What Does Error E2 Mean?
The E2 error code on Whirlpool air conditioners indicates a malfunction in the indoor temperature sensor, which may lead to inaccurate temperature readings or the unit failing to cool effectively. This error can also trigger a protective shutdown to prevent freezing or damage to the system. Addressing this issue typically involves inspecting and possibly replacing the temperature sensor or ensuring proper airflow and connections.
Common Symptoms:
- Unit displays E2 and stops cooling
- Abnormal temperature regulation detected
- Possible protective shutdown to prevent freeze or damage
Possible Causes
- Indoor/evaporator temperature sensor malfunction (medium)
- Protective anti‑freeze/protection mode triggered by abnormal coil/evaporator conditions (medium)
How to Fix Error E2
DIY Fix Basic Troubleshooting Steps
- Turn off the AC and disconnect power for a few minutes to reset control logic
- Clean/replace air filters to ensure proper airflow
- Check that indoor unit sensors and visible wiring/connectors are securely connected
Technician Only Sensor and Control Inspection
- Test indoor/evaporator temperature sensors (thermistors) with a multimeter
- Inspect wiring harnesses for open/short circuits
- If sensor faults confirmed, replace the faulty temperature sensor
- Verify that protective anti‑freeze conditions are not caused by refrigerant or airflow problems
Parts needed: Temperature sensor (thermistor), Wiring harness, Control board (if diagnosing communication faults)
- If sensor replacement does not clear error
- If wiring inspection reveals damage or refrigerant/coil frost issues
