Fixing LG Air Conditioner Error Code E1 or CH02 – Indoor Unit Thermistor Issues

Caught an E1 or CH02 error on your LG air conditioner? It’s not the end of the world!

Your indoor unit’s thermistor, a tiny temperature-checking sensor, may be playing truant. It could be damaged or disconnected.

But how to fix it? Easy, my friend!

  1. Phase one – Power off your air conditioner and unplug it. Safety first!
  2. Peel off the indoor unit’s front cover—nothing hard, really.
