Dometic RM3604 LP not re-igniting
Hello, I have an old Lance camper with a Dometic RM3604 refrigerator. I’ve sort of refurbished the refrigerator and got it back up and running on AC and LP, but recently it’s started having an issue...

I bought a manometer and measured my LP gas pressure at the refrigerator gas solenoid (it had a test port plug I was able to remove and install the manometer fitting). Turns out my gas pressure was only 10inH20, but the service manual for the Dometic said to not let it drop below 11.
I had recently installed a new propane regulator in the RV and wasn’t aware that the gas pressure could be adjusted. I fine tuned it with an adjustment screw on the regulator and now my pressure is at 11.5inH20. Fridge ran for 12 hours straight without shutting off, so it looks like it’s fixed!

I doubt 1 inch will make much difference. The OEM boards from this era were pretty crappy. I went through all the steps you did, with much frustration. The Dino board was an easy replacement, and lasted years until I sold my old camper. Learned about it from RV.net.
I see some cheap ones available new on Ebay.
