Follow the troubleshooting listed below, you will need an ohmmeter and a basic understanding of how to use it.

 1. Unplug the dryer or kill power to it at the breaker.

 2. Remove the toe panel to access the thermal components.

 3. Using an ohmmeter measure the resistance from the red wire terminal at the thermal cut-off to the red wire terminal at the heater. ➔ If the resistance is about 10 Ω, go to step 5.

➔ If an open circuit is detected, go to step 4.

4. Visually check the wire connections to the thermal cut-off, high limit thermostat, and heater. If connections look good, check for continuity across each of these components.

➔ Replace the heater if it is electrically open.

➔ Replace both the thermal cut-off and inlet thermistor/high limit thermostat assembly if either the thermal cut-off or the high limit thermostat is electrically open.

5. If no open circuit is detected, remove the P4 connector, then measure the resistance between P4-3 (red wire) and P4-6 (red wire) at the connector.

➔ If 5–15 kΩ are measured, replace the machine control electronics.

➔ If the resistance is less than 1 kΩ, replace the outlet thermistor.
