THERMAL CUTOFF
(ELECTRIC DRYERS ONLY)
Refer to page 4-10 for the procedure for ser-
vicing the thermal cutoff.
The thermal cutoff is a non-resettable device.
The cutoff temperature is 178°C (352°F).
If the dryer does not heat and there is 240 V AC
to the dryer, perform the following test.
1. Unplug dryer or disconnect power.
2. Disconnect the wires from the thermal cut-
off.
3. Set the ohmmeter to the R X 1 scale.
4. Touch the ohmmeter test leads to the ther-
mal cutoff terminals. The meter should in-
dicate continuity (0 Ω). If the meter indi-
cates an open circuit (infinite), replace both
the thermal cutoff and the high-limit ther-
mostat. In addition, check for a failed
heater element, or a blocked, or improper
exhaust system.

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.
