The dyer does not fully dry the clothes at the end of the cycle.
The first thing to check is the dryer venting from the blower wheel to the outside of the home. If there is a restriction it will cause longer drying times.
Dryer does not buzz when cycle is done.
Answer Dave, Have you checked the buzzer WE4M318 for a "closed" circuit, with a multi meter, or applied 120 VAC across the two terminals to see if it buzzes ? Ot the timer contacts for the buzzer circuit at the timer(t to s) ? The buzzer operation is accomplished through the neutral circuit at the motor switch as the motor is "ramping down" when power is turned off through the timer motor, when the timer reaces the off position. So you may have a broken or loose wire between the motor and buzzer, or the motor switch/motor is failing. Thanks and Good Luck
