The ceramic fuse is located inside of the cabinet near the entry point of the power cord. Remember to unplug the cord before attempting any repairs. You can check the fuse for continuity with a multi-meter.

What happens if you use the wrong fuse?

Fuses are present to protect the components of the electrical system. Rather than destroying the circuit when there is a surge of power, the fuse blows to protect it. If you use a fuse with the wrong amperage, the fuse won’t blow as intended, damaging the circuit and resulting in a much larger repair bill.
