The door switch is a safety device that allows the machine to tumble only when you close the door. If the appliance doesn’t start when the door is closed, it indicates that door switch is damaged. The switch is typically located behind the front panel. You can use a multimeter to check the continuity of the switch. The test must be conducted between the terminals marked “NO” and “C”. The reading of the trial must be zero ohms when the button is depressed.

Thermal Fuse

The fuse is a safety device that prevents overheating. When the temperature inside the machine becomes too hot, the fuse interrupts the power supply to the motor rendering the dryer inoperable. The fuse is about an inch long and is attached to the body of the machine. Some dryers may have more than one fuse to prevent damage to the heating element and blower.

Rotary Switch

The start or rotary switch is located on the central console of the dryer. The switch sends power to the motor which starts the tumbling. If the switch is defective, the dryer will not start. Checking the condition of the switch is easy. All you need is a multimeter to test the continuity.

The drive motor turns the drum and the blower of the dryer. If the motor is defective, the dryer will not start. At times, it may produce a humming sound, which indicates that the switch or winding is bad. To check the motor, you must remove the drum and the front panel.
