Dryer Is Ticking but Does Not Turn On

This problem usually arises suddenly: You load your dryer with wet clothes, turn the timer and press the "On" button. The dryer fails to start but you can faintly hear the sound of the timer as it ticks off the timing cycle. When troubleshooting the problem, begin with the smaller, more obvious issues and work toward the more complex causes.
  1. How It Works

    • The basic design of a clothes dryer has not altered much since its invention. A motor spins a belt that spins a large drum. A heating element, fueled by electricity or natural gas and controlled by a timer, heats the dryer contents. A properly working timer indicates that the dryer is receiving voltage, so the problem is not likely to be caused by a power outage or insufficient voltage to the dryer. To prevent electric shock in such a case, the dryer should be unplugged from electrical power before any troubleshooting or repairs are attempted.

    Broken Door Switch

    • One of the more common causes for a malfunctioning dryer is a broken door switch. The door switch, a small extension located on the door or within the door cavity, prevents the dryer from running if the switch does not make contact with the terminal. Some switches are plastic with metal prongs. Over time, the plastic dries out and breaks off or the metal terminals become corroded or break away. Check the switch and terminal for signs of scorching or damage.

    Blown Thermal Fuse

    • The thermal fuse is a heat sensitive safety device, a tiny mechanism that "blows" when it senses a surge in electricity or heat. In some dryer models, a blown thermal fuse will merely turn off the heating element, while in others the dryer will cease to function. The location of the thermal fuse depends on the dryer manufacturer. Some manufacturers place the fuse inside the small panel at the front foot of the dryer while others place it behind the dryer in the dryer cabinet. A blown thermal fuse usually indicates overheating from improper dryer venting. The lint screen, ducting and exterior vent should be thoroughly cleaned at the same time the fuse is replaced.

    Broken Belt, Motor or Start Button

    • If the dryer belt is broken, the motor will attempt to spin but the drum will remain still. Newer dryer models are equipped with a sensitive switch near the dryer motor that disables the entire dryer when it senses a malfunction If the belt is in good condition and intact, other causes may be a loose idler pulley or spring. If the motor is broken, the dryer will not start at all. The motor mechanism hinges on several other components, such as the door switch, the thermal fuse and a correctly working start switch, sometimes called the"Push to Start" button. The start switch mechanism is located behind the console panel and can be tested for continuity with an ohmmeter.
