Timer dial not working correctly
Unclip the control panel and roll back, unscrew old timer switch and install new one, same with the push-to-start button/switch
The dryer took at least 3 rounds to dry light clothes and 4-5 for towels.
This was my second time making repairs. The only difference this time I replaced all parts from top to bottom. When I pulled the heating element out only one coil was working the others had burned out. It was easy to do and the videos on the site are very helpful and informative. I followed the steps and if I thought I missed a step I replayed it again. I am a woman and found it very easy and not at all intimidating at all. I am going to hopefully have it for another 10 yrs. You guys keep up the good work.
Moved top control panel and pulled cabnet back changing switch,then reassembled,very easy,don’t forget to un plug

start switch replace
i could not perform the repair because despite using the proper id numbers, i received the wrong parts from kenmore three times in a row. now i am trying to return the wrong parts which cost me 120.00 for the start switch, and the knob for the switch, so far. the switch was 40.00 the simple plastic button was (wrong) 40.00, and the wrong unidentifiable part, suposedly correct one, which also was 40.00. this, with the original 40.00 wrong switch amounted to the 120.00 that i am still trying to have returned. otherwise, the fix should be quick and simple, o yeah, its been three months.. you tell me if i am satisfied....

The Dryer wouldn't start after pressing the Start Button.
I found a video tutorial that explained the three things that are usually the problem when a dryer stops working. This showed how simple the task is. I used a multimeter to check the switch, to make certain that this was the part that needed replacement. This was part of the tutorial, as well. I ordered from PartSelect because it was recommended to me by an application that I use to find places where items are less expensive. The correct part arrived in a few days and it worked fine. I'm not a handyman by any means, but the tutorial showed exactly what needed to be done. It appeared simple and it was.

dryer stop working
1st- installed the push to start switch-was not the problem 2nd installed the dryer thermal fuse and was not the problem 3rd installed the dryer door switch and the dryer started right lup
Actually this site also has a video on how to do this repair, which was awesome. Mine was slightly different because the top where the controls were didn't raise up like on the video.I unplugged the dryer. I had to take the nuts off the back metal sections to expose the parts. I popped the Push-To-Start button out, removed the fuse and put the new parts on. Put the metal sections back on and plugged it in. WA LA it worked!! I probably didn't need the push button part but figured I might as well use it since I bought it. I do believe it was the Thermal fuse that was bad. Saved me probably over $100.00 by doing it myself.
After unplugging and removing the back cover from the dryer, locate the push button switch. Slide putty knife around outer cover to unhook catch. Replace with new push button switch. My dryer is still not working, but this was a simple replacement.

The dryer will start when start button is pushed but will not stay running. I have replaced the start switch but still won't stay running. Heating is fine, cleaned out lint from machine when I replaced start switch. What is the likely culprit of this problem? Thanks!!
For model number LER4634PT1
Hi Theresa, Thank you for the question. The first thing to check is the Door Catch Kit,PartSelect Number PS334230 to make sure it is staying latched and secure. If this part is lose and the door is not fully closed it will turn the dryer off.It is also a good idea to check the Door Switch Assembly,PartSelect Number: PS11742178.If the door switch and catch are good you can test the Internal-Bias Thermostat, PartSelect Number PS11741405.A cycling thermostat is in tune with the temperature of your dryer and regulates it in order to maintain a certain temperature. This thermostat reaches a temperature of 155 degrees, turns off, and then turns on again once it has dropped by 25 degrees. If your dryer is not staying on or turning off to soon this could be the issue.Hope this helps!
Issue: The only way the dryer will run is if you hold in the push to start button.You can tape it closed and it keeps running. Would this be a switch replacement issue of something else?
For model number 110.64982300
Hi Dominick, Thank you for the question This issue could be a defective motor. The motor shoudl stay on once the switch is released.You can check the start switch to see if there is continuity without pushing the button. If there is then this would be a faulty start switch. If the start switch is good then this will be a faulty motor. Hope this helps!

I ordered the push start switch/button (part#3977456) for my Whirlpool electric dryer. What i received was wp3977456. The white "frame" around the new part isn't like the original. So, how is it going to work, or do i need to find one like the original?
For model number LEB6000KQ1
Hi Rachel,
Thank you for the great question! Even though this part is not the same as your original, it should actually still install the exact same way. I hope this helps!

Dryer does not start when pushing start button. If you hold start button in the dryer will run. Does that switch have some type of contact to hold it closed or is there a relay somewhere? What part do i need?
For model number GEW9878LW0
Hi Jerry,
Thank you for your question. If pressing the push-to-start switch will not will not start the dryer without you holding it down, there may be a connection issue with the wiring attached to it that you will have to check. You will need to make certain it is attached firmly and not loose where it is mounted. I hope this helps. Thank you and have a great day!

My dryer runs fine, but when i open the door(while it is running) it will not stop. What part should i be replacing?
Hi Kathy, thank you for your question. You should always pause or cancel the cycle before opening the door. It is likely that you will have to replace your door switch. I hope that helps. Good luck with your repair.

I have a Amana ngd5100tq1, won't start only buzzes when pushing the start button. Is this the part that i need?
For model number NGD5100TQ1
Hello Jeremy, thank you for your question. The issue could be the push to start switch, door switch, or capacitor on the motor. We would recommend testing the switches to confirm if they are faulty or not before ordering. I hope this helps!
