632693R Nordyne DOOR SWITCH

Normal stocking item

The 632693R Nordyne Door Switch is an OEM safety component used in many Nordyne, Intertherm, and Miller furnace models. This switch automatically interrupts power when the blower door or access panel is opened, helping protect both the equipment and the technician during service. If your furnace won’t run with the door closed—or continues running with the door open—this switch is a common replacement point.
