Blower will not come on with A/C
The blower will not come on when A/C is set to on. The compressor runs and I hear clicks from the relays but nothing happens. I jumpered the motor and it ran fine (it is bran new). By the way, the heater works just fine. I discovered a possibly burnt out diode with a 37 on it. Could this be the problem or simply a symptom of something larger?
This is a Lennox heat pump hybrid M/N 80MGF 3/4-100A-5 single phase 13 years old with new compressor unit outside and new blower motor.
Pic attached of possible burnt diode on control board.
Thank you in advance,
