......Can it be bypassed by installing a 34k resistor?
I had to go back on a no hot water call for a GPVH 50-100 AO Smith pwr vent WH. The "very hot" and the green "vacation" status lights were lite up but of course the WH inducer was not atctivating.
I went thru the reset procedure but the WH remained in lockout.
I measured the fume senor resistance at 35k ohms. Should have been good but WH still would not fire. I thought there something I was overlooking but factory tech said if the sensor ohmed out OK then I had to change the Valve/thermostat.
I changed both and got the WH back on line.
There are a lot of ceramic paints(Not flameable) in the basement so I am wondering if they are affecting the sensor is it possible to replace sensor with a 35k ohm resistor to avoid nusiance sensor trips?
I am assuming I am not the only one who has wondered about this.
