Usually a single-phase asynchronous motor with two windings (start and run).
Helps kickstart the motor and protects it from overheating or power surges.
enters through the thermostat , which acts as the primary gatekeeper.
The relay briefly engages the of the compressor motor until it reaches speed, then switches over to the running winding .
A separate parallel circuit powers the via the door switch, ensuring the light works even if the compressor is idle. Common Troubleshooting Steps
