Common Causes
Basic troubleshooting helps identify simple problems causing the dryer to run nonstop. It saves time and money before calling a technician. Follow these easy steps to check common issues.
Cleaning Lint Filter And Vent
Start by removing the lint filter. Clean out all lint and debris. A clogged filter blocks airflow, causing the dryer to overheat and malfunction.
Next, inspect the vent hose. Clear any blockages or lint buildup inside. Proper airflow helps the dryer detect moisture and finish cycles correctly.
Wiping Moisture Sensors
Moisture sensors inside the drum tell the dryer when clothes are dry. Dirt or residue on sensors can give false readings.
Use a soft cloth with mild soap and water. Gently wipe the sensors clean. Dry them well before running the dryer again.
Inspecting The Door Switch
The door switch tells the dryer if the door is open or closed. A faulty switch may cause the dryer to run continuously.
Press the door switch manually. Listen for a clicking sound. No click may mean the switch is broken and needs replacement.
Check the switch wiring for loose or damaged connections. Secure or replace wires if needed.

Safety Precautions
Advanced repairs fix complex issues causing the dryer to run nonstop. These repairs involve checking key components beyond simple fixes. Proper diagnosis saves time and prevents further damage. Skilled handling ensures the dryer works safely and efficiently again.
Replacing The Door Switch
The door switch tells the dryer when the door is closed. A broken switch may send wrong signals, making the dryer run nonstop. Replacing this switch often solves the problem. It requires removing the dryer panel and unplugging the old switch. Installing a new switch restores normal operation and safety.
Fixing Or Replacing Control Board
The control board manages the dryer’s cycles and power. A faulty board can cause the dryer to ignore door signals. Fixing the board means checking for burned parts or loose connections. Sometimes, full replacement is needed if the board is severely damaged. This repair demands technical skills and proper tools.
Addressing Thermostat Issues
The thermostat controls the dryer’s temperature and timing. A bad thermostat may cause the dryer to run without stopping. Testing the thermostat involves using a multimeter for accuracy. Replacing a faulty thermostat is a common advanced repair. This step helps prevent overheating and saves energy.
