Causes and checks
The exhaust duct is blocked or dirty, or the duct run is too long. Source: Troubleshooting: Operation, p. 52
- Check that the exhaust duct is set up correctly and free of debris, lint and obstructions.
- Check that the outside wall damper opens properly and is not blocked, jammed or damaged.
The load is not sorted. Light items in a load with heavy items can fool the sensor because the light items dry faster. Source: Troubleshooting: Operation, p. 52
- Separate heavy items from lightweight items. Larger and heavier items take longer to dry.
The load contains large and heavy fabrics, which retain more moisture. Source: Troubleshooting: Operation, p. 52
- Split large and heavy fabrics into smaller loads of a consistent size.
The controls are not set for the load. Source: Troubleshooting: Operation, p. 52
- Use the control settings that suit the load. Some loads need a different dry level.
The lint filter needs cleaning. Source: Troubleshooting: Operation, p. 52
- Clean the lint filter before every load. See Clean the lint filter.
- Hold the clean filter up to a light to see whether the screen is dirty or clogged. With high-lint loads such as new bath towels, pause the cycle and clean the filter during it.
A house fuse is blown, a circuit breaker has tripped or the power is out. Source: Troubleshooting: Operation, p. 52
- Reset the breaker or replace the fuse. Do not increase the fuse capacity.
Licensed electrician If the circuit is overloaded, have a qualified electrician correct it.The dryer is overloaded. Source: Troubleshooting: Operation, p. 52
- Divide extra large loads into smaller loads.
The dryer is underloaded. With a very small load on a Sensor Dry cycle, the control cannot sense dryness and may stop too soon. Source: Troubleshooting: Operation, p. 52
- Add a few extra items for proper tumbling, or use a Time Dry cycle, or add some extra wet clothes.
The Energy Saver option is on. It adds an air dry section at the start of the Normal cycle, so no heat is felt at first. Source: Troubleshooting: Operation, p. 52
- If you are using the Normal cycle, turn off the Energy Saver option that is on by default.
