Dometic refrigerator all of a sudden not working after sitting for months

So I parked my motorhome for the winter back in October and I went to turn the refrigerator on today and it will not come on either in 12 V or 110 V mode and when I parked it for the winter it was working just fine. I am puzzled because nothing has changed and all the 110 outlets and 12 V lights are working in the coach. I also checked all the circuit breakers and reset them all and still cannot get the refrigerator to come alive so I am wondering would a refrigerator go bad just sitting?? This is a Dometic model NDR 1292 product number 9211480Ė40.

How do I go about troubleshooting this issue? I canít even find where it is plugged in.

Fridge requires 12VDC to function on AC or GAS

Does the upper display come on...interior light come on?

remove exterior access/vent cover so you can check the backside of fridge
Need to verify you have 12VDC to the terminal block/to circuit board
Then you will have to remove the cover on circuit board and check the FUSES on circuit board

3A Fuse.....above the J4 terminal on circuit board is for the DC
*Comes from the DC Terminal Block

5A Fuse.....above the J5 terminal on circuit board if for the AC
*Comes from the AC Power Cord

Something like this happened to me. I removed the front control panel and discovered moths had gotten in and built nests. I cleaned it out and it worked fine.

I would start at the ref. Power wire at the back of the ref. If you have 12 volts at the inlet wire, I would next remove the cover from the board housing. There is fuses in there. Check for corrosion or a loose or blown fuse. If all is good, I would clean all connections to the board. If all is good in the back, I would go back inside the coach and check the eyebrow.
It is probably not the board. I have never had a board go bad from sitting. I have seen some changed and the refrigerator Start working, but the old board worked in another ref after the connections were cleaned.
I have repaired dozens of refrigerators this way.

FWIW over 80% of all 12V issues are the result of a poor/missing ground. Connections corrode when unused for a length of time.

If it sat the LP can he reluctant to start it can take more than a few tries and the panel will fault. Also spiders are known to be attracted to plug the air/gas mix tubes. They make a brush to fit but I've just used a few fuzzy pipe cleaners at a time instead. You can blow them out but webs can really thick if pressed together.
