• Dryer runs but produces little to no heat
• Error code E72 displays on the control panel
• Drying time takes significantly longer than normal
• Dryer may shut off mid-cycle or fail to start

Possible Causes
• Malfunctioning temperature sensor (thermistor) that cannot accurately read dryer temperature
• Failed or failing heating element unable to generate sufficient heat
• Broken or damaged thermal fuse that has tripped due to overheating
• Faulty heating circuit relay or control board component
• Poor electrical connection to the heating element or sensor
• Lint accumulation around the heating element or sensor area
• Wiring damage or loose connections in the heating system

Precautionary measures
• Verify the dryer is properly plugged into a grounded 240V outlet (standard USA electrical specification for electric dryers)
• Check that the circuit breaker for the dryer has not tripped; reset if necessary
• Ensure the dryer door is fully closed and latching completely
• Remove and thoroughly clean the lint filter, checking for lint blockages
• Inspect the exhaust vent on the exterior of your home to confirm it is clear and unrestricted
• Verify that the flexible exhaust duct is not kinked, crushed, or clogged
• Avoid overloading the dryer; ensure clothes load is appropriately sized for your model
• Confirm you have selected the correct drying temperature and cycle setting for your load
• Unplug the dryer from the electrical outlet or turn off the circuit breaker for 60 seconds, then restore power to reset the appliance
• Wait a few minutes and restart the dryer to see if the error clears
• If the E72 error persists after these checks, contact a professional appliance repair technician or appliance repair support service to diagnose and repair the heating element, temperature sensor, or control board
