40 gallon gas with a vent motor FGR
the thermocouple screws into a factory interrupt switch
that connects to two limit switches on the top flue vent opening
I have continuity through the wire and both limit swiches, but
when i connect the limits back into the switch the pilot does not stay lit
If I jump out the switch the PILOT will stay on
Can it be a weak thermocouple that does not
generate enough current to travel through the limits?
The pressure swich is working and it energizes the vent motor when
the burner lights
