Heater Switch Test - Electric Type

Caution

Trouble Symptom

Measurement Condition

Before measuring resistance, be sure to turn power off, and do voltage discharge.

(When discharging, contact the metal plug of power cord with earth line.)

While operating, heating will not work.

Drying time takes longer.

After turning power off, measure the resistance.

Check controller.

Check Harness-linking connector.

Check motor. Check if the value of measured

resistance is below 1

Ω

between terminal

and

at RUN condition.

YES

•

Check motor and

replace it.

1. Is resistance between heater terminal

and

below 18 ~ 22

Ω

2. Is resistance between heater terminal

and

below 18 ~ 22

Ω

3. Is resistance between heater terminal

and

below 9 ~ 11

Ω

YES

•

Replace heater.

Check if the value of measured resistance is

below 1

Ω

between terminal TH2 (Safety thermostat).

YES

•

Replace TH2

(Safety

thermostat) and

TH3 (Hi-Limit

thermostat)

Check if the value of measured resistance is below

Ω

between terminal TH3 (HI-Limit thermostat).

YES

•

Replace TH2

(Safety

thermostat) and

TH3 (Hi-Limit

thermostat)
