Use these checks when the dryer will not start, will not heat, or is drying much more slowly than expected. Only the causes and fixes listed here are supported by the manual.
Possible cause: - House fuse is blown, circuit breaker has tripped, or a power outage has occurred.
What to do: - Reset the circuit breaker or replace the fuse. - Do not increase fuse capacity. - If the problem is a circuit overload, have it corrected by a qualified electrician.
Possible causes: - House fuse is blown, circuit breaker has tripped, or a power outage has occurred. - Gas supply or service is turned off. - Energy Saver option is selected.
What to do: - Reset the circuit breaker or replace the fuse. Do not increase fuse capacity. - If the problem is a circuit overload, have it corrected by a qualified electrician. - Confirm that the hose gas shutoff and the shutoff valves of the dryer are both fully open. - Even if gas is not supplied to the appliance, it will run and no error codes will display. Verify that other gas appliances in the home are working normally. - If using the Normal cycle, deselect the Energy Saver option that is selected by default. - This option reduces energy use by adding an air dry section to the beginning of the cycle. - It is normal to feel no heat at the beginning of the cycle while in Energy Saver mode.
Possible causes and actions:
Exhaust ducts are blocked, dirty, or the duct run is too long - Confirm that the exhaust duct is properly configured and free of debris, lint, and obstructions. - Make sure that the outside wall damper can open properly and is not blocked, jammed, or damaged.
Load is not properly sorted - Separate heavy items from lightweight items. - Larger and heavier items take longer to dry. - Light items in a load with heavy items can fool the sensor because the light items dry faster.
Large and heavy fabrics are loaded - Heavy fabrics take longer to dry because they tend to retain more moisture. - To help reduce and maintain more consistent drying times for large and heavy fabrics, separate these items into smaller loads of a consistent size.
Dryer controls are not set properly - Use the appropriate control settings for the type of load you are drying. - Some loads may require an adjustment of the dry level setting for proper drying.
Lint filter needs to be cleaned - Remove the lint from the filter before every load. - With the lint removed, hold the filter up to a light to see if it is dirty or clogged. - With some loads that produce high amounts of lint, such as new bath towels, it may be necessary to pause the cycle and clean the filter during the cycle.
House fuse is blown, circuit breaker has tripped, or power outage has occurred - Reset the circuit breaker or replace the fuse. - Do not increase fuse capacity. - If the problem is a circuit overload, have it corrected by a qualified electrician.
The appliance is overloaded - Divide extra large loads into smaller loads for better drying performance and efficiency.
The appliance is underloaded - If you are drying a very small load, add a few extra items to ensure proper tumble action. - If the load is small and you are using SENSOR DRY cycles, the electronic control cannot properly sense the dryness of the load and may shut off too soon. - Use MANUAL DRY cycles or add some extra wet clothes to the load.
Energy Saver option is selected - If using Normal cycle, deselect the Energy Saver option that is selected by default. - This option reduces energy use by adding an air dry section to the beginning of the cycle. - It is normal to feel no heat at the beginning of the cycle while in Energy Saver mode.

No. The manual says not to overload the dryer. Overloading reduces drying performance and energy efficiency, and clothes need room to tumble and dry properly.
No. Turning the controls to OFF does not disconnect the appliance from the power supply. Disconnect power by unplugging it or switching off the house fuse or circuit breaker before cleaning or servicing.
Yes, if the Energy Saver option is selected. The manual says this option adds an air-dry section at the beginning of the cycle, so it is normal to feel no heat at first.
These codes mean the exhaust system is too long, has too many turns or restrictions, or the house exhaust system is blocked.
Possible causes listed are a blown house fuse, a tripped circuit breaker, a power outage, the gas supply or dryer shutoff valves being off, or the Energy Saver option being selected. Make sure the gas shutoffs are fully open, and if using the Normal cycle, deselect Energy Saver.
The manual lists a blown house fuse, a tripped circuit breaker, or a power outage as possible causes. Reset the breaker or replace the fuse. Do not increase fuse capacity. If the problem is a circuit overload, have it corrected by a qualified electrician.
