Kenmore HE5t Dryer Does Not Heat


Thanks for providing all of those details. Your final detail seems to indicate that the igniter is not glowing at all. The fact that the gas valve coils seem to be heating up implies that the gas burner assembly is likely getting voltage. The first image below shows the theory of operation for the gas valve assembly. The resistance of the gas valve coils will normally increase when they are heated up. Assuming that the gas valve assembly is getting voltage, you could have a bad flame sensor that is preventing the igniter from glowing. The voltage path through the igniter is traced in red on the wiring diagram in the second image. If that flame sensor is "open", then the igniter will not glow. You could unplug the dryer and bypass that component by taping the wires that go to the flame sensor together with electrical tape. (You could also check it for continuity using a volt/ohm meter to test it.) Carefully check to see if the igniter glows with the flame sensor bypassed. (If you checked it with a volt/ohm meter and it is okay, then this component will not prevent the igniter from glowing.) If the igniter glows with the flame sensor bypassed then replacing that component may fix this problem. NOTE: The burner will not actually ignite with the flame sensor bypassed. The flame sensor has to "open" when the correct ignition temperature is sensed so that current will flow through the gas valve coils and the valves will open to light the burner.

NOTE: Be sure that you disconnect electrical power after performing the above test. Power should be disconnected from the dryer when accessing internal components. If power is needed for a brief test, it should be disconnected immediately following the test. Do not make contact with live wires or contacts inside the dryer when it is connected to electrical power.

If the flame sensor is okay and is not preventing your igniter from glowing, I recommend that you check the continuity through the high limit thermostat. The tech sheet does not mention that component but it could prevent the igniter from glowing. A wiring failure could also cause this problem.

I hope that these tips help. If you need more assistance, reply with additional details.
