  1. Turn off the air conditioner and wait about 10 minutes to see if the error clears (Electrolux official recommendation)
  2. Disconnect power fully and reconnect to reset the system
  3. After reset, attempt normal operation to see if the E1 code has cleared

DIY Fix Check basic accessible components

  1. Ensure the air intake and filters are clean and free of debris
  2. Visually inspect accessible wiring for signs of damage or loose connections (indoor unit)

Technician Only Inspect communication wiring and sensors

  1. Isolate unit power and inspect communication wiring between indoor and outdoor units for continuity and secure connections
  2. Test indoor temperature sensors and thermistors for correct resistance values
  3. Check for faults in communication circuits possibly on control boards

Parts needed: communication harness, thermistor sensors, control board
