Remove, clean and reinsert the dryer’s lint screen. Clean the lint screen after every load.
Look at the controls and see if you selected air dry. Air dry does not provide heat for drying a regular load; choose another setting.
Check how many clothes you’ve put in the dryer. If the load is too large, it won’t dry properly. Don’t overfill the dryer.
Remove the fabric softener sheet. It may be blocking the grill. If using a softener sheet, use only one, and discard after use.
Turn up the heat to the room if the temperature is below 45 degrees Fahrenheit. The dryer won’t dry properly if ambient temperatures fall below 45 F.
Measure the area around the dryer. The rear of the dryer requires about 5 inches of air space, while the front needs about 1 inch. If the dryer is located in a closet, you may not have sufficient air space around the appliance.
Inspect the exhaust vent. It won’t work properly if it is too long or has too many turns. It typically needs to be about 4 inches in diameter.
Check the dryer door to see if it is closed. Something may be blocking the door.
Push the start/pause button and hold it to see if the dryer begins running. If you fail to push the button hard or long enough, the dryer won’t start.
Check the power supply. Make sure the appliance is plugged into the power source. If it is an electric dryer, you need a 240-volt power supply. You may have the wrong type of fuse; it should be a time-delay fuse. Check to see if the household fuse is blown or the circuit breaker tripped.
