How to Troubleshoot and Fix a Dryer When Its Timer Is Not Working

If your dryer is having timer problems, it can be frustrating and inconvenient. The timer is an important part of your dryer that controls the duration of the drying cycle. When it malfunctions, your dryer may run for too long or it may stop mid cycle and leave your clothes damp. It's also important to know that a bad timer can be a sign of another problem in the dryer, such as a faulty heating element or thermostat. In this case you may notice alongside the timing issues that your dryer won’t heat.

Troubleshooting a bad timer requires a basic understanding of how the timer and other parts of your dryer work together. In this simple guide, we will discuss some common issues, such as a clogged vent, that can cause your timer to stop working. You will also find the latest 3D images and video tutorials to walk you through inspecting, repairing and replacing the timer, thermostat and other parts that may need repair.

Remember, when troubleshooting any dryer symptom, start by unplugging the dryer from the electrical outlet or turning off the breaker.

Is Your Dryer Vent Clogged?

The most common cause of a clogged dryer vent is the buildup of lint. If the vent is clogged, it can cause the dryer to overheat, which can trip the safety thermostat and cause the dryer to stop running midcycle or to completely shut off. Check the vent to make sure it's clear and clean. You can also prevent any future blockages by cleaning the lint trap and vent regularly.

Common Parts You May Need to Replace

The list of parts below are the most common causes of a dryer drum not spinning. More information, such as part descriptions, 3D renderings, and installation instructions, are available on the individual parts’ pages.

  1. Moisture Sensor Bars
  2. Moisture bars send information about the moisture level in the clothing to the control board (through the sensor board), which works with the timer to set the correct drying time. If the bars are faulty, they will not be able to send this information and your timer will not be able to advance at the appropriate time.
  3. Moisture Board
  4. The moisture board receives signals from the sensor bars and sends information to the control board, to adjust the cycle length. If it is defective, it may not be able to send the information and the timer will not be able to function properly.
  5. Operating Thermostat
  6. The operating thermostat turns the heating element on and off to maintain a consistent temperature during the drying cycle. If it is faulty, it will not be able to control the heating element, and the timer will not know when it is time to start or stop the cycle.
  7. Timer
  8. The timer controls the duration of the drying cycle in a dryer. If the contacts or gears inside the timer are faulty or damaged, you may not be able to control the timer functions.
  9. Electronic Control Board
  10. The control board communicates with the various components of the dryer. If it is defective, it will not be able to send the appropriate instruction to the dryer that it is time to switch on or off.
