Customer Question

I have a Haier A/C showing an E1 error. I've checked the room temperature sensor - around 4 K ohms, made sure all the buttons were not stuck; unplugged then plugged in WHILE holding the power button.

Customer: The only thing I don't really know is the resistance of the air sensor,
