Dryer shows E14 and may not heat or may shut down; often related to safety thermostat or thermal fuse on some models.

Safety first: Disconnect power and allow the dryer to cool fully before testing thermostats or fuses.

E14 indicates a critical over-temperature safety device has opened.

• Access heater and exhaust area: Remove the rear panel to reach the heater housing and exhaust duct.
• Test thermal fuse and safety thermostat: With a multimeter, check each device for continuity. Any open device must be replaced; they are not resettable.
• Investigate cause of overheating: Check lint filter, internal ducts, and external vent (if vented) for heavy lint buildup or obstructions. Clean thoroughly.
• Inspect heater relay and wiring: If the heater remains energized when it should be off, the relay on the control board may be stuck closed. This can cause repeated fuse failures and requires control board replacement.
• Replace failed safety devices: Install OEM-rated thermal fuse and thermostat. Do not bypass or substitute with incorrect ratings.
• Test operation: Reassemble, restore power, and run a test cycle while monitoring temperature. If E14 recurs, seek professional service to check the control board and heater assembly.
