What Does Error E2 Mean?

The E2 error code on White Westinghouse Air Conditioners indicates a malfunction in the indoor temperature sensor, which can lead to erratic temperature readings and inconsistent cooling. When this error occurs, the cooling function may stop while the fan continues to operate, and the compressor may cycle off quickly or fail to run altogether. This issue is typically caused by a fault in the evaporator coil temperature sensor or thermistor.

Common Symptoms:

  • Cooling function stops while fan may continue running
  • Compressor may cycle off quickly or fail to run (as per Westinghouse error code behavior for E2)

Possible Causes

  • Evaporator coil temperature sensor fault or thermistor anomaly (medium)

How to Fix Error E2

DIY Fix Basic power reset and filter check

  1. Turn off the air conditioner using the remote or main switch.
  2. Disconnect the unit from power at the breaker or plug.
  3. Wait approximately 10 minutes to allow the system to reset.
  4. Reconnect power and restart the unit.
  5. Check and clean the air filters; ensure they are properly installed.

Technician Only Inspect and replace temperature sensor/thermistor

  1. Disconnect unit from power and safely access the indoor unit control compartment.
  2. Locate the evaporator coil temperature sensor / thermistor wiring and connections.
  3. Measure the sensor resistance against manufacturer specifications using a multimeter.
  4. Replace the sensor if readings are outside normal ranges or if the sensor is damaged.
  5. Verify proper seating and connection of sensor to the control board, then test operation.

Parts needed: Evaporator coil temperature sensor / thermistor, Multimeter (for diagnostics)

🛑 When to Call a Pro:
  • If error persists after basic power reset and filter cleaning
  • If user is uncomfortable or inexperienced with sensor diagnosis
  • If sensor continuity checks show open/short circuits
