What should I do if my TCL TAC-09CHSA/F6 displays E1 or E2?

If your TCL Air Conditioner is showing an E1 or E2 error, it could be due to several reasons: * The sensor connection terminal might be loose or not plugged in. Check the connector of the sensor and slot (CN6) and reconnect if necessary. * The room temperature sensor (IRT) or indoor pipe (coil) temperature sensor (IPT) might be damaged (short or broken). Check the resistance of the sensor R (25?) =5 k?, and replace it if it's shorted or broken. * The PCB might be failing. In this case, replace the indoor main PCB.
