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 outside panel, and connected a water column manometer. When I turn open the propane valve, the gas comes into the manometer and just gurgles right through! Should I assume this means that the gas pressure to the fridge is too high (supposed to be 11 inches on manometer)? The stove burners work fine, and the propane funace works fine.
You have couple of issues:
No Spark/No FLame
Circuit Board sends 12VDC to gas valve and spark electrode at same time
Gas valve TEST port is downstream of gas valve/solenoid so it must be opening if you have gas flow thru manometer.
No Spark......
Circuit board sends 12VDC from transformer to electrode when gas valve is opening.
Spark gap too narrow/too wide ---no spark (1/8" - 3/16") centered directly over burner slots
Electrode wire connection clean/tight at transformer
Manometer....tubing in 'U' shape. One end Open/other end connected to gas test port. Water in tubing.
11" WC is only 0.4 psi so it should NOT gurgle THRU
