Question about Dometic Refrigerators

1 Answer

Dometic 2811 gas/AC refrigerator poor operation on gas mode.

Refer does not get cold on gas setting. AC seems to work OK but is slow getting cold. Also when ambient temp was about 85 deg, had to turn to the coldest setting to maintain 40 deg. On gas setting it does not get cold. The ignition flame comes on and the thermocouple tip turns red but the main burner never kicks in. It has not been run in a couple of seasons. Could it need to have the refrigerent recharged or have a faulty circuit board? Does the gas valve open a little for the pilot flame then open farther to ignite the main burner or is it simply open or closed?

Hope you can make sense of this. I'm frustrated with the poor operation.

Thanks,
Paul

Your gas valve is sticking. Could be a bad thermocouple.
Set it to come on, then with a screwdriver handle or something similar, tap,tap,tap gently on the gas valve to see if it lights.
Once it unsticks it should operate OK.
If it does not unstick, replace the gas valve.

When running on Electric insure that the rear coils of the cooling unit are getting warm. If the refrigerator is level and the coils are warm and the refrigerator does not cool then you more then likely will require a replacement cooling unit. I have attached a small video that may help with the diagnoses. You can also give us a call toll free 1-888-782-6665 ArctiCold Refrigeration We keep it cold

First ensure the fuses are not blown in the electronic board at the rear of the refrigerator. Also check to see if the rear coils of the cooling unit are getting warm If the coils are not warm then the heating element may be faulty.

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:

OPERATING MODES

AUTO MODE

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.

MANUAL MODE

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.

STANDBY 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,
Kelly

Hi there. When calling for cold, flame should be large and blue. If orange, clean mixing tube, flue, chimney. If still orange, adjust "air" inlet on mixing tube to get blue flame.

One problem may be high dc volts it should be around 13.5 max your convertor may be developing to much voltage. Relay is on dc side you have more than enough. The contol board would be your next check. Some places that sell them may be willing to check if you bring it in.

AC,DC, gas RV fridge Dometic


You more than likely need to replace the control cable between the upper and lower board. It comes as a kit with the upper board. You can also do a bypass test by unplugging your thermoster from the circuit board. The thermoster is the temperature control for the refrigerator nothing to do with the freezer.
