Heating problem


Anyone please advise me on what to do. I have a Goodman HVAC that is almost 4 years old. You can hear the thermostat click on when you turn it to heat and then a humming sound but the fan does not turn on. It will turn on if you switch it from auto to on. Steps I have taken.

1. Reset the thermostat and waited 5 mins
2. Turned main breakers to furnace off then back on.
3. Unplugged unit and plugged back in (It started to work for about 10 mins then tunred off)

Heating problem


if your cold set the stat to FAN/ON and set the heating to your desired temp...if the heating runs with the fan in on the relay on the control board might be shot or the motor winding for th eheating side...do you have an Induced Draft motor mounted above the burner and control board?

Heating problem


I'm sure if I have an induced draft motor. When I took off the two panels on my left I had a circuit board with a fan behind the circuit board and on the right side I had a burner next to a blower. The heater is now working. Not sure why though. All I did was check wire connections and the fuse. I kept depressing the safety switch that the kills the power once the panels are off. The blower would work and I could hear clicking from the circuit board but the burner would not light and the fan would not come on. After messing with wires and safety switch evenutaly everything started working.
