Possible Causes

Overheating compressor, Faulty overload protector, Erratic temperature sensor, Control board logic fault

Safety First: Unplug before accessing compressor or sensors.

Steps:

Improve cooling: Clean condenser and ensure fan operation to reduce compressor temperature.
Check overload: Inspect the compressor overload protector; replace if it trips at normal temperatures.
Test sensors: Verify thermistors are within spec and replace any that are erratic.
Control board: If short cycling persists, the main control PCB may be defective.
