Dometic RM2620 Refrigerator - Answered Questions & Fixed issues
Dometic Refrigerator Model RM 2820 Stopped working
Hi Tom,
If your fridge quit working altogether, check your DC fuses in the fuse box, as well as the back of the fridge under the black plastic cover (3 amp). Though the fridge uses LP and 120vac to cool, it is controlled by 12 volts.

It sounds like your cooling unit is going out. Here's a couple of things to check. Do you smell any
ammonia when you open either one of the doors? When you look at the rear of the
fridge, do you see anything that looks like rusty water that has run down any of the metal tubes and dried up? If the answer to either one of these is "yes", then
youll need to start looking for a new fridge or replace the cooling unit on the one that you have.

I would start there before replacing any parts. The circuit boards require 12volts to operate the refrigerator. If you have a good 12 volts and the LP tanks are full and the flame lights but the unit does not cool then you probably have a bad cooling unit. But start with the obvious issues first.
Dometic 1402 won't self defrost
Verify that you have at least 11.5vdc, you will typically have around 13.6 but sometimes power loss will cause the unit to not function properly. If you do have good voltage and the refrigerator is going into defrost mode but not defrosting the culprit more than likely will be a bad defrost heater.
Lights on but dometic rm2611 not working?
I am sorry that you have been so vague, but I will try to help you. The first part I would check would be the fuses. When checking them, see what the fuse looks like - black on the glass means that there was a short that caused the fuse to blow - if the element is just melted, then there was just too much draw on the circuit. If it is a fuse that is not black, just replace the fuse being sure of what amperage (AMP) the fuse is. You could have a 3-amp, 5-amp, or a 35-amp fuse.
If the fuses are not blown, then you have a more serious problem and you should take your vehicle to the dealer.
2 year old RM 2620 fridge, stopped working. I have
On the back side of the unit there will be a small thermostat switch mounted on the heat column. It will be round with two wires attached to it. In the center is a reset button. If this button does not restore power then the next step is to replace the wire coming from 12v supply to the thremostat switch. The wire will be red and will have a black sleeve on it. Under the sleeve is a safety diode (to prevent overheating and fire), it will be held in place with three bendable metal fingers. If the diode is bad it will not allow 12v power to pass through to the circuit board. Even though the refrigerator is running on 110v power the circuit board still requires 12v power to operate. The diode is a part of a FREE recall kit offered by Dometic so your local RV repair center should be able to help you out.
Fridge not defrosting
Hi Karen,
my name is Roger and i'd be glad to help you, all refrigerators are similar when it comes to defrost systems, some are computerized while others work with a timer. In order to diagnose this issue yourself, you will need to let the unit defrost by turning it off or if you have a hair dryer you can expedite the process.
Also you need a voltage meter to measure continuity and resistance on the components. If you don't have one, you are better off calling a tech.
hope this helps. I’m happy to help further over the phone at

Dometic DM2652 quit working on elec,tried gas worked for a little than quit,wont cool can hear it running.
If you can hear it running and it sounds like it is gurgling or boiling then it is you cooling unit that has leaked. Your cooling unit is charged with hydrogen and ammonia. When the hydrogen leaks it causes the ammonia to boil more rapidly, hence what you hear. You will require a new cooling unit for your refrigerator. This is something that can be done by anyone in just a few hours with no specialized tools needed. You can give Arcticold a call toll free (1-888-782-6665) or check out our online
Store I have also attached a how to video for the installation of a Arcticold New Lifetime Warranty cooling unit.
Freezer and refrigerator not working. However, Light comes on when door is opened.
Since your light comes on, it shows that your refrigerator DOES have power coming in. As for why it's not working let's try the simplest thing first. Since you did defrost it, I am going to hope that you also cleaned it our by wiping it down on the inside to get rid of any water that may have come from defrosting it. When you did this, it is possible that you changed the temperature settings. Check to see where those settings are and I will bet that they are set to the "warmest" they can be.
