I have a problem with my air conditioner fan not starting. As seen from the schematic below, when I test for voltage between the brown and black wires, I get 0 V (this is the problem). The indoor unit isn't sending the control signal to turn the fan on. The compressor powers on fine though. When I connect the brown and red wires together (since red is giving power fine), the circuit breaker trips, maybe too much inrush current since motor and compressor turn on together?
I then powered the fan separately and it works (fan or capacitor is not faulty).
- Could there be a relay or something controlling the fan that's not giving power from brown cable?
