Compressor Start Relay / Overload Kit
The PTC start relay uses a ceramic thermistor to briefly engage the compressor's start winding. Over time, thermal fatigue causes the ceramic to crack or lose conductivity, preventing the torque required to rotate the motor from a standstill. This part contains the specific electromechanical components to restore the starting circuit's integrity.

Compressor Run Capacitor
The capacitor provides the necessary phase shift to maintain the magnetic field in the motor windings. If the dielectric material degrades or the internal pressure relief opens, the motor will lack the electrical 'push' needed to transition from static to dynamic state, causing the compressor to fail to start.

Main Electronic Control Board
The control board acts as the logic gate for the cooling cycle. If the onboard relay responsible for compressor power delivery develops pitted contacts or a failed solder joint, the compressor never receives the 120V signal to begin the start sequence, resulting in a unit that remains electrically inert despite thermostat demands.
