| no fire in the burner
I have a Tempstar furnace with model no. ntgm075ega3. When I turned it on, the fan works, exhaust fan also works but the burner does not fire. I checked the wires from the circuit board going to the gas valve.
Black wire has 24 volts AC
Orange and the blue wire does not have any volts or power in it. Is this normal?
I also checked the wires from gas valve to the ignitor.
3 Wires
only one of the 2 blue wires has 24 volts AC
the black one does not have any voltage. Is this also normal?
Please help me what to do next. |
