Hi Gene,
I too am having the EXACT same problem that John is seeing. About a month ago, my Maytag MDG8400AWW dryer (serial number 228964411CR) timer stopped moving.
I did a little research and ordered a replacement Timer (33002855) from APP. That did not fix the problem.
I then ordered a replacement the Sensor Assembly (33002734). I examined it before I replaced it and visually it was IDENTICAL to the one that is currently in there, including the PCB assembly number on the circuit board.
When I put the new board in, it worked for about 10 minutes and then all of a sudden I heard a pop and the sensor light was out and there was a burnt smell. I turned it off and unplugged the dryer to find that the Q2 component on the board had fried, all the way to where the Blue (34) and Brown (15) are on the connector.
I am currently stumped. I am not sure if I just got a defective Sensor Assembly.
Just wondering if you could give me any advice?
Thanks!
-Rob

I dd the same exact fix as you did with the exact same result. After that hapened I felt soooo frustrated and technically incapable of trouble shooting this appliance that I went to my appliance parts store near by and hung out to talk to an appliance repairman coming in for parts.
A really nice repairman said that that dryer has always been difficult to diagnois and he said to foget trying to fix it and get something different than that model. I took his advice and have been so happy.
I am hoping that you will finally figure out what causes the circut board to short out and how much it actually costs you to resolve the problem.

So far, I have spent about $70 on a timer and $25 on the intellisensor board. I might try to get a new board and put it in with the new timer...
Still cheaper than a service call...

Just to make sure you understand that my fix was exactly what you are proposing. The new circuit board blew up with a neew timer. Do you have your old circuit board? When I looked at my old board it was also blown up. So on my dryer I went through two timers (thinking the first timer was the problem) and one circuit board.
Something other than the timer is causing the circuit board to blow up.
