If it doesn't click or the light doesn't flicker it is probably either you don't have good strong 12 volt power getting to the fridge(12 volt required only to light on gas the first time) or else the little gas igniter module went out looks like this only sometimes black.

Now if it won't stay lit. It is something wrong with either your flame or your thermocouple. First try just blowing out the the flu right where the flame comes out blow compressed air in so if there is dirt or cobweb in there it comes out the back side. If that doesn't help disconnect your thermocouple and wipe the end and then connect it back up and tighten it. If it still wont stay lit still replace the thermocouple.

Make sure the auto switch is in the down position (auto mode) the fridge will select a/c or lpg itself.

My camper has a dometic RM2652 refrig. the electric works, but it won't transfer to butane


Most dometic refrigerator have a button you need to push when you shift the mode switch to gas. This button holds the gas valve open until the thermopile generates enough power to hold the valve open. So on most shift the mode switch to gas, hold the button until the flashing light goes out. The flashing light indicates the gas valve is energized and the unit has shifted to gas mode. Depending on when the unit was last used it may take up to 5 minutes for the gas supply to purge the gas lines to the refrigerator. So be patient.
Hope this helps.

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,

Ian - are you pushing the igniter button rapidly while holding the gas supply button in? This works for us. If you have any fluid in the gas line it will not light; you would need to get this checked out. Access is through the bottom outside vent. Good luck.

Fridge will not work in gas mode.


You mat have to clean the pilot light and the ignition lube. Spiders like to build nests in the tubes which obstructs the proper gas flow.

I have a Dometic fridg in my 2005 motorhome and when I start my f


You need to unpush the gas button on the front control. If the gas button is pushed in, then it is trying to run on gas and with the tank empty, it is unable to light. That is why the check light is coming on. If you turn the gas side off and have it on auto, it should switch to the AC side and work fine.

Hope this helps,

FRIDGE WILL NOT IGNITE IN GAS MODE


The part you are looking for is the thermo couple. It senses the heat from the flame and holds the gas valve open. The clicking will try three times and then go into lock out. You then will need to reset on the front of the fridge. When installing the thermo couple do not over tighten.
