Where are fuses in microwaves?
The most common cause of an overheating magnetron is when too much energy is reflected back into the device. This can happen when you run your microwave empty (something you should never do), or if the turntable has been removed.
They function as safety devices to disconnect the current to the heating element in case of a malfunction (such as a defective thermostat) that would otherwise allow the temperature to rise to dangerous levels, possibly starting a fire.
Fuses are located in many places inside the microwave, including the top, side, and behind the vent grille. Using the wiring diagram can help you locate the appropriate fuse. Once you have located the fuse, remove any necessary wires and fasteners to free it from the microwave.
The fuse is located under the plastic grill at the top of the microwave. It’s held on by two screws. Once you’ve removed the screws and taken off the plastic grill, you go to the right side of the microwave and remove another screw that holds a small metal grill in place.
If your microwave is relatively new and the repair costs less than replacing it, the fix is worth it. But are microwaves worth repairing if something major is broken? Probably not. Consider getting a replacement appliance for about $100, which should work for 7 to 10 years.
One little-known feature of almost every brand of microwave is the locking mechanism.
Microwave ovens use one or more thermal cut-outs, sometimes called thermal fuses, to protect the oven from overheating. They are located inside of the cabinet, often near the oven cavity or the magnetron.
The most common reasons why a microwave is not heating up are a defective high voltage diode, the door switch, the magnetron or some other minor component. A qualified technician can usually figure out which piece needs replacement and will do so safely, even if replacing the part requires opening the machine cavity.
The microwaves require a 120 volt, individual, properly grounded branch circuit with a 3 prong grounding type receptacle protected by a 15 or 20 amp circuit breaker or time-delay fuse.
Fuses are located in many places inside the microwave, including the top, side, and behind the vent grille. Using the wiring diagram can help you locate the appropriate fuse. Once you have located the fuse, remove any necessary wires and fasteners to free it from the microwave.
