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.
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 be plugged up or not be spinning properly, which reduces the air flow. Check to see if the blower wheel is securely fastened to the drive motor shaft.
If the dryer won't stop, the gas valve solenoid coils might be defective. Over time these coils will fail, causing the burner to run intermittently. If the dryer is not heating properly it may not stop. Replace the coils as a set.
The heating element warms the air before the air enters the dryer drum. If the dryer won't stop, it may be because the heating element isn't working - which greatly increases the drying time. Check the heating element for continuity.
The heating element assembly warms the air before the air enters the dryer drum. If the dryer won't stop, it may be because the heating element assembly isn't working - which greatly increases the drying time. Check the heating element for continuity.
Dryer sheets and fabric softener can leave a residue on the lint filter, reducing the air flow. If the dryer won't stop, check to be sure air can flow freely, clean the filter as needed.
Although not as common, if the dryer won't stop it may be because the moisture sensor is either defective or shorted.
If the dryer won't stop, check the high limit thermostat. If defective, the high limit thermostat can turn off the heat prematurely, lengthening the time it takes to dry a full load. This is not common.
The cycling thermostat regulates the temperature of the air in the dryer. If the dryer won't stop, it may be caused by a defective cycling thermostat turning off the heat too early. This is not common.
The thermistor senses the temperature of the air in the dryer and cycles the heat on and off. If the dryer won't stop, the thermistor may be defective. This is not common.
