Problems you may notice
• Dryer stops mid-cycle and displays F13 error code
• Dryer will not start or begin heating
• Drum may not rotate when power is applied
• No heat production during drying cycles
• Error code appears immediately after selecting a drying program
• Dryer may shut off automatically during operation
Possible Causes
• Faulty thermal sensor or thermistor component failure
• Thermal fuse blown due to restricted airflow or overheating
• Loose or disconnected thermal sensor wiring connections
• Restricted lint or debris blocking airflow to temperature sensor
• Defective temperature control board or circuit malfunction
• Clogged exhaust vent reducing proper airflow and causing sensor errors
• Power supply issues affecting sensor detection circuits
• Damaged or corroded sensor connectors
Precautionary measures
• Power cycle the dryer: Unplug the unit from the electrical outlet or switch off the circuit breaker for 60 seconds, then restore power and attempt to restart
• Verify the dryer is plugged in securely and the outlet is functioning properly by testing with another appliance
• Check your home's circuit breaker panel to ensure the breaker serving the dryer has not tripped; reset if necessary
• Inspect and clean the lint filter thoroughly before each load
• Clean the lint trap housing and remove any accumulated lint or debris
• Verify the dryer door closes fully and latches completely
• Check that the exhaust vent hose is not kinked, crushed, or clogged
• Ensure the outdoor exhaust hood flapper opens freely when the dryer runs
• Do not overload the dryer drum; use appropriate load sizes for proper airflow
• Verify you are selecting appropriate drying cycles without modifications
• Allow the dryer to cool for 30 minutes before attempting to restart if it shut down during operation
• If the F13 error code persists after completing these checks, contact a professional appliance repair technician or appliance repair support service to diagnose and repair the thermal sensor system
