Norcold 1200 LP/AC Itasca Mederian 07

Looking for the location of the fuse that would control the change over from LP to AC. I have Good power and working LP, but when I connect and select either "Auto or AC" I get the fault "no ac". Was told there is an automotive type fuse 5-6 amp fuse that might be the problem. Need to find it. Thanks, Ken

What refer brand? On a Norcold there is a small black box on the back that has a couple fuses in it that control the input power. They are the old style glass ones. I had to go to Radio Shack to find them. As I remember they were 250 volt ones but it's been some years since I looked inside that box.

Well, is there ac power?? Your Norcold gets its ac from a wall outlet in the back of the fridge compartment, and it would not be the first time I found that outlet to be cold for a variety of reasons. Are you sure it's hot? Plug a blow drier (or any portable 120v device) into it and see. If not, make sure there is no tripped circuit breaker. My ice maker also gets its power from a second 120v wall outlet near the first. Try plugging the refer in there, they are on different CBs.

F3 - 5 amp fuse

Check the fuse labeled F3 on the powerboard. You'll have to remove the outside refer. cover to gain access. There is a black plastic cover that you'll need to carefully remove. Take photos or label your wires for putting it back together. The fuse is located on the left side of the board, just off center.

My Norcold 1200LRIM -- (which has had an AHMISH coil for a year now -- which is great)
also has a small inline fuse in the 110V hot wire.

The 110V wall box where my unit is plugged into, gets power through a small round push button breaker on the outside on my BCC (battery control center) located in a rear compartment adjacent to the batteries. (but separated by an internal panel for safety.

Yours of course will vary as you can see different RV's have slightly different electrical setups.
