4.Electric Dryers Only:
a)Connect the ohmmeter test probes to the red wires at the thermal cutoff and the heater.
•If the resistance is approximately 10 Ω, proceed to step c.
•If an open circuit is detected, go to step b.
b)Visually check the wire connections to the thermal cutoff, the

c)If no open circuit is detected, measure the resistance between
•If 6 to 7 kΩ are measured, replace the electronic control board.
•If the resistance is less than 1 kΩ, replace the thermistor.
Heat will not shut off:
1.Unplug dryer or disconnect power.
2.Use an ohmmeter, and touch the test leads to electronic control board points
•If 6 to 7 kΩ are measured, replace the electronic control board.
•If the resistance is much greater than 7 kΩ, replace the thermistor.
TEST #3a: THERMISTOR TEST
The electronic control board monitors the ex- haust temperature using the thermistor, and cycles the heater relay on and off to maintain the desired temperature. Begin with an empty dryer and a clean lint screen.
1.Plug in dryer or reconnect power.
2.Set the dryer for the following configura- tion:
•Door firmly closed.
•Press CONTROL ON.
•Press CYCLE END SIGNAL (Loud).
•Press HOLD TO START.
3.If after 60 seconds, E1 or E2 flashes in the display and the dryer shuts off, the ther- mistor or wire harness is either shorted or open.
•Unplug dryer or disconnect power.
•Check the wire connections at the elec- tronic control board and thermistor.
•If the wire connections are good, re- move the two wires from the thermistor, and replace the thermistor.
•Plug in dryer or reconnect power.
