*P3
1) In heating mode, when the outdoor temperature is lower than
-13 F(
-25
℃
)
for 1 hour, the
indoor unit display error code P3.
2) If the outdoor temperature is higher than
-8 F(
-22
℃
)
for 10 minutes and compressor stop for 1
hour or outdoor temperature is higher than
23 F(
-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 controll
. 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.
