Parts for Kitchenaid KBMS1454RSS0: 05 - Oven Interior Parts

This line fuse protects the appliance's incoming power circuit by opening if an overload or short occurs. Replacing a blown fuse can help restore power once the underlying issue is corrected, preventing further damage to sensitive components.

• Interrupts line voltage when excessive current or a short circuit is detected
• Typical symptoms: unit completely dead, no display or interior lights, won't start or run
• Fuse tests open/no continuity with a multimeter when blown
• A blown fuse often points to another fault that must be addressed

• Disconnect power at the breaker/unplug before servicing; microwaves contain high-voltage parts that can retain a dangerous charge even when unplugged
• Replace only with the same type and rating as the original fuse
• Ensure the fuse seats firmly in its holders; do not bypass or jumper a fuse
