fuse keeps blowing help

I have a 20 amp fuse that keeps blowing on the 12v side. It days it powers lights but it also has something to do with the fridge. The fuse blows immediately when I replace it. What could be causing this. It is a 2008 sandpiper.

If its feeding your fridg. Check the electric heater located outside in the back of the fridg. It may be bad and shorted to ground causing the fuse to blow. Try running the fridg. On propane.

It's running to the fridge. I lost all the lights on the outside panel of it so I can't even tell if it was on. What does the electric heater look like? What is the purpose of the heater?

I'd take a pic of it but no where close to my RV. The heater is what heats up the heat exchanger when on electricity, just like the propane heats it up while on propane.

If you have propane you might beable to run off it. Turn your lights off and unplug the fridg. Replace the fuse and see if its your fridg or lights blowing the fuse. I text a pic

I tried replacing it with the lights off and the fridge unplugged at the 120v outlet in the outside access abs it still blew right away.

Try disconnecting the 12volt power to the frig. It is usually a black wire and a white white hooked to a small terminal block located behind the outside refrigerator access panel.
