Norcold fridge? Mine was a Norcold. There was a "mode" pushbutton. That would scroll through the different power options. You sure it's set to a/c? Assuming that it's set to a/c. I would open up the access panel on the outside behind the fridge. Be careful with those plastic clips. You turn them with a coin 90 degrees. Then carefully jiggle the panel out. You should be able to see the receptacle that the fridge is plugged into. Unplug the fridge and plug in a tester. If you don't have one you should buy one. At the home store. They are good to keep on hand. Has two amber lights and one red. Easy to plug in there. You should see two ambers lit and no red if it's wired properly and working. If you get no lights then go to the circuit breaker panel. Hopefully the one for the fridge is labeled. Take the panel cover off and use your volt/ohm meter to probe the terminal on that breaker to see if it's putting out roughly 120 volts. I've seen circuit breakers fail and the handle appears to be on. Yet no current is coming out of the breaker.

any error codes? if not its probably not getting power.
is the 120vac power plug "live" (mine is outside under the vent cover iirc).

if its running on Propane then the 12vdc supply is probably fine (check that fuse too, but i doubt thats the problem).

turn it off & on (again) after waiting 20 or 30 seconds resets it (i usually end up having to do this when it switches to propane & doesnt start right away).

on my nor cold (841) iirc there is a fuse outside on the power board, which is behind the exterior vent cover, the power board is in a small white box w/ some connections in/out of it, pull that cover.

also if you've got a norcold these part/location & diagrams might help

Google Results - Norcold fridge won't run on ac voltage

Bob86ZZ4 · 06-04-2016, 06:28 PM

I have one other thought. How do you know it's running on propane?

samcrimm · 06-04-2016, 11:43 PM

I have a dometic ref.
The ref has a light for ac and propane, thats how i know
Dont think it works on 12 volt
Its side ways pic sorry
Ill try outside tomorrow and see what happen
Cut it off for a few minutes to see what happens.

Report tomorrow

12v is required to operate the display and fire the burner, and for the interior light bulb.

If its running on propane 12vdc is being delivered.

It might be worth checking all the GFCI outlets to make sure they're not popped....its a long shot the the fridge 120vac outlet could be on a GFCI, although i doubt that.

Bob86ZZ4 · 06-05-2016, 10:26 AM

Looks like it's set to "auto" in that picture? I'd first pop the access panel off outside and plug a tester into that receptacle. And don't plug into the other half of it. Unplug the fridge and plug your tester in where you unplug the fridge. I've seen where they only have the half of the receptacle hot.

I'm not familiar with dometic fridges, so was that (glass) fuse was on the power board outside?

samcrimm · 06-08-2016, 12:24 PM

UPDATE!

The ac started .... Well it just didn't short out again. So the ref. Was not working on ac, I had been thinking why the fuse poped, and I should have look harder but guess I didn't need something to work on right now. So I had to find out why it was not cooling, and this is what I found! Got a new one ordered. I took the 120volt fuse out, The gas would not start, the gas valve worked but the started didnt. So to get the cold going I put the grill lighter in there and got it going. So Now I have to trouble shoot the igniter! The picture won't turn right on my pad

I'm confused, is that the gas orifice thats all smoked (and melted)?

you might have too much gap on the sparker (or it may have rusted & broken to the point that it won't spark).

samcrimm · 06-08-2016, 10:07 PM

That's the 120 volt heater that burned through, I ever messed with the gas, till I had to start using it and then for what ever reason it would not start only with my help and the grill lighter. Picture is of the other end (where the wires go),
looks like I could have burned down the house, but never smelled anything or noticed anything till I caught the gas lite on the Ref. That's when I got on here to ask my questions. Just another day in the life of RVing!

I have also messed with the pictures till I have given up, something with this samsung pad wont let the picture post as I have edited them. Sorry, I know what I am doing but it does not show here.

hot rod · 06-09-2016, 12:28 PM

wow. I can't believe it did all that before the fuse finally blew! I'd make sure you have the proper fuse size in there when you get it going again.

samcrimm · 06-09-2016, 09:10 PM

Yes it is and I checked the instructions and it was even the right one. 250 v 5A. Took a lot of burning thru before it shorted out.

NEW UPDATE

Got the element out and the new one in. Hard as hell to get the old one out, just had to twist and push up and a hit with a hammer sometimes, the new one fell in. Hooked up the wires and put the fuse in and gas shut down and the ac started..... just have to monitor things today and make sure its working. Picture of the burned up unit and the wires.
