Question about Whirlpool Dryers

1 Answer

This is the problem that I have with my Whirlpool LE9100XT electric dryer. When drying it would shut off then need restarted by pushing the start button again. This became more frequent in past few times I used it. I cleaned all the lint out of the hose and vent to no avail. Now it will not even start anymore. Is it possible that it is the start switch, a fuse or both? I don't have a parts break down for it.

Unplug the unit and take the back off. Down towards the bottom, nearthe exhaust connection, you will find a small, white thin plastic partwith 2 blue wires connected to it. Remove the wires, put them together,wrap with electrical tape, and then plug the dryer in and see if itruns then. 
That cutoff usually opens at about 196 degrees. The electronic controlin your dryer utilizes a thermistor instead of an operating thermostat.The control monitors the resistance in the thermistor and turns theheater on and off based on those readings. You might make sure thethermistor (right next to the open cutoff with 2 small wires on it) isclean on the sensing side by removing it and brushing it off.Basically, the exhaust temperature got too hot. This could be caused bya slightly restricted vent system, bad thermistor, or bad electroniccontrol. If the vent system is fully open all the way out, then I wouldprobably replace the thermistor, usually costing about 25.00.

You'll have to replace the cutoff, but if the thermistor is bad, thecutoff will blow again. It's not a very expensive part, but it's theonly way to effectively test the thermistor. You could use anelectronic temp meter to test exhaust temps to see what the lowest andhighest temps are at each setting on the control. If you do this, makesure to let the dryer cycle for 10-15 minutes before recording themin/max temps for each setting. High temp should not exceed 170 degreeswith an empty drum and disconnected exhaust system. If it does, I wouldreplace the thermistor. Really, either way you go, it's kind of acrapshoot. Welcome to the wonderful world of electronics andappliances....

if that doesnt solve ur problem... then its definitely ur thermal fuse... check if the dryer is getting 240 volts... if not ur thermal fuse is bad.... the fuse is around 10$...

If you find a blown thermal fuse, always clean, change, adjust the venting systemand vent hood first, then it is sometimes a good idea to replace the operating thermostat atthe same time. This is a picture of-some- modern thermalfuses.

thank you good luck if u feel i ve been of help to u... kindly rate my service... have a nice day

There is a loud squealing sound when I turn the dryer on. Whirlpool model GEW9250

Your dryer belt is loose, you may just have to open the dryer and reset the band, but most likely you will need to order a replacement set from whirlpool.

My dryer starts to dry but then shuts down after 5 minutes...why?

That is usually a sign of a bad motor. Can you immediately restart or do you have to wait a while?

It will run for 15 minutes then shut off. I restart it and it does the same. The lint trap is clean and when I open the door its not overheated.

it will start fine after it shuts off?
is there a delay? any humming before it starts? how many cycles do you have? does it work on one side but not the other? timed dry versus auto dry? sounds like your timer to me.
