But the mag field is still high because the current goes up, More Power. In theory.
The amount of turns and gauge of wire is what sets the operating voltage range.
That Gas coil may have a limit resistor in series with it. And probable is encapsulated.
Theory only works perfect in a vacuum.
BTW, I keep repeating that the solenoid is replaceable and simply screws into the gas valve.
Supposedly, at long last, they are mailing me out a replacement. Hopefully, I'll get it by Christmas.
I am having the exact same problem with what sounds like the exact same unit. Jumping the wires with the 9V, I can switch the main burner on and off. However, I believe my remote receiver unit may be completely fried, as it is no longer making any beeping, even when using the "learn" button. It is also not able to turn the burner off (not sure from your description if yours was able to or not). Did you see the same result (no beeping) from your unit while the solenoid was busted?
Also, any tips dealing with ProCom on getting the parts replaced under warranty? Was the solenoid the fix and as easy as it sounds? This unit was already installed in the house that I bought, so I don't have a receipt.
There was always beeping coming from the old receiver, and it always was able to turn off the gas valve, since that required less voltage.
ProCom sent me a new remote receiver and solenoid. I replaced the receiver first and it worked just fine, so I just kept the solenoid as a spare.
