How to Replace a Dryer Timer
The timer manages the various dryer functions. The timer's internal cams open and close switches or contacts to operate the various electro-mechanical components in the dryer (mainly the drive motor and the heating element). A small motor on the back of the timer advances the dial during the cycle to show how much time remains. If the dial doesn't advance or the timer doesn't shut off the components, follow the steps in this dryer repair guide to replace it with the manufacturer-approved replacement part.

Step 2: Remove the control knob
Pull the timer control knob off of the timer stem on the front of the control panel.
Step 3: Remove the back panel
Move the dryer forward and use a 1/4" nut driver to remove the screws from the back panel. Remove the back panel from the dryer and set it aside.
Step 4: Remove the timer
Note the location of wires attached to the back of the timer before removing them. Label the wires or take a digital picture so you know how to reconnect them later. Remove the wires from the back of the timer. Remove the mounting screws and then remove the timer.
Step 5: Install the new timer
Insert the new timer in the control panel and secure it with the mounting screws. Attach the wires to the new timer, following the labels or digital photograph.
Warning: For safety and to avoid damage to the new timer, the wires must be properly connected. If you are unsure how to connect the wires, have a service technician complete this repair.
Step 6: Reattach the back panel
Position the panel on the back of the console. Line up the mounting screw holes, insert the mounting screws and tighten them firmly.
Step 7: Reinstall the control knob
Push the control knob onto the stem of the new timer.
Step 8: Restore power to the dryer
Plug the dryer into the wall outlet. If it's a gas dryer, turn on the gas supply to the dryer.
