" Refrigerant Overcharged
RXYMQ36 · 48PVJU
Excessive charging of refrigerant is detected by using the outside air temperature, heat exchanging
deicer temperature and liquid pipe temperature during a check run.
When the amount of refrigerant (calculated by using the outside air temperature), heat exchanging
deicer temperature, and liquid pipe temperature exceed the standard during a check run.
Misalignment of the outside air thermistor
Misalignment of the heat exchanging deicer thermistor
Misalignment of the liquid pipe thermistor
Be sure to turn off the power switch before connecting or disconnecting the connector, or parts may be damaged.
Check the mounting condition of the
temperature sensors of the outside air
thermistor, heat exchanging deicer
thermistor, and liquid pipe thermistor
in the piping.

Remove the outside air thermistor,
heat exchanging deicer thermistor,
and the liquid pipe thermistor from the
outdoor PCB and measure resistance
with a tester.
