How to Troubleshoot & Replace Whirlpool AP6007999 / WP33002803 Timer

Unplug dryer from wall opened up control panel unplugged timer from harness removed outer cap from control knob pulled off outer ring slid timer to left to disengage reverse order to install new plug dryer back in wall 

Took The Control Panel Cover Off. Start switch was visible then. I unplugged the wire harness and slid the switch to the left to remove. 

First of all, I checked to make sure everything else was good on the Maytag Dryer. And per chance I cycled the timer a few times and got it to work. But as soon as I shut it off it never ran again. That was until I found a timer at a discounted (non OEM) site. And when I put it in it ran but the timer advance was not working, And when you opened the door and it would not shut off. So I did some research and the model # will get you the part, but the serial # will get you the right part. So I called up Appliance Parts Pro. And they found the right part for my "Series" of Maytag dryer So I ordered it that morning and I received it the next Day! I put it in. (it was Quite simple to install, less than 5 minutes.) And started right up and everything works as it should. Thank-You, David 

I took out 2 screws, and replace the timer in about 2 min. 

Replaced timer- fixed it... Took longer to find the right size Torq screwdriver bit than the actual replacement. 

First called a "repairman" who looked at everything but the timer on the dryer. He informed me that a new timer for my dryer was not available because they were discontinued. Said I would have to replace the dryer. Not satisfied, and $75 service fee poorer, I went online to Appliance PartsPros.com and found the exact timer I needed. Received 2 days after ordering. Watched the APP.com video on how to replace the timer. Followed your instructions and replaced timer in under 15 minutes. Timer runs just like new! Second time I have ordered parts from APP and they are great. You guys have the parts and ship very quickly. I will recommend you to anyone. 

The first switch was delivered in an opened package,the second was delivered ok and installed. 

Replaced timer. Lots of confusion on which timer is needed for this dryer (Maytag MDE6400AYW) so do your research. First timer was not the correct part, returned it. I was told I would need to change out the wiring harness for the entire dryer to make the second timer work. Decided to try just installing the timer which worked. So no need to change out the wiring harness. I will not the super fast shipping of parts which was very nice. 

Replaced the timer. I used the step-by-step on-line video from ApplicancePartsPros.com. It was very helpful and made the repair easy! 

Replace the timer control.
