Top 8 Reasons Your Clothes Dryer Won’t Stop Running

Share with friends


Has it lately seemed that your dryer takes an eternity to finish a load of laundry?

It’s typical for one load to take longer than another to dry. Variables such as size of the load, density of the fabric, and the dryer settings you use, can all impact the amount of time a load takes to finish drying.

But if you’ve noticed lately that your dryer seems to be taking far longer than usual to finish, you might have a mechanical problem on your hands. When a repairman examines your dryer, he’s likely to find that your problem stems from one of these common causes:

#1: Air Flow Restriction

To work properly, your dryer must constantly cycle moist air out, and fresh air in. But if the intake vent becomes restricted, the dryer might not be able to pull in enough fresh air to work efficiently.

The problem could lie anywhere within the intake system. It could be a clog within the dryer’s internal ducting, within the external vent, or anywhere in the ductwork in between.

#2: Bad Blower Wheel

The blower wheel is responsible for cycling fresh air into the dryer, and moist air out. If this wheel becomes clogged with lint or debris, airflow will be reduced, and drying time increased.

Sometimes blower wheels can become disengaged from the drive motor shaft. The motor runs, but the blower wheel doesn’t turn at full speed.

#3: Defective Gas Valve Solenoid

On gas dryers, the solenoid that controls the operation of the burner may occasionally fail. When this happens the burners may operate intermittently, extending drying time.

#4: Heating Element Problems

On electric dryers, the heating element is responsible for heating air as it enters the dryer’s drum. Extended drying time may indicate that the heating element isn’t working properly, and might need to be replaced.

#5: Lint Filter Restriction

A clogged lint filter can extend the time it takes for your dryer to complete a load. Check the filter carefully to be sure that it’s clean. Even if there’s no lint present, a residue from fabric softener and dryer sheets can build up over time, restricting airflow somewhat even when lint isn’t present.

#6: Failed Moisture Sensor

Some dryers use a moisture sensor to determine when a load is sufficiently dry. If this sensor fails, the dryer may continue running long after the load of laundry is completely dry.

#7: Faulty Thermostat

A thermostat (or thermistor) regulates the air temperature in the dryer drum. A failing thermostat might be turning the heat off in your dryer prematurely.

#8: Timer Defect

It could be that your dryer has developed a problem with the timer. Sometimes timer motors can go bad, causing the timer to remain stuck at a certain setting instead of progressing normally through its cycles.

And sometimes the contacts within a timer can become stuck. An indication that this has happened is when the timer knob shows that the timer has progressed normally to the “off” position, but the dryer continues to run.
