I am a bit lost... my last one (back before the dawn of time) had a pilot light! The fridge works fine on AC. Refused to start on propane. Gives a 'F' code (as in U R F-ed). I was able to "fire it up" with a grill lighter... and it kept cold for 24-48 hours. Once I saw a C before the F codes. When trying to start on propane I can hear a clicking at the back in the access hatch. Does anybody know these units?

Yes I do... Open up the exterior access panel and look inside the burner area. You'll see the spark electrode inside the burner chamber this electrode does 2 things ignites the gas to light the flame but also tells the computer if the flame has blown out or not ignited. So I would clean the ignitor carefully and clean the burner base so the arc will jump to the burner to light and also be sure the flame touching the electrode. As for the C it means the DC battery is too low.
