Anyone experience with Tekion units?

Good evening all.

Could anyone possibly help me with finding error codes for Tekion AC units. The specific unit is a Tekion 9000S. The error code displaying is an E3.

Any help is much appreciated thanks.

E3 is indoor coil sensor error. The sensors are soldered directly to the pcb and can't be swapped. You have to either cut the wires and join a new sensor or unsolder the original one. I would cut the wires first as it was quite common to be a PCB fault.
