Parts for Kitchenaid KMBS104EBL03: Oven Interior Parts

The Fuse is an OEM component for Whirlpool microwaves. As a critical safety device, it protects circuits from power surges or overloads that could damage internal electronics. 

The fuse properly calibrates electrical flow through the appliance, preventing excessive currents from traveling between high and low-voltage systems. Its compact design installs discretely but is easily accessible for replacement when needed. 

Causes for blown fuses include voltage spikes from power outages, faulty door interlocks energizing the magnetron with the door open, or short circuits due to loose wires or water intrusion over time.

Causes of a bad fuse can include:

• Repeatedly blowing when the appliance is in use  
• No power to any microwave functions
• Tripped circuit breakers upon turning on the microwave
• Discoloration or physical damage to the fuse body

Compatible with microwave models from Maytag, Magic Chef, Admiral, and more for consistent, worry-free operation.

This block-style fuse holder secures and connects the appliance fuse to the wiring harness, restoring a safe electrical connection and thermal protection. Use it when the original fuse block is cracked, corroded, or no longer holding the fuse securely. What it does:

• Holds and connects the appliance fuse to the wiring harness so the thermal/overload fuse can function.
• Restores reliable electrical contact when the original block is cracked, melted, or corroded.
• Addresses symptoms such as intermittent power, no heat, or appliance not starting when caused by a bad fuse connection.
• Works with the existing fuse and wiring—does not replace the fuse itself.
