What is the E2 Error Code?
The E2 error code is typically associated with a malfunction in the air conditioner’s indoor unit. It indicates a communication error between the indoor and outdoor units or a fault in the internal components of the indoor unit itself.
Possible Causes of the E2 Error Code
There are several possible causes for the E2 error code in an air conditioner:
