I have a Maytag mod. MEDC400VW0 elect. dryer about 3 years old. When the dryer reaches the end of its cycle the timer continues to move,the tumbler stops , but the heating element stays on. The dryer gets very hot since the tumbler is not moving. Do I need a new timer?
That sounds really strange and really dangerous.
Most dryers have a start switch that turns the power off (to the heating element) when the motor stops. Unless you have a short in your wiring, you have a bad motor. (The start switch is part of the motor).
Don’t let this dryer run like this. If it doesn’t blow its thermal fuses it will be a wonder.

Your heating element may be grounded.
Unplug the unit and both wires to the heating element.
Check the heating element resistance should be about 8 to 12 ohms.
Then check from each heater connector to the chassis (frame) both should be infinite ohms. Be sure to find an unpainted spot or go to the terminal strip.
If not infinite ohms replace the heating element often you can see where is is touching the case.
