1992 U225 Refrigerator Fuse.

Okay, I did something stupid and blew the 12V fuse for the refrigerator.  I can't find the fuse.  Any Idea where it's hidden?

Foot of the bed, passenger's side is the 12 VDC fuse panel.  May also one at the back of the refrigerator.

No joy. BTDT, also looked around under the dash cover. Tested the circuit breakers.

I'm looking for a 30A fuse.  The Dometic RM 4804 is a 3-way fridge.

You are running the heat element (vs only the PC board) on 12 VDC while plugged in???

You do need 12 VDC for the PC board.  But, on shore power, you should be on 120 VAC for heating element.  Fuse for the 120 VAC is on the PC board.

The 30A feed provides the power for the controls, and if necessary the 12V heating element.

I found the fuse!  It is in the battery compartment along with a couple of big circuit breakers, 2-10A push to reset breakers and 2-15A push to reset breakers and a lonely 15A fuse.

Today was going so well I decided to install the new ignitor.

I had a good brain freeze going so I lugged a 12V battery over and powered the fridge off of that.  The propane side now works as it should and I knew I had refrigeration for the night.  So I went back to Lynn's suggestion and pulled that cover in the battery bay and voila there be fuses!

Everything is back where it belongs, I didn't get everything done I wanted but I'll throw the big toolbox into the bay, coil up and throw my power cord into it's bay and be pretty much ready to go tomorrow morning.

And yes the fridge will be running on 110V tonight.  In theory when I disconnect the power tomorrow it will automatically switch to propane.


Thanks for the help Brett,
