Possible Causes

Faulty thermistor readings, intermittent power supply, overheating condenser, defective main control board

Safety: Disconnect power before accessing controls.

Check ventilation: Ensure vents are not blocked and the condenser is clean to prevent overheating.
Inspect power cord and outlet: Look for loose plugs or intermittent power (test with a meter).
Test thermistors: Check all accessible temperature sensors for proper resistance values. Replace any that are out of spec.
Control board: If sensors and power are good, but cycling remains erratic, the main control board may need replacement.
