Is This the Right Part?

Common Symptoms

• Microwave has no display or does not operate after a power surge.
• Fuse blows repeatedly when the microwave is started.
• Circuit breaker may trip when the microwave is started, although other components such as door switches or the magnetron may also be involved.

Check Before Replacing

• With power disconnected, inspect the fuse for an open or visibly damaged element; replace only with the specified 125-volt, 20-amp fuse.
• If the replacement fuse blows immediately or repeatedly, have the door switches, magnetron, wiring, and related components professionally diagnosed rather than repeatedly replacing the fuse.
• Verify the appliance model number before ordering because microwave fuse fitment is model-specific.
