COMPONENT TESTING PROCEDURES
Regulating
Thermostat
resistance < 1Ω
(Electric & Gas)
If resistance is infinity, replace
Regulating Th ermostat.
Thermistor
resistance
40KΩ @
86°F
50KΩ @ 77°F
99KΩ @ 50°F
If resistance is infinity, replace the
Thermistor
Thermostat Thermal
cut-off resistance < 1Ω
(Electric models only)
If resistance is infinity,
replace Thermostat
Thermal cut-off.
Thermostat Hi-limit
resistance
< 1Ω
If resistance is infinity,
replace Thermostat
Hi-limit.
Heater resistance 20 Ω
If resistance is infinity,
replace Heater.
The power supply will be off if the temperature
is too high. Then we need to press this red
button on the thermostat to restart the dryer.
Measure resistance of the following terminals
(Electric & Gas):
1. Door switch: open
Terminal: “COM” – “NO” (1-2): ∞ Ω
2. Door switch push: On
Terminal: “COM” – “NO” (1-2): < 1Ω
Belt Safety Switch
(Electric & GAS)
- Lever open: Resistance value
< 1Ω
- Lever push: Resistance value:
∞ Ω
