Initiating troubleshooting
3. Failure phenomenon: The compressor will not run.
Is the "timer lamp" (orange) of the indoor unit

Yes
Yes

unit blink once or become turned off?
Check for failures according to the self-
diagnosis display.
Remove the connector (CN4) of the room
temperature thermistor and heat exchanger
thermistor and measure the thermistor resistance.
Did the reading roughly agree with the resistance
values indicated in the right-hand figure?
Replace the "room temperature and heat
exchanger thermistors".
Thermistor characteristics (resistance)
