Compatibility Notes

Fits many washers and dryers from Whirlpool, Maytag, and related brands that use this style of selector knob.
-
Before ordering:
-
Verify your appliance’s model number and serial number, found on the machine’s frame or cabinet.
-
Compare your existing knob: check shaft diameter, clip/screw type, knob outer diameter and style/markings.
-
If the issue stems from a damaged control board, shaft assembly or internal mechanism rather than just the knob, simply replacing the knob may not fully restore functionality.
