Is your dryer timer keeps running long after the clothes should be dry? This can be frustrating, wasting your time and energy while leaving your laundry sitting in a hot drum.
You might wonder why your dryer won’t stop or how to fix it without calling a repair technician. The truth is, this common problem usually points to a few simple issues like a faulty timer, a stuck door switch, or a broken thermostat.
You’ll discover easy steps to diagnose why your dryer timer won’t quit and how to get it working properly again. Keep reading—your next load of laundry depends on it!
Common Causes
A dryer that keeps running after the cycle ends can waste energy and cause wear. Several parts inside the dryer may cause this problem. Understanding these common causes helps diagnose and fix the issue quickly.
Faulty Timer
The timer controls the drying cycle length. A mechanical timer can wear out or have stuck contacts. Electronic timers may have stuck relays. A faulty timer stops sending the signal to end the cycle. This causes the dryer to run endlessly.
Defective Thermostat
The thermostat controls the dryer’s heat and timing. It senses the temperature inside the drum. If the thermostat fails, it may not tell the dryer to stop heating. This can make the dryer run longer than needed, wasting energy.
Stuck Door Switch
The door switch tells the dryer if the door is open or closed. If it stays stuck in the closed position, the dryer thinks the door is shut. The dryer will keep running because it never senses the door is open.
Restricted Airflow
Clogged lint filters or blocked vents reduce airflow. This makes the dryer overheat. Overheating can confuse sensors and cause the dryer to run continuously. Cleaning vents and filters helps maintain proper airflow and dryer function.
Malfunctioning Moisture Sensor
Some dryers use moisture sensors to detect when clothes are dry. A faulty sensor may wrongly sense dampness. This causes the dryer to keep running to dry clothes that are already dry. Replacing or cleaning the sensor solves this issue.
Electronic Control Board Issues
The control board manages many dryer functions. If it malfunctions, it may fail to stop the cycle. Faulty circuits or damaged components on the board can cause the timer to run nonstop. Repairing or replacing the control board often fixes the problem.

Initial Checks
When your dryer timer keeps running, start with some simple checks. These initial steps help find common problems fast. They also prevent damage and keep you safe during repairs. Follow each step carefully before moving to complex fixes.
Unplug The Dryer
Always unplug the dryer before inspection. This stops power and lowers shock risk. Unplugging resets some electronic controls. Wait a few minutes before plugging it back in. This small step can sometimes fix timer issues.
Clean Lint Filter And Vent
A clogged lint filter or vent blocks airflow. Poor airflow makes the dryer overheat. Overheating can confuse sensors and stop the timer from ending. Remove lint from the filter after every load. Also, check and clean the vent pipe regularly.
Inspect Door Switch
The door switch signals if the door is open or closed. A stuck or broken switch tricks the dryer into running nonstop. Press the door switch by hand to test if it clicks. Replace the switch if it feels loose or does not click.
Testing Components
Testing the key components of your dryer helps find why the timer keeps running. Focus on the timer, thermostat, and electrical parts. Use simple tools to check if parts work correctly. This process saves time and avoids unnecessary repairs.
Use A Multimeter
A multimeter measures electrical current, voltage, and resistance. It helps check if the dryer parts get power and work properly. Set the multimeter to the correct setting before testing. Always unplug the dryer to avoid shocks. Use the multimeter probes on the timer or thermostat terminals. Look for clear readings that show the part is functional.
Check Timer Continuity
Continuity means the electrical path is complete. Test the timer by placing the multimeter probes on its contacts. A reading of zero or near zero means the timer works. No reading or infinite resistance shows a broken timer. Replace the timer if the continuity test fails. This step ensures the timer can stop the dryer cycle as it should.
Test Thermostat Function
The thermostat controls the dryer’s heat and run time. Test it with a multimeter for continuity. When cold, the thermostat should show continuity. If it does not, the thermostat is faulty. A bad thermostat may cause the dryer to run endlessly. Replace any thermostat that fails the test to fix the problem.

Electronic Model Troubleshooting
Electronic dryers rely on advanced control systems to manage their cycles. Troubleshooting these models requires checking key electronic components. These parts control timing, motor operation, and safety features.
Understanding common electronic issues helps fix a dryer that keeps running. Focus on the control board and motor behavior for accurate diagnosis.
Identify Control Board Problems
The control board acts as the dryer’s brain. It sends signals to start and stop the timer and motor. A faulty board may cause the timer to run endlessly. Look for burnt marks, loose wires, or damaged parts on the board.
Use a multimeter to test the board’s relays and connections. A stuck relay can keep the timer active. Replacing the control board often solves persistent running issues.
Motor Running With Door Closed
The dryer motor should stop when the door opens. If it runs with the door closed, the door switch may be faulty. This switch tells the motor when the door is open or shut.
Test the door switch with a multimeter for continuity. If it does not open the circuit when the door opens, the motor keeps running. Replace the door switch to restore proper operation.
Replacement Tips
Replacing parts in a dryer with a timer that keeps running requires care. Choosing the right components ensures the repair lasts. Knowing when to replace the timer or thermostat avoids extra problems. Sometimes, replacing the door switch fixes the issue quickly. These tips help you restore your dryer’s proper function.
Choosing The Right Parts
Select parts that match your dryer’s model number exactly. Use OEM (original equipment manufacturer) parts for best results. Avoid cheap, generic parts that may fail quickly. Check the part number on your old component before buying. Reliable parts improve safety and performance.
When To Replace Timer Or Thermostat
Replace the timer if it runs continuously without stopping. A faulty timer often causes the dryer to keep running. Change the thermostat if the dryer overheats or won’t shut off properly. Test these parts with a multimeter to confirm they are defective. Replacing the right part saves time and money.
Replacing Door Switch
The door switch signals if the door is open or closed. A stuck switch can make the dryer run endlessly. Test the switch by opening and closing the door while the dryer runs. Replace the switch if it does not respond correctly. This simple fix stops the timer from running nonstop.

Preventive Maintenance
Preventive maintenance helps keep your dryer running smoothly and avoids timer issues. Regular care reduces the risk of the timer running endlessly. Small tasks performed often can extend the dryer’s life and improve safety.
Regular Cleaning
Clean the lint filter after every use. This prevents lint buildup that blocks airflow. Also, vacuum the vent and ductwork yearly. Clear vents help the dryer cool properly. A clean dryer runs more efficiently and avoids overheating problems.
Avoiding Overheating
Do not overload the dryer with clothes. Overloading causes the machine to work too hard. It can lead to excessive heat and damage the timer. Use the correct drying cycle for fabric types. Proper airflow keeps the timer functioning correctly.
Routine Component Checks
Check the door switch to ensure it clicks when closed. A stuck switch may cause the timer to keep running. Inspect the thermostat and moisture sensor for damage or dirt. Replace worn parts to maintain correct timer operation. Regular checks prevent long-term failures and improve dryer safety.
