HIGH-LIMIT THERMOSTAT, INLET
THERMISTOR, & THERMAL CUTOFF
(ELECTRIC MODELS ONLY)
Refer to page 4-10 for the procedure for ac-
cessing the high-limit thermostat, inlet therm
-
istor, & thermal cutoff.
1. Unplug dryer or disconnect power.
2. Disconnect the wires or connector from
the component under test.
3. Set the ohmmeter to the R x 1 scale.
4. Touch the ohmmeter test leads to the
high-limit thermostat terminals. The me
-
ter should indicate a closed circuit (0 Ω).
NOTE: The thermostat opens at 295°F
(146°C).
5. Touch the ohmmeter test leads to the
thermal cutoff (TCO) terminals. The me
-
ter should indicate a closed circuit (0 Ω).
NOTE: The TCO opens at 352
°F (178°C).
6. Set the ohmmeter to the R x 100K scale.
7. Touch the ohmmeter test leads to the inlet
thermistor terminals. The meter should in
-
dicate approximately 50k Ω @ 69 to 86
°F
(21 to 30
°C).

3. Set the ohmmeter to the R x 1 scale.
4. Touch the ohmmeter test leads to the heat-
er terminals. The meter should indicate be

Electrical Shock Hazard
Disconnect power before servicing.
Replace all parts and panels before operating.
Failure to do so can result in death or electrical shock.
