WARNING
Electrical Shock Hazard
Refer to page 4-14 for the procedure for ac-
cessing the thermal cutoff (TCO) and inlet
thermistor/high-limit thermostat.
1. Unplug dryer or disconnect power.
2. Disconnect the wires from the compo-
nent you are testing.
3. Set the ohmmeter to the R x 1 scale.
4. Thermal Cutoff and High-Limit Thermostat:
Touch the ohmmeter test lead to the com-
ponent terminals. The meter should indi-
cate continuity (0 Ω).
5. Set the ohmmeter to the R x 100K scale.
6. Inlet Thermistor: Use the following chart
to check the thermistor:
