FAQ

Can I use any dryer knob as a replacement?

No, you must use a knob that matches your dryer's model number to ensure proper fit and functionality.

What if the knob is loose but not broken?

Try tightening the knob by hand or using a screwdriver. If it remains loose, consider replacing it.

How do I know if the shaft is broken?

If the knob turns freely but the dryer settings do not change, the shaft may be broken. You will need to replace both the knob and the shaft.

Can I repair the knob instead of replacing it?

In most cases, it is more practical to replace the knob rather than attempt a repair, as knobs are relatively inexpensive.
