Thermistor or Related Abnormality (Indoor Unit)

Remote
Controller
Display

Method of
Malfunction
Detection

The temperatures detected by the thermistors are used to determine thermistor errors.

Malfunction
Decision
Conditions

When the thermistor input is more than 4.96 V or less than 0.04 V during compressor
operation

∗

(reference)

When above about 212°C (less than 120 ohms) or below about -50°C (more than 1,860 kohms).

Note:

The values vary slightly in some models.

Supposed
Causes

Faulty connector connection

Faulty thermistor

Faulty PCB

Troubleshooting

Check No.06

Refer to P.279

: Heat exchanger temperature thermistor

: Room temperature thermistor

Check the connector connection.

YES

Correct the connection.

Replace the thermistor.
(Replace the indoor unit PCB.)

Replace the indoor unit PCB.

Is it normal?

(R4696)

Check No. 06

Thermistor resistance check

YES

Caution

Be sure to turn off power switch before connect or disconnect connector,
or parts damage may be occurred.
