Fuse

If your microwave is not turning on it could be due to your fuse needing to be replaced. This part protects the microwave by shutting it off if there is an electrical surge. This fuse is just over an inch long, is metallic on both ends and ceramic in the middle. Before beginning this repair, unplug the appliance and wait a few minutes before starting. Remove the outer cabinet which is held in place with two screws. You will then locate the power cord which will lead you to the fuse holder. Determine if the fuse has blown. Using an ohmmeter, you should be able to figure out if it has blown. A proper reading is zero ohms, if it reads as anything else then your fuse has in fact blown. Simply snap the old fuse out of place and place the new one in.
