Question about Mitsubishi Mr. Slim MXZ30TN Air Conditioner
This must be a 3 phase compressor.If one of the 3 hot wires is reversed to the compressor,then yes it can make the unit run in reverse.
What will happen is that any oil will be taken out of the compressor and forced into the system causing the compressor to burn up.
Another possibility is if one hot wire went to ground this would cause something called single phasing.Say the compressor needs 220 volts to run and you take half of that away,leaving it with 120 volts.The compressor will draw more amps and burn up.
What i dont understand is there should be fuses and pressure switches to protect the compressor from damage.
So yes it is possible if a sensor went to ground to do serious damage.
