Dometic 3 way fridge not working on gas at night

Our Dometic 3-way fridge freezer has begun playing up in our motorhome. In the evening/night when on gas, the gas fails to ignite. We hear it clicking for a while and then give up. After trying a couple more times it starts beeping. Not a problem during the day when it works fine. Is it something to do with the temperature? The thing is that it's not that cold at the moment and we have been in far colder conditions (e.g.snow). Any help is appreciated!

    I am going to first sugest to do a direct test on the cooling unit. You will first need to locate the 110Volt heating element on the rear of the refrigerator. It is located in the tin stack on the right hand side. After locating these two wires, you must plug them in to a 110 Volt source. You can do so by cutting an old extension cord and splicing the wires to to the heating element wires, then plug the extension cord in. This will by pass the thermostat and run your cooling system wide open. If your refrigerator works in a direct test then the problem is your thermostat. If you need any more info, please feel free to contact my company Arctic Cold Refrigeration @ 1888-782-6665 or by email

    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.

    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.

    SOURCE: Freezer working, fridge isn't.

    It is possible that your cooling unit is failing due to a blockage. The solution used to cool starts at the top of the fridge and works its way to the bottom. If there is a blockage in the cooling unit it could produce the symptom you have explained.

    Ok, I realize I'm a little late on chiming in here, is this unit located in a slideout, and/or the top outside vent is in the wall not a roof located vent?

    If so then the issue is that there are fans that are necessary to circulate air thru the hot coils. And there is probably a malfuntioning thermostat to turn these fans on/off. I had this issue with same fridge in a Gulfstream motorhome, and the temporary fix was to pull the faston connectors off the thermostat and tied them together with a 12V fuse, and taped it up with electrical tape to keep it from shorting on fridge chassis and parts. Replace the thermostat at your conveniance, as these fans are now running whenever fridge is on, and will run your batteries down if not plugged into shore power.

    Fridge not working on gas at night

    You may need to put a heating blanket on the LP tank, the temperature determines the amount of pressure on the tank and when the temp drops you lose propane pressure thus no ignition and a lockout alarm.

    We have a 3 way Dometic fridge in our caravan. Have lived in the van for last 12 months ( grey nomads) have had no probs until trip home this week from Yulara to Victoria. Pulled up at night and freezer...

    Temperature does play a big part in the efficiency of the fridge. The condenser at the back of the fridge needs cool air flow to allow gas vapour to be converted back into a liquid.again.

    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,

    It sounds like the thermocouple is either faulty or incorrectly installed. In other words the sensor bulb may be very slightly to far away from the flame to get sufficient temperature to keep the gas flowing. This is a safety device to cut off gas supply should the flame blow out. But if you are parked at a bit of an angle, the flame will also angle away from the sensor, causing it to shut off gas supply. With regards the freezer being temperamental, this is a strange one, because on this model of fridge/freezer, the actual cooling starts from the freezer coil and ends in the fridge. Try to check the thermocouple first. Also be sure there is nothing obstructing the flame.

    Dometic Americana Freezer/Fridge not cooling

    The recall has nothing to do with your fridge not working. Your cooling unit has gone bad. And yes you can get a new fridge for a few hundred more than a new cooling unit. And sooner or later PPL motorhomes will run out of their cheap stock. The fridges they have are out of production. I know I am a Dometic dealer.
