Is This the Right Part?

Common Symptoms

• Knob is cracked or broken.
• Knob spins without engaging the timer shaft.
• Dryer will not start because the timer shaft is not being turned.
• Timer selection cannot be set reliably.
• Timer does not advance after confirming that the dryer is operating in a timed cycle; this may indicate a timer or another control issue rather than the knob alone.

Check Before Replacing

• Disconnect power before inspecting or removing the knob.
• Visually inspect the knob for cracks, splitting, or a worn internal shaft interface.
• With the knob removed, check whether the timer shaft is intact and has the expected flat-sided/D-shaped engagement surface.
• Reinstall the knob and confirm that it seats firmly and turns the timer shaft without slipping.
• If the knob engages the shaft but the timer still does not operate, stop treating the knob as the sole suspected cause and refer to the appliance's model-specific service information.
