Possible Causes
Dirty coils causing high pressure, Failing fan motor reducing airflow, Faulty high-temperature sensor or overload, Incorrect humidity sensor readings
How to Fix / Troubleshooting
Safety: Unplug before cleaning or accessing internal parts.
Steps to address short cycling:
- Clean filter and coils: Ensure the air filter, evaporator, and condenser coils are clean to allow proper heat exchange.
- Check fan performance: Verify the fan runs continuously and at full speed while the compressor is on. Replace the fan motor if it is slow or intermittent.
- Inspect high-temp sensor/overload: A weak thermal protector may trip too early. Test and replace with a Whirlpool-rated part if it opens at normal operating temperatures.
- Humidity sensor check: If the unit thinks the set humidity is reached too quickly, it may shut off prematurely. Test and replace the humidity sensor if readings are inaccurate.
Test: After cleaning and any part replacement, run the unit for at least an hour and confirm it maintains steady operation without frequent cycling.
