Magnetron

Fix microwave not heating or loud humming noise with this magnetron. Generates electromagnetic waves to cook food. Moderately difficult repair.

Microwave not heating food? A failed magnetron is the most common cause. This high-voltage tube generates microwave energy to heat and cook food properly.

Microwave won't heat or makes humming noise? This capacitor works with the magnetron to generate heat. Moderate difficulty repair, 30-45 minutes.

Microwave won't heat but runs and hums? A failed magnetron is the likely cause. This part generates microwave energy. DIY repair takes about 2 hours.

If your microwave isn't heating food or heats unevenly, the magnetron may have failed. This high-voltage tube generates microwave energy for cooking.

Microwave not heating? This magnetron generates microwave energy to cook food. Moderate DIY repair—requires disassembly and careful handling of parts.

Microwave not heating? This magnetron generates microwaves to heat food. Replacing a faulty magnetron restores heating and stops cooking failures.

Microwave won't heat? A faulty capacitor often causes no heating or weak performance. This high-voltage capacitor restores full power. Moderate DIY.

Microwave not heating food? The magnetron generates microwaves for cooking. Moderately difficult repair requiring high-voltage precautions.

Microwave not heating or takes too long to warm food? This magnetron generates the microwaves that cook your food. Moderate repair difficulty.

Fix a microwave that won't heat but runs normally. This magnetron generates the microwaves that cook your food. Professional repair recommended.

Microwave not heating or taking too long to cook? This magnetron generates the microwave energy needed for proper heating. Moderate DIY repair.

This TH capacitor is an electrical control-circuit capacitor used on compatible Bosch appliances to help stabilize voltage and filter electrical noise for reliable control-board operation. Replacing a failed capacitor can address intermittent control issues. What it does

• Stabilizes control-board voltage and helps filter electrical noise that can cause erratic behavior.
• Supports reliable startup and operation of control circuits.
• Common symptom link: intermittent or unexplained control-board errors, erratic or non-responsive controls.
• Common symptom link: appliance displays control or error codes related to electronics or intermittently fails to start.

• Disconnect power to the appliance at the breaker before servicing to avoid shock.
• Discharge any capacitors and allow boards to sit before touching components; use appropriate ESD precautions.
• Only replace with the exact part number; confirm orientation and connector fit before reassembly.

This main electronic control board assembly manages the refrigerator's core functions so the unit responds correctly to user inputs and cycles components for cooling and defrost. Replacing a failed board restores normal control and operation. What it does:

• Manages compressor, fans and defrost cycles by sending signals to subsystem components
• Interprets front-panel inputs and adjusts settings and modes
• Controls display/status indicators and error reporting for diagnostics
• Helps regulate cooling behavior when functioning correctly
• Commonly linked to symptoms like unresponsive controls, incorrect temperatures, or erratic cycles

• One main control board assembly

• Disconnect power to the appliance before starting to avoid shock or damage
• Handle the board by edges and avoid static discharge; use proper ESD precautions
• Verify connectors are fully seated and routed as originally installed; photograph wiring before disassembly
• After installation, restore power and confirm proper operation of controls, display and cooling functions
