Problems you may notice
• Dryer stops mid-cycle and displays F15 error code
• Clothes are not drying properly or remain damp
• Dryer will not start or complete a drying cycle
• Excessive heat or no heat being generated
• Burning smell or unusual odors during operation
• Error code appears intermittently during different cycles
Possible Causes
• Faulty thermal sensor or temperature probe malfunction
• Heating element failure or reduced heating capacity
• Damaged wiring or loose electrical connections to the thermal sensor
• Lint buildup on or around the thermal sensor affecting readings
• Circuit board or control module failure affecting temperature regulation
• Failed high-limit thermostat preventing proper heat cycling
• Blocked exhaust vent reducing airflow and causing temperature detection issues
Precautionary measures
• Verify the dryer is properly plugged in and the outlet is functioning by testing with another appliance
• Check your home's circuit breaker panel to ensure the breaker for the dryer has not tripped; reset if necessary
• Open the dryer door fully and inspect the lint filter—clean it thoroughly and ensure it sits properly in place
• Examine the exhaust vent area (both inside and outside the dryer) for lint clogs or blockages that could restrict airflow
• Verify the dryer door closes completely and latches securely with no gaps
• Ensure you are not overloading the dryer drum; follow manufacturer guidelines for load capacity
• Check that you are using appropriate cycle settings for the load type
• Unplug the dryer from the outlet or turn off the circuit breaker for 60 seconds, then restore power to perform a full system reset
• If the F15 error persists after these steps, contact a professional appliance repair technician to diagnose the thermal sensor, heating element, or control board issue
