Overheating or too hot

When clothes are not drying, follow this order: 1) Check lint screen. 2) Check exhaust hood opens/closes freely. 3) Inspect duct for lint buildup (clean annually). 4) Use 4-inch rigid metal duct. 5) Do not overload (1 wash load = 1 dryer load). 6) Separate heavy and lightweight items. 7) Reposition bulky items for even drying. 8) Check washer is extracting adequate water. 9) Load not too small or too large to tumble. 10) Turn off Eco Dry option. Most 'not drying' complaints are venting or loading issues, not component failures.

Do not replace the PCB assembly based on guesswork. Follow the complete trouble diagnosis procedure before concluding that the PCB is faulty. The manual explicitly warns against replacing PCB assemblies by wrong diagnosis. Test all related components and wiring before ordering a new board.

This platform supports both DUAL and SINGLE heater configurations. DUAL heater (240V, 3700~1500W): 13 Ohm between PIN 2-3 and 34 Ohm between PIN 1-2. SINGLE heater (240V, 5300W): 10 Ohm between PIN 1-3. With the DUAL heater, one element can fail while the other works, resulting in reduced heating rather than complete failure. Always test both pins on DUAL models.

Danger: High voltage is present on the PCB. Before commencing with tests or any repair activity, the appliance must be disconnected from the supply. Once isolated, protection must be provided to prevent the appliance becoming live during testing and repair. Never touch PCB components while the dryer is plugged in.
