*P3
1) In heating mode, when the outdoor temperature is lower than -25℃ for 1 hour, the indoor unit
display error code P3.
2) If the outdoor temperature is higher than -22℃ for 10 minutes and compressor stop for 1 hour or
outdoor temperature is higher than -5℃ for 10 minutes, then the unit will return to work.
* Fault Symptom: The display board shows a garbled code or a code that is not an error code found
in the service manual nor a temperature reading.
Trouble shooting:
Use the remote controller. If the unit does not respond to the remote, the indoor PCB needs to be
replaced; if the unit does respond, then the display board needs to be replaced.
