Air Flow Problem The most common problem when a dryer is slow is when the vent is clogged. If the dryer is slow, check the vent from the back of the dryer to the outside of the house. If that is clogged, clear it completely and test the dryer. If the dryer is slow after the vent is cleaned, clean the internal ductwork of the dryer. This will require some disassembly.
Blower Wheel

Item # 686172
The blower wheel draws air through the dryer and pushes the air out the vent. If the dryer won't stop, the blower wheel may not be spinning properly, which reduces the air flow. Check to see if the blower wheel is securely fastened to the drive motor shaft.

The blower motor is not working properly. Turn the stove off and remove the front cover. Remove the lower baffle in the front. Remove the black hose that is about 1 1/2" in dia. If it breaks don't be surprised. Stick a pencil in the hole and spin the fan. Keep trying until it spins freely. If it spins freely from the start the motor is burned. Put the black hose back on and try to start. IF the hose broke you will need a new one. For now put some electrical tape around the break to get you going.

Keep us posted.
