Fridge issue: Cools on 12V not on propane

[Westy914]

Just back from 2000+ mile exploration of British Columbia. Fridge worked great on first portion of trip but after many miles on rocky, washboard roads my fridge stopped cooling on propane. It cooled very well on 12 volt (fins were frosty) but would not cool when switched to propane. It lit up fine every time but wouldn't cool. I know it was lit because the light on the display panel glowed, the flue vent got warm and I could hear the burner at the vent. Any ideas on what is wrong?

I have repaired and serviced many of these refrigerators. Have never experienced your symptoms, my guess is that your not waiting long enough for the unit to cool or your flame combustion box is dirty. With debris in the box the flame can burn and you will get heat but not enough.
I would suggest you remove refrigerator and service.

X2 on cleaning the jet. Good opportunity to clean everything and maybe add some more fans.

Good points. I did feel like the temp at the vent was a little less than usual. Thanks.

I’ll pull the fridge and clean things up.
