Supco mw9458 Microwave Interlock Switch 125/250V 16A

Product Description

The SUPCO mw9458 is a microwave door interlock switch that monitors the position of the door latch and signals the electronic control board whether the door is open or closed. Rated at 125/250 volts and 16 amps, this switch is a direct replacement component for microwave ovens requiring latch-position feedback to the main control. It is typically installed by appliance service technicians during door switch diagnostics or control board-related repairs.

This interlock switch is suited for residential microwave oven applications where the door safety circuit requires reliable open/close status reporting. It cross-references to OEM part number W10269458. Installers working on units with intermittent start failures, no-power conditions, or door latch faults commonly replace this switch as part of a systematic door switch circuit diagnosis.

Installation Notes

Microwave door interlock switches must be replaced by a qualified appliance service technician. Always disconnect the microwave from its power source before beginning any disassembly. Microwave ovens can retain lethal high-voltage charges in the capacitor even after being unplugged — capacitor discharge procedures must be followed before touching internal components. Verify switch orientation and terminal connections match the original before reassembly.
