SAFETY NOTICE: Be sure to disconnect power to the appliance before performing any repairs. If you are not comfortable with doing any voltage checks that might be recommended, please contact your local service provider for repairs. Be aware that there could be sharp edges inside the appliance that could cause cuts or other injuries to yourself or others.
From what youâ€™re describing I suspect the thermal fuse or the belt. First
to the dryer. Follow the instructions below to remove the lower front panel. Use a flashlight to inspect if the belt has come off or not. If the belt is broken the dryer will not start. If the belt is ok then we need to check the thermal fuse with an ohm meter. If the thermal fuse is showing open continuity it will need to be replaced. Before replacing the thermal fuse I recommend having the exhaust venting cleaned or replaced. This model of dryer will shut down due to poor exhaust venting. Other possibilities; even heat control board, motor, door switch or wiring harness problem.
Thermal fuse; 3390719, drum belt; 661570
