Customer Questions and Answers for Igniter by Whirlpool

Bob, First place to check is the exhaust vent system, if the venting is restricted, the dryer won't cycle properly and you won't see a change in the temperature settings. Then test the cycling thermostat, remove the blue and purple wire from the termiankls and check for a "closed" circuit, then heat the thermostat with a match and check for an"open" circuit.Then check the thermostat heater circuit for approximately 2400 ohms resistance,with the wires off the components. If all's OK, You'll need to test or replace the temperature selector switch 33001640 .Here's some meter usage information should you need it [http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html].
