not power on, the outlet itself may not be providing electricity. 
  2. Reset the Circuit Breakers Sometimes a breaker can trip without appearing obviously switched off. To reset them, turn all breakers completely off then turn them back on. 
  3. Reset the GFCI Outlet Look for a GFCI outlet, which has a reset button on the face of the outlet. Press the reset button to restore power. Even if the outlet that is not working does not have a reset button, it may be connected to another GFCI outlet nearby, so check other outlets in the camper.
