Fridge not staying lit when traveling

Clean the burner.

My set up is similar but there is another approximately 10 X 10 sheet metal wind deflector covering the burner area. It covers from the bottom of the compartment up to where the flue goes above the access door and from the right wall to approximately the middle of the access door opening.

Even with this additional protection my frig will blow out if the wind is strong enough from some directions, I check it at every stop on high wind days.

I don't know what kind of fridge you have but if it's a dometic you can get a free baffle kit. We got a kit a couple of years ago. If I remember I think our rv dealer had to order it but it was free and it came with baffles and a burner shield.

Sure its not staying lit? Or you might have a low house battery.

These fridge's thermostats use DC. The fridge will start up just fine, but when it shuts off when it reaches its temp it will not start back up again if you have a low battery situation.

They make a "kit" which is a piece of sheet metal that protects the flame. Look up your fridge and search for it. I had to install that on my Fleetwood. The Sunnybrook doesnt seem to have that issue.

Warming up while traveling can be hot air going up the white drain line, not the burner going out. It should have a check valve/plug in the end. You could also fill the black pan half full of water so air cannot get in on your next trip and see what happens.

Had the same problem on previous MH. Worked fine when parked, gas check light would come on when traveling. Cleaned all the rust out of the burner assembly and no more problems.

And, this brings up an interesting question:

Is it safe to use your refrigerator on propane while traveling? To be honest, I've never given it a second thought. If the RVIA thought that it was unsafe to operate it on propane while en route, I'm sure there would be warnings, cautions and interlocks to prevent it. I was just wondering because I saw a YouTube video the other day where some "Mr. Professional Firefighter Dude and RV guy" thought it was the most dangerous thing in the world to do. He went on whining about how you would be putting firefighters lives in danger, etc. What a crock. As a trained member of an industrial fire brigade unit at a power plant, we train on LPG fires (BLEVE's) since there are so many propane powered devices in use these days. Even the comments were humorous - blasting those of us carelessly endangering the lives of all those unknowing folks out there on the highways of our fine country.

Oops, I guess I let my position on the subject kinda' slip out. And yes, I do turn it off before hitting the fuel islands at the Flying J/Pilot and other gasoline dispensing sites.

I have the same Norcold fridge and was having the same issue. Not staying lite will traveling and recently randomly failing to relight while parked.

I removed the nozzle and soaked in carb cleaner and used compressed air to clean out. Reassembled and flame looked better than before but still had random ignition issues. Disassembled again and an inspection of the ignitor revealed a hairline crack on the porcelain.

Replaced the ignitor and reassembled burner assembly. Success

A simple replacement and cost of new ignitor was less than $20.

it looks super clean in there, check and see if while cleaning you didn't knock the flame sensor a little out of normal range making it overly sensitive.
