Re: Elec Burning Smell Around Thomas Aux Compressor
Reply #1 –
The wire which is overheating is obviously the power (+) wire for the motor. A wire overheats when it is passing more current than it is designed to handle. If the motor is binding or seizing or turning against excessive resistance it will draw more amps than normal, which will overheat the power wire. Possibly the bearings are going out on motor or compressor is failing?
The item you have circled in red looks like a relay in the motor power circuit, which is controlled (opened or closed) by the wire coming from the pressure switch.
