Dometic Fridge Intermittent on 120V

That fridge has 2 elements. A 12v and mains 240v/120v. Sounds like the mains element or the fuse has blown. The fuse box is in behind the fridge at the bottom. Follow the power cord to the box. There should be 3 fuses. Check them all. Using a multimeter, check the readings of both elements. Google " Dometic Service manual DM2652 pdf" and page 11 should help you.

You may wish to check the flue clear anything that you find. Old birds next etc. Also make sure the flame and orifice are clean free from debris or rust. Propane should burn blue not orange. Incorrect gas setting if the flame is orange. Some yellow at the tip is ok. Proper adjustments are critical. Have you tried the unit on AC?
Other tips I have read indicate possible freezing in the back.
Defrost freezer completely as some here mentioned and restart see if this helps. Here is a good RV forum I saw good tips worth investigating.

If your not comfortable cleaning the jets and adjusting the flame have a professional do this. Safety comes first!
Good luck!

The DM2652 comes with an optional cooling fan to help with cooling the amonia. The fan cycles on and off as required as it has a tempeature sensor (thermistor). We turn ours off at night by removing the inline fuse (glass tube fuse 3 amp) located in your outside acces panel. The fuse is located in a black fuse holder with a re wire connecting both sides.

Check to see if you have a switch for storage, on, off etc. usually between doors, or near top right corner of fridge compartment. It may be in wrong position.

Yes, you can operate the fridge on propane while driving, instead of running the generator for electric operation. However, you should have a dual tank setup to prevent running out of propane.

Propane tanks with OPD valves aren't holding a true 20 lbs of LP, but rather only hold 17-18 lbs of LP. However, if you're swapping/exchanging your tanks instead of having them refilled, you're only getting 15 lbs of LP in the tanks these days, (check the label at the bottom of the tank to confirm). Hence the reason to have a dual tank setup on your RV to get longer run times.

I thought you might want to have a tech manual for your fridge, so here's a link to the Dometic site, you just need to select yours based on the manufacture date, etc.
