# How to Find a Fuse on a Microwave Oven
A microwave consists of multiple components, and if any of these components break, it may cause some features of the microwave to stop working. If the microwave ceases to operate at all, it may be due to one small component: the fuse. The fuse of a microwave may burn out at any time, especially after years of use. When that happens, the microwave will stop running. Replacing the fuse will return the microwave to working order.

Find the clear, cylindrical glass component that looks like a long light bulb. This is the microwave fuse. If the fuse is in working condition, it should be completely clear; a damaged fuse appears black or brown.
