Refrigerator keeps shutting off on propane

[Ricgoc]

I have a small 2007 surveyor with a Dometic fridge. Runs great on AC. When dry camping and running on propane, seems to run fine for first few hours, then check light comes on. Relights after a while, then have the same issue repeatedly. No issues with gas cooktop or water heater. Thank you.

Check the fuse on the outside of the camper. It is a 15amp glass tube fuse. I replaced mine because the check light was always coming on and now fridge works fine.

What do the inside temperatures do?

A R/V refrigerator running on propane doesn't run constantly. The burner cycles on and off as necessary. How is your battery voltage?

What's the model of the fridge?

The Check light means it tried to light and didn't (or didn't sense that it had). It could be an issue with the flame sensor or a problem with the control board. I'd start by unplugging the connectors on the board and cleaning them up and see if that fixes your problem.

Mine did this once while driving. Unfortunately, the stock Dometic circuit board gives up early and sets the check light. The Dinosaur board keeps trying for a little longer. It also supposedly has a better thermocouple circuit. Even though mine works fine right now, I may switch to the Dinosaur board anyway.

Check the fuse on the outside of the camper where the fridge is.

Dometic refrigerators have your symptoms starting at about 3000 feet. It in the owners manual. I understand some people have corrected this problem by increasing the propane pressure to 13 in. WC from 11 in. WC. The check light comes on after three tries at lighting the burner. I wish for my old refrigerator that had a pilot for the cooling circuit. It worked everywhere I wanted to go.

Dinosaur board? Does this have another name?

I believe I have the same frig/frez, but haven't had a problem, yet.
Thanks for your time, Paul

pull the igniter and clean it off first . could be carboned up a bit . also check the electrial connections and make sure there tight and clean

If the fuse was blown it would never relight, which apparently it does from time to time. Now, it could be that the fuse holder is loose and makes contact sometimes, but that would be pretty odd.

Review the Reefer owner's manual for maintenance procedures. Fairly easy DIY job.

My problem was placement of the temp.sensor probe in relation to the flame. If it's not right close in the flame it will cycle right off then fire up again. I carry a manometer and we have bumped up pressure to increase the flame and thus improve cooling for several units but never got a gas light coming on from insufficient flame/cooling.

My dometic works fine up to 11,000 feet without any adjustments on propane.

Only thing I had to do is install a snip the tip thermistor and install 4 CPU cooling fans in the vent exhaust to improve cooling when temps are above 85 degrees. Works better than expected and fridge stays a pretty steady 37 deg F setting with only a couple of degree fluctuation during the day.
