Dryer is shutting down too soon
I’m working on a Maytag MEDC300xw1 purchased in 2013. Dryer is shutting off just a few seconds after being turned on and will not run at all on some settings. Owner says it started cutting off after about 5 minutes into a cycle, but if she played with the knob she could get it to come back on for a few minutes. Said sometimes it comes back on by itself. She stated in the beginning the dryer would run the full cycle but the clothes wouldn’t be dry. It’s has slowly deteriorated to the point that it will only stay on for a few seconds. I tested the high limit thermostat, the thermal cut off fuse, and the cycling thermostat with a multimeter and all were closed. Heating element works. No clogs in vent hose or on the outside of the house. Lint filter was clean and the chute was not clogged. Blower turned easily. No obstructions. Belt was in good working order and tumbled. Door latch worked fine and door sealed well.
No humming or other weird noises from the motor while dryer is running and there was no click a few minutes after dryer stopped to indicate an over heating motor that cooled down.
I am at a complete loss as to what is wrong with this dryer and why it keeps shutting off so quickly. Help!!!
