Norcold 8310EG2 blown 3A fuse

I have a 1984 Winnebago Chieftain. It has a Norcold 8310EG2 refrigerator that originally came in it. The refrigerator has worked great since we bought the motorhome five years ago. We are on a Disneyland trip and when we arrived in Anaheim the lights on the interior control panel otherwise known as the eyebrow lights were not illuminated. These lights work strictly off of 12VDC. After some inspection I found the 3A fuse on the control board was blown. I replaced the fuse and everything powers on and worked normal. I was able to get another 12-16 hours and it blew the fuse again. The first time it blew I was running it on gas; the second time it blew I was running it on electric (120vac/ its a 2 way unit). Does anyone have any suggestions why this fuse would blow? I have some thoughts, but would like some unbiased responses first. Please, any help is greatly appreciated.

I'm no expert but on the 88 Chieftain we bought the fridge didn't work when we bought it, I have found that almost all of the connections in the back of the unit had some type of corrosion on them cleaned everything up and got it going. That could cause an overdraw and blow that fuse, iffy ground perhaps. I know when we got ours most of the 12 volt things on the coach didn't work or worked intermitently, when I started cleaning up grounds everything started working right! Bobby

I had unplugged everything and plugged them back in. I then left the refrigerator light circuit and the AC heating element unplugged. We have been running it on gas and we have been good for a couple days now. So I'm not sure if it was because I reseated the connections or because one of the mentioned circuits was the issue. I'll be happy to make it home, then I can take some amperage measurements and properly diagnose the issue.

Thank you for the advice.

Similar issue ... perhaps. 1989 Chieftain ... Appliances were working great- lots of weekend trips. Then, over the winter (we leave it attached to AC) it stopped working on AC (along with Microwave- same circuit?) but works on LP.

Still have no luck ... have tried changing the circuit breaker (20amp) - no dice. Not getting voltage at the outlets. Any thoughts on what may have happened / or can be investigated? Obviously, getting in behind the appliances is not easy.

Just looking for a starting point. Thanks for any help!
