When a dryer stops mid-cycle, it interrupts more than just laundry. It can throw off your entire day and leave clothes damp when you need them dry. Understanding why this happens helps prevent bigger issues later. Most causes come down to heat, sensors, or airflow. Once you know what to look for, you can fix small problems early and avoid unnecessary repairs.
Overheating from Blocked Airflow
A dryer needs constant airflow to stay cool while operating. If that airflow is restricted, the internal temperature rises too quickly, and the machine shuts off to protect itself. The most common reason for overheating is a clogged lint screen or vent. Even a thin layer of lint can block air movement, so cleaning it after every load makes a difference.
The vent line behind the dryer can also fill with lint or even small animal nests, especially if the duct leads outside. When the hot air has nowhere to go, sensors inside the dryer trigger a safety shutdown. Disconnecting the vent and running the dryer for a minute on air-dry mode can help you test if the airflow is blocked. If it runs fine that way, the issue likely sits in the vent or duct.
Long vent runs, crushed hoses, or vents that go through cold areas of the house can also cause moisture to condense and create blockages. Keeping the vent path short and smooth improves drying efficiency and prevents mid-cycle shutdowns.
Failing or Overheating Motor
When a motor works too hard, it can overheat and stop running to protect itself. Once it cools down, it may restart and run for a while before shutting off again. That pattern is a strong clue that the motor needs attention. Dust, lint, or restricted ventilation inside the motor housing often trigger these temperature spikes.
If you notice a burning smell or unusual noise before the dryer shuts off, stop using it until it is checked. A motor that overheats repeatedly can fail permanently or even damage nearby components. Professional servicing can test the motor’s windings and bearings to confirm whether cleaning or replacement is needed.
Sometimes, a weak start capacitor or worn bearings make the motor strain even under normal loads. When that happens, the dryer may stop mid-cycle only when full but run fine with smaller loads. Testing with lighter loads helps narrow down the issue before calling for help.
Faulty Door Switch or Loose Latch
A dryer door that does not stay securely closed can interrupt power flow mid-cycle. Even a slightly loose latch can trigger a stop signal. Over time, the metal catch and plastic door switch wear out from repeated use. If the dryer stops randomly and starts again when you press on the door, the latch or switch is probably the culprit.
Inspect the latch area for debris, lint buildup, or worn plastic. Cleaning it gently and checking the alignment often restores a good seal. If that doesn’t help, the switch itself may need replacement. Door switches are inexpensive parts, but replacing them prevents electrical interruptions that could affect other components.
Defective Moisture Sensor
Modern dryers use moisture sensors to determine when clothes are dry. These sensors detect the level of humidity in the drum and adjust cycle time accordingly. If a sensor becomes coated with fabric softener residue or lint, it can send false readings. The dryer may think the clothes are already dry and stop early, even if they are still damp.
Wiping the sensor with a soft cloth and a small amount of rubbing alcohol can restore its accuracy. The sensor bars are usually located inside the drum, below the lint screen area. A quick cleaning every few months keeps them working properly and prevents premature cycle stops.
If cleaning doesn’t help, the sensor might have failed and will need replacement. Fortunately, this is a simple and low-cost repair compared to control board issues.
Thermostat or Thermal Fuse Problems
The thermostat regulates temperature, while the thermal fuse protects against overheating. If either part fails, the dryer may shut off before completing a cycle. A blown thermal fuse cuts power completely until replaced. A faulty thermostat, on the other hand, can shut down the heating element early or cause erratic cycling.
When a dryer suddenly stops mid-cycle and will not restart until it cools down, it often points to a thermostat issue. Testing both parts with a multimeter helps confirm the problem. Because these components directly affect safety, they should be replaced only with compatible parts designed for your specific model.
A professional familiar with appliance repair services in Surrey can quickly identify whether a blown fuse or defective thermostat caused the interruption. Proper testing prevents replacing the wrong part and keeps your dryer running efficiently.
Control Board Malfunctions
The control board functions like the dryer’s brain. It directs power to the right components based on sensor feedback. When a board develops a weak relay or faulty connection, it can misread signals and shut down mid-cycle for no clear reason. Power surges, moisture, and general wear contribute to this issue.
If your dryer’s display flickers, resets itself, or shuts off at random intervals, the board may be failing. Unfortunately, these problems often look similar to simpler issues, like a bad sensor or thermostat. Running diagnostic tests or observing error codes helps confirm the cause.
While control board replacements can be expensive, they often extend the life of the dryer by restoring consistent operation. It’s usually worth testing all simpler possibilities before replacing this part.
Clogged or Restricted Blower Wheel
The blower wheel moves hot air through the drum. If it becomes clogged with lint or small debris, airflow drops sharply, causing overheating and shutdowns. You might hear rattling or scraping sounds just before the dryer turns off.
Unplugging the dryer and inspecting the blower housing for lint clumps can help confirm this issue. Regular cleaning of the lint screen and vent line reduces the chances of blower blockages. If the wheel is cracked or wobbly, replacement is the best option.
Poor Power Supply or Loose Connection
A dryer that loses power mid-cycle can point to an issue outside the machine. Loose plugs, tripped breakers, or faulty outlets cause sudden shutdowns. Electric dryers require 240 volts, so if one leg of the circuit fails, the drum might spin but the heat will cut out.
Checking the plug connection and ensuring the cord is not bent or frayed helps rule out simple problems. If your lights flicker or the breaker trips often, the problem might be with the electrical circuit. An electrician can verify voltage and tighten connections where needed.
Software and Sensor Resets
Some newer dryers include software-driven controls that can glitch occasionally. Resetting the machine can clear temporary faults. Unplug it for five minutes, then plug it back in. This step resets sensors and control logic, which sometimes restores normal function.
If the dryer works fine for a while after resetting but fails again later, the underlying issue is likely with a sensor or motor component rather than software alone.
Maintenance Habits That Prevent Mid-Cycle Shutdowns
Simple routines extend dryer life and prevent shutdowns. Cleaning the lint screen after every load keeps airflow steady. Wiping the moisture sensor once a month maintains accurate readings. Every six months, disconnect the vent and clear lint from the duct and exterior flap.
Avoid overloading the drum, which strains the motor and traps heat inside. Make sure the dryer sits on a level surface so it can rotate smoothly. Check the plug for heat or discoloration that might suggest poor contact.
Scheduling a yearly inspection ensures all safety parts and sensors function properly. Regular checks prevent small issues from turning into expensive breakdowns.
If your dryer keeps stopping mid-cycle despite these steps, professional diagnostics may be needed. A trained technician can test internal components with specialized tools and restore normal operation.

FAQ
Why does my dryer stop after ten minutes?
A blocked vent or overheating motor often causes short run times. Clean the lint screen and vent, then try a smaller load to see if it completes.
Can overloading cause my dryer to shut off?
Yes. When the drum is too full, air cannot circulate properly, which raises the temperature and triggers safety sensors.
Why does my dryer only stop on certain settings?
That usually indicates a faulty timer or control board that fails under specific conditions. Testing other cycles helps confirm which setting is affected.
Is it safe to keep restarting my dryer when it stops mid-cycle?
No. Repeated restarts without finding the cause can overheat components and worsen the damage. Identify and fix the problem before running another load.
What should I do if cleaning the vent doesn’t fix the issue?
If airflow is good and the dryer still stops early, the problem could be electrical or mechanical. Contact a technician to test the motor, thermostat, or control board.
