Dometic RM2652 was working fine then stopped - no lights at the control panel above the doors.

Usually there is a short in the system when fuse is blown. Check the cord as sometimes mouse can damage the cord. It is a posibility.
Check power to the electronic board.

Domestic Dm2652 will not work on AC without DC power is this correct. We have been camping for a week plugged into 30amp power. Refrigerator worked fine then check light came on and refrigerator...

This is an RV frig correct? It SHOULD work either/or. AC or DC. If your plugged into AC then often the frig will work with that alone. DC is for when you have no AC so you can power your appliances of the battery. Maybe you have a converter (AC to DC which most RV's do) that somehow is not getting the DC to the frig.

Refrigerator will not cool on electric or gas. When plugged in, it keeps trying to switch to gas. We switched it to gas but it would not stay lit. Checked wiring and found a blue wire disconnected and a...

Hi and welcome to FixYa, I am Kelly

The blue wire disconnected and the 30 amp fuse being pulled is typical of a DC circuit problem. What concerns me is the fact that someone had to put a 30 amp fuse in a 3 or 5 amp circuit. Maybe you meant to say 3.0 amp.

The unit uses a 5 amp fuse on J5 of the main board for AC power and a 3 amp fuse on J1 of the main board for DC power.

See page 17 of this manual:

For part numbers of parts see Appendix A in this manual:

You will need to use this manual to troubleshoot:
See step 3 page 2 to start... where is says Operation you have to perform the testing steps listed below Operation.


AC Volts


Heating Element

Lower Circuit Board

From the hip given the fuse was removed I would suspect the heating element but.. follow the sequence above.

Our Dometic RM2652 RV frig has 2 yellow lights on which are indicated to be alert lights. The frig/freezer seem to be working fine.......????? Is something about to go out on it?

The 2 yellow lites... if you would... Is there and indication by description of what those 2 lights are?

Here are the modes:



Press the AUTO/MANUAL mode selector button (2) to the DOWN position. The AUTO mode indicator lamp (A) will illuminate.

When operating in the AUTO mode, the AUTO mode indicator lamp (A) will illuminate. The control system will automatically select between AC and GAS operation with AC having priority over GAS. If the control system is operating on AC energy and it then becomes unavailable, the system will automatically switch to

GAS. As soon as AC becomes available again the control will switch back to AC operation.

If 120 volts AC is not available, the control system will automatically switch to GAS operation. Within 45 seconds the burner should be ignited and operating normally. If unsuccessful, the CHECK indicator lamp (B) will illuminate.

To restart an ignition attempt with the CHECK lamp illuminated or to clear (turn off) the CHECK lamp, press the main power ON/OFF button to the OFF and then to the ON position. The control system will attempt a new 45 second ignition sequence.

On the initial refrigerator start-up on gas (120 volts AC is not available), it may take longer than 45 seconds to allow air to be purged from the gas line. If the refrigerator has not been used for a long time or the LP tanks have just been refilled, air may be trapped in the supply lines. To purge the air from the lines may require resetting the main power ON/OFF button (1) three of four times. If repeated attempts fail to start the LP gas operation, check to make sure that the LP gas supply tanks are not empty and all manual shutoff valves in the lines are open.

NOTE: DO NOT continue to reset GAS operation if the CHECK indicator lamp continues to be illuminated after 3 or 4 tries.

If 120 volts AC becomes available while the CHECK indicator lamp is on, the control system will switch to 120 volt AC operation, The CHECK lamp will not turn off until the main power ON/OFF button is pressed to the OFF then ON position.

In AUTO mode operation, the temperature is controlled by a single temperature setting.


When operating in the MANUAL mode, the AUTO mode indicator lamp (A) will be off, and the refrigerator will run continuously on the energy source selected by the control system.

NOTE: The food in the lower compartment may be frozen if the refrigerator is left on "MANUAL" mode.


This control system contains a feature that will continue to operate the cooling system in the event of a failure of a major operating component. If the control cannot read the temperature sensor and operate at the preset temperature, then the control will run the cooling unit like the MANUAL mode.The refrigerator will continue to operate in this mode indefinitely or until a new sensor is installed and the
system is reset.

I posted the above information from the contents of the service manual. I can help you but... at the moment for sure I have come to the conclusion that ONE of the lights your seeing is the CHECK light. The mystery is... what is the 2nd light your seeing? Manual of Stand-by?

I am pretty sure we can sort this out but... we need to really communicate clearly and well. In our posts here.

Thanks for choosing FixYa,

Unplug the fridge. Remove the cover from the circuit board, unplug the 2 wires going to the heat element and do an Ohms reading should be 35-45 Ohms. If the Ohms is good then you need a circuit board as long as you have checked the 110 volt fuse on the circuit board.

My fredge rm 2652 not working

You need to check your fuses on the fuse panel inside your coach. The frig will not operate on gas or electric without 12 volt power to the frig circuit board.

Dometic rv refrigerator

I found that they rewired the 12 volt supply, red wire, thru a heat safety switch on the burner unit and it was open instead of being closed and cut off the main 12 volt supply to the control board. I connected a jumper wire around the new switch and the frig works . either the new switch is bad or too close to the heating unit.
