Dometic RM66E not cycling on gas
Hi all...my Dometic RM66E refer (circa 1978, Class C) works fine on shore power - cools nicely and maintains temperature based on the electric thermostat setting. When running on propane it also cools well - too well in fact, because it disregards the gas thermostat setting and runs continuously. After a day or two it gets down to about 20 degrees in the fridge area.
I would be ok turning the gas on and off every day as a workaround except that the unit's piezoelectric starter is also non-functional, so solo starting is a bit of a circus act involving a bent fork (to hold the pilot gas valve open), running out of the cabin, and 2 or 3 vigorous "pops" of the accumulated gas before the pilot will light without blowing itself out. Arguably this is a part of the camping experience that could benefit from less excitement.
I did manage to find the original schematic for the refer, and more or less understand the various parts and how they work, though my experience with gas plumbing in general and rv refers in particular is limited. Wondering if anyone has had this issue and/or is familiar enough with this or similar units to advise on a reasonable troubleshooting procedure and possible DIY repair options. I checked into professional repair and new/used replacement options and they are all prohibitively expensive, so if it's not possible to fix it I'll keep on doing what I've been doing.
Thanks in advance for any ideas!
