LP Gas pressure at refrigerator
I've been trying to troubleshoot why my refrigerator does not work on propane: no spark, no flame. In order to test the propane, I removed the test port plug in the propane supply line at the fridge...

The model is supposedly "german": RML8555. The components of the system don't match old-biscuit's diagram. (Although I've had other RV's that essentially match that layout.) It's an unusual system. The only "test port" is actually BEFORE any other components. It appears not to have a solenoid. There is a "gas control valve". ajriding ... I'll try what you suggested tomorrow. I have confirmed that there is 12 volts coming to the system. The fridge is a 3-way, and it works well on both 110 and 12v.
YES that is a totally different control scheme
It is a Dometic 8 Series (RML8555)
Gas Valves are dual serial gas modules that use Very Low Voltage (less then 1.5V)
Each valve has a test point to measure voltage and resistance (28.5 ohms)
See pg 47
Burner Control Module provides Igntion source and flame proving signal (separate spark electrode & flame ionization probe)
Also has Test points for measuring voltage
See pg 48
