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 1Ω between terminal
and at RUN condition.
YES
NO
• Check motor and
replace it.
1. Is resistance between heater terminal
and below 18 ~ 22Ω?
2. Is resistance between heater terminal
and below 18 ~ 22Ω?
3. Is resistance between heater terminal
and below 9 ~ 11Ω?
YES
NO
• Replace heater.
Check if the value of measured resistance is
below 1Ω between terminal TH2 (Safety thermostat).
YES
NO
• Replace TH2
(Safety
thermostat) and
TH3 (Hi-Limit
thermostat)
Check if the value of measured resistance is below
1Ω between terminal TH3 (HI-Limit thermostat).
YES
NO
• Replace TH2
(Safety
thermostat) and
TH3 (Hi-Limit
thermostat)
