FOR SERVICE TECHNICIAN ONLY - DO NOT REMOVE OR DESTROY
Replace the heater if it is electrically open.
Replace both the thermal cut-off and high limit
thermostat (inlet thermistor/high limit thermostat
assembly on Amana models) if either the thermal
cut-off or the high limit thermostat is electrically
open.

(P4 on Amana models) connector, then measure
the resistance between P14-3 (P4-3 on Amana
models) (red wire) and P14-6 (P4-6 on Amana
models) (red wire) at the connector. See figure 16,

GAS DRYER:
1. Unplug dryer or disconnect power.
2. Remove the toe panel to access the thermal
components.
3. Perform TEST #4b, page 17. If the thermal
fuse is OK, go to step 4.
4. Perform TEST #4c, page 17. If the thermal
cut-off is OK, go to step 5.
5. Locate the high limit thermostat. See figure

connecting the meter probes on the red wire
and black wire terminals.
