Understanding the Dryer Timer
Before diving into the replacement process, it’s important to understand what a dryer timer does and how it functions within your appliance.
What is a Dryer Timer?
The dryer timer is an electromechanical or electronic device that controls the various cycles of the dryer, such as drying, fluff, and cool-down. It determines how long the heating element runs, when the drum turns, and when the cycle ends. In older models, the timer is usually a rotary dial with a gear mechanism; in newer models, it may be an electronic control board.
Signs Your Dryer Timer Needs Replacement
Common symptoms indicating a faulty dryer timer include:
- Dryer stops mid-cycle or does not advance to the next stage
- Dryer runs continuously without stopping
- Dryer does not start at all
- No response when turning the cycle knob
- The dryer heats but does not tumble
- Unusual noises from the control panel
If you observe these signs, it may be time to replace the timer.
