Compressor temperature thermistor

"Protection stop by
"compressor temperature 110°C during compressor operation""
generated 2 times within 24 hours.

Check Point 1 : Check if 3-way valve(gas side) is open.

Compressor thermistor characteristics check
(Check by disconnecting thermistor from PCB.)

* For the characteristics of the thermistor,
refer to the APPENDING DATA (Chapter 3).

Check Point 4 : Check the compressor thermistor

EEV open?
Strainer clogging check
(Refer to PARTS INFORMATION 3)

Check Point 3 : Check the outdoor unit fan,heat exchanger

Check for foreign object at heat exchanger

Check if fan can be rotated by hand.

Motor check (PARTS INFORMATION 5)

Check Point 2 : Check the EEV, strainer

Check Point 5 : Check the refrigerant amount

Leak check

EEV open?
Strainer clogging check
(Refer to PARTS INFORMATION 3)

Check Point 2 : Check the EEV, strainer

If the 3-way valve(gas side) was closed, open the
3-way valve(gas side) and check operation.

02-24

Check Point 1 : Check if 2-way valve(liquid side) is open.

If the 2-way valve(liquid side) was closed, open the
2-way valve(liquid side) and check operation.
