Determining whether a microwave oven fuse is blown involves performing a continuity test with a digital multimeter. First, unplug the microwave from the wall outlet and wait several minutes for high-voltage capacitors to discharge safely. Second, remove the outer metal cabinet housing and locate the fuse holder near the power cord entry or control board. Third, pull the fuse out of its plastic clips and test it with a multimeter set to the ohms or continuity setting. You can troubleshoot microwave electrical faults safely. You can verify that your fuse is blown when the multimeter registers an open circuit (OL) with zero continuity, confirming that you must replace the blown fuse with an identical amp rating to restore power.
