Check that the fanmotor can spin freely. If not, can be caused by seized bearing on left side of fanblade, or foreign object, insect nest stuck in fanblade. If however it spins freely, check that fanmotor is being supplied with voltage (you sound technically capable of operating a volt meter). If power is supplied, fanmotor is faulty and needs replacing. If no voltage, problem lies with the pc board. If you know someone who is capable let them check the relays on the board. Also you can check that all plug on connectors are making good connection.

Hello Hamid,
The unit is designed to run the indoor fanmotors continuously when in cooling mode on both indoor units (evaporators). The reason is that this circulates the air and the temperature thermistor or sensor is able to sense return air temperature and in turn start or stop the outdoor unit and compressor as required according to the setpoint temperature. The reason for either unit not reaching setpoint temperature can be a couple of reasons. A) Incorrect design - the unit may be too small for the application. You can calculate this roughly at 650BTU per square meter of room in a relatively warm ambient climate. Or secondly B) The outdoor unit has leaked and is short of refrigerant. You can check this when the outdoor unit is running by feeling the thicker copper tube on the right hand side of the unit. This should be cool to cold. If no temperature difference is felt, it is short of refrigerant. Hope this helps you. Goodbye

you need to have the unit checked for the amount of freon in the system this must be done with a gauge set the freon amount is obviously incorrect
also the a-frame evaporator must be sealed in the furnace cabinet

SOURCE: A/C compressor fan won't turn on by itself.

How does changing the bossing of the fan fix the compressor to turn back on?
