Questions & Answers

For Whirlpool Dryer Temperature Selector Switch (Part Number: OEM18025128)

1 Answer

Larry, When you make a medium or low heat selection, 120 VAC is applied to the bias heater inside the thermostat WP3387134 through the temperature switch, the heater causes the internl contacts to cycle quicker causing less heat. When the regular or high temperature is selected the switch bypasses the bias heater, and the internal contacts cycle slower, causing a higher temperature.

Hello Trouble,

This sounds like you either have a bad drain pump, the drain pump is locked with debris, or the gear case has experienced a failure. It could have a broken part in the brake assembly that is causing the brake to remain locked. The drive block spanner nut could be loose allowing the tub to spin on the transmission shaft instead of being driven by the transmission shaft. As far as part numbers go, I need a model number to look parts up with.

David for Model Number LGR7646JQ1

Motor runs but no heat. There is no voltage to the ignitor. I tested the contacts on the timer and the correct ones are closed. I took an ohm reading of the heat switch (cycle) and it was open. According to the wiring diagram there should be a resistance in the line. Would this keep the heat off altogether. According to the diagram the ignitor gets its power through the red contact of the timer then through the t'stats and thermal fuse. Need help with this one. Thanks.

Hello James. Remove the hose from the back of the dryer and make sure the air duct inside the dryer, including the blower wheel are clean on the unit. If not, it will cause the problem you are having. Hope this helps.

Fred, The cycle switch is the least likely issue, at this point. A model number wouild've been a big help. Check and make sure the door switch and loading door are closing, and activating properly. Make sure you have to proper power supply to dryer, and the doesn't drop more than 10% when the dryer starts. We can be more precise and informaive, once e get a model number to work with. Thanks

Hi Chris. You first need to clear the entire vent system so the moisture gets removed from the clothes. Make sure the vent cap / hood is working correctly open and closed. The cycling thermostat is mounted on the blower hsg. It controls the cycling on / off of the heat. It should read 0-ohm, closed circuit. If not it is part #WP3387134. Thank You.

Hello John. Based on the information you provided, it sounds like the timer WP3976577 is bad and will need to be replaced. The timer should stop turning on the off contact, but if it is bad and sticks, it will continue to run. You will need to replace the timer. Hope this helps.

Packo, Once you get the sensor replaced, you'll most likely be fine, as long as you check and clear the dryer exhaust vent system. Your poor heat/ too long to dry description is a "classic" exhaust vent issue. Thanks and Good Luck
