Here are your parts Parts for MED97000SB0 - AppliancePartsPros.comSee the attachment for the tech sheet. Sounds like a problem with the moisture sensor. The tech sheet has some info on how to test it. The way that the moisture sensor works is that a low voltage is applied across the metal strips. When there is moisture between them, this allows a small current to flow. The board senses this current and holds the timer off. When the clothes are dry, there is no moisture between the strips therefore no current and the timer advances to off. Your problem sounds like the unit is not sensing the moisture between the strips so it thinks the clothes are dry re: always infinite resistance. This could be as simple as a wire has come off the sensor strips. Unplug the unit. Set your meter to a high resistance scale. Measure P2-1 to P2-2 at the control board. Should be either an infinite resistance or ea very high resistance. Now wet your thumb and place it on the sensor bars. The resistance should decrease. If it does there is a problem with the control board. If it does not then there is an open connection in the sensor bar circuit.

Hello, I have a Maytag MED9700SB0 Electric dryer that I got used without any knowledge about its history. Its pretty clean inside and out, so seemingly well taken care of.
Anyway, when I run the dryer on any of the automatic settings the "sensing" light comes on and the dryer will run from a few to maybe 10 minutes and then shut off with the "cycle complete" light on. I have yet to see either the "wet" or "damp" lights on, it just skips them, says cycle complete and leaves me with warm wet clothes.
One time with wet towels it was running for nearly 10 minutes and "sensing." So i opened the door, took a wet towel and rubbed it against the sensor bars, closed the door, started the dryer again, and within about 10 seconds the dryer turned off with the "cycle complete" light on.
If I run it on timed dry it completes the cycle without issue.
I have tried cleaning the sensor bars with rubbing alcohol, an eraser, an emery board, and some high-grit sandpaper. The last seemed to extend how long it runs before completing the cycle, but it still only runs for a short time.
Further research says that if dryer doesn't detect moisture by 10 minutes in auto mode that it will shut down. So do I need to replace just the sensor bars, or is there something more that they connect to that is not working properly?
having done a little research, other's experiences seem to point to the temperature thermistor or the moisture sensor bars themselves.
any idea?
thanks for your help
