Service Diagnosis

4.11 Four Way Valve Abnormality

Remote Control 
Display

EA

Method of 
Malfunction 
Detection

The indoor air temperature thermistor, the indoor unit heat exchanger thermistor, the outdoor 
temperature thermistor and the outdoor unit heat exchanger thermistor are checked to see if 
they function within their normal ranges in the operating mode.

Malfunction 
Decision 
Conditions

A following condition continues over 10 minute after operating 5 minutes.

„

Cooling / dry operation
(room temp. – indoor heat exchanger temp.) < –5°C

„

Heating
(indoor unit heat exchanger temp. – room temp.) < –5°C

Supposed 
Causes

„

Connector in poor contact

„

Thermistor defective

„

Outdoor unit PCB defective

„

Four way valve coil or harness defective

„

Four way valve defective

„

Foreign substance mixed in refrigerant
