Understanding the Dryer Timer and Its Role
Before diving into the replacement process, it’s important to understand what the dryer timer does and how to identify if it needs to be replaced.
What Is a Dryer Timer?
The dryer timer is an electromechanical or electronic component that controls the timing and sequence of the dryer's cycles. It manages various functions such as:
- Starting and stopping the drum motor
- Activating heating elements
- Switching between different drying cycles (e.g., delicate, heavy-duty, timed dry)
- Controlling features like cool-down and moisture sensing
The timer is typically located behind the control panel and is accessible via the front of the dryer.
Signs That Indicate a Faulty Dryer Timer
If your dryer is experiencing issues, consider these signs that may point to a defective timer:
- The dryer doesn’t start or respond to cycle selections
- The dryer runs continuously without stopping
- The cycles do not advance or get stuck at a certain point
- The dryer stops mid-cycle unexpectedly
- No heat or inconsistent heating during cycles
- Physical damage or corrosion on the timer knob or control panel
If you notice these symptoms, testing the timer is a recommended step before replacement.

Step-by-Step Guide to Replacing a Dryer Timer
This section provides a detailed, sequential process for replacing the dryer timer, applicable to most models.
1. Unplug the Dryer and Access the Control Panel
- Ensure the dryer is unplugged and power is disconnected.
- Move the dryer away from the wall if necessary to access the back or sides.
- Remove the control panel or console cover:
- Usually, screws securing the panel are located at the top or sides.
- Use a screwdriver to carefully remove these screws.
- Gently lift or slide the control panel away, taking note of wiring connections.
2. Take Photos or Make Notes of Wiring Connections
- Before disconnecting wires, photograph the wiring configuration or label wires with masking tape.
- This ensures accurate reassembly.
3. Disconnect the Wiring from the Timer
- Locate the timer component within the control panel.
- Carefully disconnect all wiring harnesses or individual wires attached to the timer.
- Use needle-nose pliers if needed to gently pull connectors off.
4. Remove the Faulty Timer
- The timer may be secured with clips, screws, or a mounting bracket.
- Use the appropriate screwdriver or nut driver to remove these fasteners.
- Gently slide out the old timer from its mounting position.
5. Compare the Old Timer with the New One
- Before installing the new timer, verify it matches the old one in shape, size, and terminal layout.
- Confirm the model number matches your dryer’s specifications.
6. Install the New Timer
- Position the new timer in place, aligning it with the mounting bracket or clips.
- Secure it with screws or fasteners.
- Reattach wiring harnesses or individual wires according to your notes or photos.
- Ensure all connections are tight and secure.
7. Reassemble the Control Panel
- Carefully position the control panel back onto the dryer.
- Replace and tighten screws to secure it.
- Double-check that all wires are properly connected and tucked away to avoid pinching or damage.
8. Test the Dryer
- Plug the dryer into the electrical outlet.
- Turn on the dryer and select different cycles.
- Observe whether the dryer responds correctly, runs through cycles, and heats properly.
- If available, run a test drying cycle to confirm proper operation.
9. Final Checks and Troubleshooting
- If the dryer does not operate correctly, recheck wiring connections.
- Use a multimeter to test the new timer for continuity if suspected to be faulty.
- Consult the owner’s or service manual for specific troubleshooting steps related to your model.
