A Reefer story and temp adjustment oddity

In preparation for our 1st upcoming trip, fired up the Reefer yesterday in our 96LY30; the original a Dometic model.
Worked great on electric, failed on propane. The dreaded "Check" light. Cycled it a few times, nuttin.
Pulled the plastic coach-side access, pulled the 1st metal wind shield panel, tried it again. Got a cool little orange fireball! Whoa. Turned it off, tried again, another cool little orange fireball. Pretty cool, as long as your face is not in close looking to see if there is a flame...

Anyhow, figured it was a buggered jet or burner. Pulled a bunch of screws and bent some metal, and the orifice was plugged maybe 50%. Figured that it was not enough propane coming out to light, but once it built up, it ignited the cloud that formed. Cleaned it with some carb cleaner, removed a bit of soot/rust on the burner, de-rusted the igniter and the thermocouple, re-assembled, and it fired right up. Great.

Set it on #5 (max cool), and at the end of the day (yes, the coach is level)the freezer was 20 and the fridge was 40. Great, no need to keep putzing with this... I thought.

Then I set the temp down to #4. After 4 hours the freezer was 15...and the fridge was 60. ???

Set it back to #5, and after another 4 hours the freezer was about 12, and the fridge was 62.

Dang it. Turned it all off and let it set for 4 hours. Turned it on electric just before I went to bed, and 8 hours later the freezer is -2 and the fridge is 40. Heck, this works better than our house unit!

Just now put it back on propane, and left it on #5.

Any ideas on why setting it down (from #5 to #4) would have such an effect? At this point I assume there is a bad switch (Note to self - don't use setting #4) or ???

Figured I'd do an update before we hit the road...

Left it on propane all night, and were back to 15F Freezer and 40F in the reefer. So whatever the issue, it resolved itself.

But I ain't touching the thermostat again; it will stay on 5 for the duration of the trip...

I got the same frig and it runs very cold. When traveling it constantly switches from 12v to AC and sometimes to gas. Temp in frig stays around 40 going down the road with selector on #3. Sometime I will turn it up higher if its on 12v.

Problem is when I am hooked up at campsite. Its gets really cold and everything in frig will freeze and freezer looks like a huge block of ice. Because I am now full-timing, keep it set on #1 and a few times simply cut it off at night and back on in AM. For a 19 year old frig I am not complaining as long as its working.

Never have gotten the ice maker to work and appears it was never used. Water line is not blocked so figure its the ice maker itself. Another project for another day
