Bosch Microwave Electronics

Popular Bosch Microwave Electronics

This magnetron in your microwave creates the radiation needed for cooking or warming your food. It is located inside the main cavity, typically near the transformer or waveguide. When the magnetron becomes defective, your food may not heat up properly or heat up at all. Additionally, buzzing or humming sounds may be noticeable while the microwave is in operation. With a malfunctioning magnetron, your microwave loses its primary function. To remove it, you first need to unplug your microwave from its outlet. Before touching any components, discharge the capacitor by placing a screwdriver, with an insulated handle, across the two terminals of the capacitor. Once the capacitor is discharged, replace the current magnetron by disconnecting it from any wires and removing any mounting screws or clips. This magnetron is sold individually and is supplied directly from the original equipment manufacturer.

Installation Instructions
Joseph from WILTON, NH
Magnitron failed
Over the stove microwave installed in top cabinet row.
1. Unplug device.
2. Two people to remove from wall/cabinet (remove two, large, top mounting screws and rotate entire microwave down and off the wall mount). Should be some wood spacers between top of device and bottom of cabinet.
3. Remove screws from sheet metal cover.
4. Remove one screw holding blowers in place and rotate out of the way, in order to gain access to 2 of 5 screws that hold the magnetron in place.
5. Unplug magnetron and remove the 5 screws.
6. Drop in new magnetron and re-assemble microwave in reverse order (steps 5-3).
7. Two people restore micro to wall/cabinet. Replace wood spacers, re-install two, large mounting screws (finger-tight). Test device. Secure the two large screws.

Store the electrical energy needed by a microwaves high-voltage heating system with this replacement capacitor. During cooking, the capacitor works with the transformer, diode, and magnetron to help create the energy that heats food. A faulty capacitor may be linked to no heat, loud buzzing, or a fuse that blows when cooking begins. However, these signs can also come from other high-voltage components, so proper testing is important. Microwave capacitors may hold a deadly electrical charge even after the power cord is unplugged. For this reason, testing and installation must be completed by a qualified appliance service technician.

Usually found kitchen appliances, this OEM-certified diode cable assembly helps to convert power from the transformer to the magnetron, to heat up your food. A damaged cable assembly will cause your appliance to heat food inconsistently or to not work at all. You might notice a burning smell or a loud buzzing sound coming from your appliance. If you do not replace a broken cable assembly, the components that produce heat in your appliance can overheat and fail. To replace your cable assembly, start by unplugging your appliance from any electrical source. Remove any protective casing from the assembly by unthreading any screws or clips. Disconnect the cable assembly from the transformer and the magnetron with pliers. Reinstalling a new cable assembly requires you to reverse the previous steps. Please keep in mind that this cable assembly is sold individually.

Installation Instructions
GYULA from LIBERTYVILLE, IL
Bosch HMC 80251UC microwave oven combo, unit does not working.
Bosch HMC 80251UC microwave oven combo known for its many problems. Dim LED display and others issues. This was a third round of replacing parts. Unit was working for a week. While in use the unit abruptly quit working agai. I am puzzled what else to replace now.
Replaced door switches three times. I suspect another (green Botton) switch again. The whole unit is heavy and need two people to pull out of the cabinet.
