The timer won't advance beyond the cool down point in either timed mode or electronic dry sensor mode. I've cleaned thesensor insode the drum and checked the connection to the sensor but that has made no impact on the result. The questions I have is do I buy a new control board ($147) or a new sensor ($8)? It seesm the sensor is a pretty simple device and is not prone to malfunctioning. Also, no softener or anti-static sheets are used so no build up on the sensor. Any advice on assuming the problem is the board? Thanks.

You mentioned that the flame sensor was a simple device and not prone to malfunctioning. That has not been my experience. I replaced the sensor in my KitchenAid dryer several years ago, and now the burner is not igniting again. It might not be the sensor, but I'm going to try it first, because it is a cheap, easily accessible part. The symptoms are the same as before, the igniter is glowing as usual, but after about 10 seconds cuts off without gas being supplied to the burner.

One very distinct thing I noticed with the first sensor failure, and noticed again this time: a very strong, acrid, "burnt electrical wiring" smell, about the time the dryer stopped heating up.

I would expect that the flame sensor's position almost on top of the combustion chamber, or "tube," exposes it to a lot of heat, this leads me to think that it would be susceptible to failure before other parts necessarily would.

I know this reply is too late for the original poster, but hope it might be helpful to anyone else surfing into this forum, like I did. Good luck!

OOPS... I just realized we're talking about two different sensors! You're referring to the "dryness detection" sensor, and I misread and thought you were talking about the flame sensor. My bad, I apologize, but maybe the info will be helpful to someone else anyway...
