Heater switch test - Electric Type
Trouble Symptom
Measurement Condition
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
①
and
⑩
at RUN condition.
YES
NO
• Check motor and
replace it.
1. Is resistance between heater terminal
①
and
②
below 18 ~ 22
Ω
?
2. Is resistance between heater terminal
①
and
③
below 18 ~ 22
Ω
?
3. Is resistance between heater terminal
②
and
③
below 9 ~ 11
Ω
?
YES
NO
• Replace heater.
Check if the value of measured resistance is
below 1
Ω
between terminal TH2 (Safety Thermostat).
YES
NO
• Replace TH2
(Safety Thermostat).
Check if the value of measured resistance is below
1
Ω
between terminal TH3 (HI-Limit Thermostat).
YES
NO
• Replace TH3
(HI-Limit Thermostat).
TH3
①
②
③
TH2
WARNING
• Before measuring resistance, be sure to turn power off, and do voltage discharge. (When discharging,
contact the metal plug of power cord with the ground)
• Failure to follow these instructions can result in death or electrical shock.
