What are the Common Causes of Dryer Shutdown?

A malfunctioning dryer that frequently shuts down can be attributed to various issues. Let’s explore some common causes that may lead to the premature shutdown of a dryer.


Overheating occurs when the internal temperature of the dryer rises beyond the normal operating range, triggering safety mechanisms that shut down the appliance. This can result from a variety of factors.

Clogged Lint Trap

One prevalent cause is a clogged lint trap, restricting airflow and causing the dryer to overheat. Regularly cleaning the lint trap is a simple yet effective preventive measure.

Worn or Defective Belt

A worn or defective belt can slip, causing friction and triggering the overheating mechanism. Inspecting and replacing the belt when necessary is crucial for smooth dryer operation.

Faulty Motor

The motor, often subjected to wear with age, can overheat and result in shutdowns. Regular maintenance and prompt replacement can mitigate this issue.

Blocked Dryer Vent

Proper ventilation is essential for preventing overheating. Ensure the dryer vent is free of obstructions, allowing hot air to escape efficiently.

Overloaded Dryer

Exceeding the dryer’s capacity with an overload of laundry can strain the system, leading to overheating and automatic shutdowns.

What are the Moisture Sensor Issues?

Moisture sensors in a dryer are responsible for gauging the moisture levels in clothes to determine when the drying cycle is complete. Malfunctions in these sensors can lead to premature shutdowns.

Faulty Moisture Sensor

A malfunctioning moisture sensor may misinterpret moisture levels, causing the dryer to shut off prematurely. Regular cleaning and, if needed, professional repair can address this issue.

Dirty or Clogged Sensor

A dirty or clogged sensor may fail to function correctly. Periodic cleaning with a soft cloth and warm water is advisable to maintain sensor accuracy.

What is the Door Switch Malfunction?

The door switch in a dryer is a safety feature that detects whether the dryer door is closed. Malfunctions in this switch can lead to shutdowns as the dryer may not operate with an open door.

Broken Door Switch

If the door switch is broken, the dryer may not detect a closed door, leading to shutdowns. Visual inspection and testing with a multimeter can identify issues with the door switch.

Damaged Wiring or Loose Connections

Wiring issues or loose connections affecting the door switch can also cause malfunctions. Professional assistance may be necessary for repair or replacement.

What are the Other Possible Causes?

Faulty Thermostat

Malfunctioning thermostats can disrupt the drying process. Regular checks and timely replacement can prevent such issues.

Gas Valve Issues

In gas dryers, problems with the gas dryer shut off valve can contribute to shutdowns. Professional inspection and repair are crucial for gas dryer users. You can also check the gas dryer troubleshooting guide.

Control Board Problems

Issues with the control board can manifest as erratic behavior. Resetting the circuit breaker or power switch may resolve some control board-related problems.
