Problems you may notice
• Dryer stops mid-cycle and displays F5 error code

• Dryer runs longer than normal before shutting off
• Dryer may not start or complete any drying cycle
• Error message persists across multiple drying attempts
• Inability to select or run any drying program

Possible Causes
• Blocked or obstructed moisture sensor contacts due to lint buildup
• Damaged or faulty moisture sensor requiring replacement
• Restricted airflow from clogged exhaust vent or ductwork
• Poor electrical connection to moisture sensor circuitry
• Lint accumulation in the dryer drum or air pathways
• Faulty thermal fuse affecting sensor operation
• Malfunctioning control board failing to read sensor signals
• Improper dryer installation affecting venting system performance
• Defective blower wheel reducing air circulation
Precautionary measures
• Verify the dryer is properly plugged into a 240-volt outlet (standard for USA electric dryers) and check that the outlet is functioning
• Inspect the circuit breaker in your electrical panel; reset if it has tripped
• Ensure the dryer door is fully closed and latching completely
• Remove and clean the lint filter thoroughly with a lint brush to remove all trapped fibers
• Check the external exhaust vent opening outside your home to ensure it is not blocked by lint or debris
• Verify the entire exhaust duct from dryer to exterior vent is clear and not kinked or crushed
• Avoid overloading the dryer drum with excessive laundry
• Confirm you are selecting appropriate drying cycles for your load type
• Perform a hard reset by unplugging the dryer from its outlet for 60 seconds, then plugging it back in
• Alternatively, switch off the circuit breaker for the dryer for 60 seconds, then switch it back on
• Run a test cycle after each troubleshooting step to check if the error clears
• If the F5 error code persists after completing all safe checks, contact a professional appliance repair technician to diagnose and repair the moisture sensor or related internal components
