✅ Cross Reference Information

Common Symptoms

• Dryer overheats
• Dryer does not heat or produces insufficient heat
• Dryer takes too long to dry
• Dryer may stop heating too soon or fail to maintain normal cycling temperature

Check Before Replacing

• Disconnect electrical power before servicing and allow the dryer to cool.
• Verify that the lint screen, exhaust duct, and outside vent are clear; restricted airflow can also cause overheating or poor drying.
• Inspect the thermostat wiring and terminals for loose, damaged, or heat-discolored connections.
• With power disconnected and the wires removed from the thermostat, check continuity according to the appliance service information and the specific terminal pairs for this five-terminal design.
• Do not condemn the thermostat from symptoms alone; verify related airflow, heating, thermal-limit, ignition, and control components as applicable to the dryer.
