Bosch 658490 Magnetron Microwave Replacement Part

Product Description

The BOSCH 658490 is a genuine OEM magnetron designed to restore heating function in Bosch microwave ovens. The magnetron is the core component responsible for converting electrical energy into high-frequency microwave radiation, which excites water molecules in food to generate heat. This part is the correct replacement when a microwave runs but fails to heat, produces loud humming during operation, or emits burning odors. As a factory-specified component, the 658490 is built to meet the original design tolerances for fit and function in compatible Bosch microwave units.

This magnetron is intended for use in residential Bosch microwave ovens where the original magnetron has failed or degraded. Common failure indicators include the unit powering on with no heat output, audible buzzing or arcing sounds during a cycle, or visible damage to the existing magnetron assembly. A qualified appliance technician or experienced service professional typically performs this replacement as part of a microwave heating system restoration.

Key Features

• Genuine OEM Bosch part ensuring correct fit for compatible microwave models
• Restores full heating and cooking function when original magnetron has failed
• Addresses no-heat, loud humming, and burning odor failure symptoms

Compatibility

Designed as an OEM-style replacement magnetron for compatible Bosch residential microwave ovens. Verify fitment against the specific model number of the unit being serviced before installation.

Installation Notes

Magnetron replacement should be performed by a qualified appliance technician. Always disconnect the microwave from its power source and discharge the high-voltage capacitor before beginning disassembly, as stored charge presents a serious shock hazard even after power is removed. Remove the existing magnetron assembly, transfer any necessary hardware, and secure the replacement unit before reconnecting wiring and restoring power. Follow all applicable local electrical codes during service.
