Is This the Right Part?

✅ Cross Reference Information

Common Symptoms

• A selected control setting does not register or change as the rotary control is turned.
• Rotary-control operation is intermittent or inconsistent.

Check Before Replacing

• Disconnect power before accessing the control area.
• Confirm the symptom occurs specifically when the rotary control is operated; a no-start condition alone does not identify this switch because the listed models use a separate start switch.
• Inspect the external knob/control area for binding, damage, or abnormal movement without forcing it.
• With power disconnected, compare the switch connector and terminal layout to the replacement part and the appliance wiring information for the exact model.
• If qualified to use a meter, test switch contact operation only with the dryer unplugged and the switch electrically isolated, following the exact model wiring diagram.

Installation Notes

• Disconnect electrical power before servicing the dryer.
• Verify the dryer model and part number before installation; do not substitute a visually similar rotary switch.
• Document connector positions before disconnecting the original switch, and reconnect terminals to their original locations.
• Ensure the included seal is positioned as supplied and that the control/knob moves freely after reassembly.
• Reassemble all control-panel covers and guards before restoring power.
