I have a Norcold fridge in my 5er listed in my sig. it keeps popping the 5 amp buss fuse inside the black box that covers the mother board. ive checked all the wires, no bare spots to ground out. i was told by a RV serivce guy that the heating element might be bad. anybody have any other pointers on what i can look at?

Guess you can try unplugging the heating eliment and turning it on, or unplug heating eliment and try starting it with gas. If it doesnt blow fuse then eliment is bad.

 

it will run on gas fine. there are 2 fuses on the board, i believe a 3 amp, that runs the 12 volt for the propane, and a 5 amp that runs the 110 part. i know there juice there. i tested it with the wifes hair dryer. it doesnt pop every time thought. the last trip we went on it popped as soon as i plugged the RV in. changed the fuse and it worked fine. plugged it in in the driveway today and it popped the first fuse as soon as i plugged it in, the 2 more as soon as i put em in

 

I had a heating eliment go bad, 5 minutes after turning on the refrid. the ground fault would trip and cut off all assoc. circuitry. Took a little while to figure hat out. But try disconnecting the heating eliment from the board and then plug in trailor and see if fuse blows.

 

thanks for the tip...will give a try
