Most Frequent Causes for Dryer won't start

Cause 1Door Switch

The door switch activates when the dryer door is closed. On most dryers, the door switch makes an audible clicking sound when it activates. To determine if the door switch is working, try starting your dryer and then listen for the “click.” If the door switch makes a clicking sound, it is probably not defective. If you don’t hear a click, use a multimeter to use the door switch for continuity. If the switch does not have continuity, replace it.

Cause 2Drive Motor

The drive motor turns the drum and the blower wheel to exhaust the air. Before replacing the motor, first check the thermal fuse, start switch, and door switch. If all of these parts are working properly, but the motor is making a humming noise, remove the belt from the motor and check the blower wheel for obstructions. If the blower wheel is clear of obstructions, the dryer motor might be at fault. If you suspect the motor is defective, replace it.

Cause 3Drive Belt

On most dryers, when the dryer belt breaks, the motor will still run, but the drum will not turn. However, some dryers have a switch that shuts off power to the dryer if the drive belt is broken. Check the dryer belt to determine if it is broken. If the belt is broken, replace it.

Cause 4Incoming Power Problem

If you have a gas dryer, unplug the dryer from the wall and plug something else into the outlet to determine if the outlet is working. If you have an electric dryer, check the home circuit breaker or fuses. If the circuit breaker or fuses are working, use a multimeter to test the outlet.

Cause 5Main Control Board

The main control board might be defective. However, this is rarely the case. Before replacing the main control board, check all of the more commonly defective parts.If you have determined that all of the other components are working properly, replace the main control board. (The control board cannot be easily tested, but you can try to inspect it for signs of burning or a shorted-out component.)
