Default Dometic Refrigerator RM 8500 Series Beeping

Greetings,

2 weeks into a 5 week trip and having problems with fridge. Replaced battery and all worked fine on all systems (12V, 120, gas) until this morning. Last night there was a huge lightening storm and power went out, beeping of fridge woke me up so I just turned it off until I started rolling this morning. Was running off 12V while driving and about 2 hrs. in the fridge started beeping. Now parked and beeping on all other energy sources as well. The red warning light is not coming on but the beeping continues. I do notice that neither of the fans are running. I've checked the fuses/breakers under the inside panel near the floor and all seems okay. I'm wondering if something burned up last night. Any other ideas?

I read an earlier thread about another fuse somewhere. I don't see how to remove the front black panel on the fridge (where the LED lights are).
I opened the 2 outside hatches but frankly, don't know what I'm looking at but nothing looks blatantly amiss other than neither of the 2 fans are working.

Thanks so much you guys!

JoAnne

Pleasure Way is 2014. I don't see any plate on inside of Dometic giving specifics and printed manual is for about 6 different Series 8500 models. Mine has LED settings for 120, 12, Gas & AU (Auto). Don't know if that helps. Thanks. Just bought a bag of ice JoAnne

mmm . . . 2014 is very new. You shouldn't even need new batteries.

Have you tried turning the breakers off, then turn on again?

Don't see an internal fuse in any of the wiring diagrams. I took a fast glance. You might want to double check.

I'd follow others advice about possibility of some sort of external reset.

Back battery wasn't holding a charge so I replaced in Bismark (left from WA). That seemed to solve one problem of the fridge not wanting to run while I was driving. But tonight not working on any of 3systems so I think it must be something internal w/ fridge.

I did flip breakers off and on again. And, I opened up exterior hatches and unplugged and replugged in cord back there. Fans were turning a couple of days ago, now they are not working.

I appreciate you taking the time and effort to look at a wiring diagram, thanks so much. Think I'll live on ice and cooler until I return home.

Does your RV have a voltage meter?

What is the battery's state of charge (SOC)?

The new battery may just have made it run because it was charged up and the old one wasn't. Now the new one is maybe not charged.


I think the place to start is with charging systems to make sure the batteries are actually getting charged, both from the engine and from the shore charger.

Does it work on propane?

How about spending the night somewhere with hookups. Does it work on 120v?

Do you have a generator? Does it work then?

I have not tried running on the generator but have tried w/out success in running on 120, 12 & propane. It seems unlikely that none of the 3 sources would operate the fridge? I didn't think that could still be a voltage problem, especially w/ propane?

No voltage meter. Guess that's something I need to pick up and learn how to use.

Thanks.
