Fuses are really just wires that are designed not to last, but their purpose is to prevent damage to more valuable electrical equipment or prevent fires (especially in homes) caused by power surges. thermal fuse not blowing are low, but the chances both won't blow are miniscule, and therefore worth the few cents that a second thermal fuse is gonna cost. To test the thermal fuse, remove the wire or wires from one end of the fuse, then touch one of the meter probes to each of the terminals. To test the fuse for continuity, you will need to disconnect one of its terminals and check it with multimeter. Then place the leads on each terminal. You can disconnect these wires by gently pulling them away from the fuse. The thermal fuse that control the magnetron can completely shut down the microwave. Most microwave fuses do not look any different after they are blown. The thermal fuse is simple to check if you have a voltmeter that checks continuity. But I assume the same applies. If the fuse can be removed from the circuit, then the easiest way to determine if it has blown is a continuity test. This is located in the area of the meter with the omega symbol ( ) The reading should be close to 0 ohms or closed. Impedance goes up when temperature goes down. If the reading is open or OL, the thermal fuse is bad. It becomes open while temperature reaches over its rated temperature. The thermal fuse cannot be reset—if the fuse is blown, it must be replaced. The thermal fuse assembly has been pre-assembled with the fise and bracket whereas the thermal fuse would require the removal of the assembly, as well as removing the "rivets" ("They are really unusual … When this occurs, it will cause the fuse to overheat and blow due to heat build-up. A cheap one will work just fine for this test. Answer Danielle, The DC96-00887C thermal fuse assembly and the DC47-00015A thermal fuse are in short, the same part. Otherwise, set it to the lowest Ohm setting.
