I have a 7 cuft dometic fridge and it heats up when traveling anyone have any ideas on why this could be happening, freezer seems cold but temp gauge for fridge goes up when driving does not seem cold at all

Don't know it is electronic ignition so when you stop it must relight itself because if I am stopped the fridge starts to cool down at night the other night it went from 50 to 32 in the morning then traveling it went up to 54

Have you checked the settings, auto vs manual on the fridge? If it goes out while you are traveling the flame may be going out. Are all the plates in their correct position? If it is a three way fridge, are you plugging in at night? Is there enough propane in the tank?Good luck,Harry

Sounds like the flame is blowing out when moving. Try wrapping some tin foil around the outside of the burner area to block the wind. Is there a plug in the end of the drain tube?

I have the same problem with my Dometic. Traced the problem to the installation wherein the fridge is mounted right on the floor of the rv directly above the catalytic converter. I've checked the temperature of the floor adjacent to the fridge and it's 104 degrees Fahrenheit. I've thought long and hard for a solution but have come up empty. Can't raise the fridge because the sink is in the way. Can't insulate the floor because there's no room under the floor of the fridge and the heat shield of the catalytic converter is too close to the floor. Oh well, I'll just have to live with it.

Yeah.. I misread the OP "don't know it is.. " . as "don't know if it is..".

I know it's DSI.

no I'm not on battery power and the upgraded fridge to a 7cu ft is only a 2 way

Pilot lights don't light themselves.

It's not a pilot light it is the burner, small burner but still THE BURNER

And yes it's electronic ignition, turn on the control it lights, if it blows out it Will try to relight

The temp in my Dometic would rise while driving (running on LP) and then cool properly at night (120vac shore power). Found the LP pressure was too low AFTER the usual cleaning of the gas jet, burner, and vent tube. Never got a "check" light on gas but the flame was just a bit bigger with a good regulator.

Livin Lite advertises the fridge as a three way. Are you operating it on battery power when traveling?

A common reason for temp RISE in transit is the drain tube system for the evap fins. Norcolds have a check valve, while Dometics have a plastic drain hose. That hose should be looped or given a p trap when installed but no OEM ever does that. I would block off the end of the drain tube and check the temp rise on next travel. IF the flame went out in transit, he would have a check light indication. It seems he does not have that problem. Doug

The OP's TC is a 2015 and prolly warrantied. The Mfg. should have a fix.

OPs rig doesn't HAVE a pilot light. It has only an automatic electronic sparker.

And it does sound as though the fire blows out when you are traveling. I think I'd inspect the burner and fire tube. They aren't supposed to blow out that way. Might be something obstructing things.
