The Frequency Filter is an OEM replacement part for Bosch microwave ovens. Located inside the control panel casing, it prevents electromagnetic interference between electronic circuits. The frequency filter ensures precise cooking settings by filtering out radio waves and high-frequency noise.

Symptoms of a faulty frequency filter include:

• Settings appearing arbitrarily changed or unresponsive  
• Error codes signaling control malfunctions
• Microwave failing to heat or function as anticipated
• Buzzing, crackling, or whining noises emitting from inside

Causes of a bad frequency filter typically involve failures over extended usage. Repeated filtering can degrade or displace sensitive parts interfering with operations. 

Replacing your frequency filter restores reliable cooking and cabinet protection. This genuine Bosch component prevents future issues. Compatible with Thermador, Gaggenau, and select Kenmore microwaves.

This high-voltage capacitor stores and releases energy in the microwave's high-voltage circuit that powers the magnetron. Replacing a failed capacitor can help restore heating performance and reduce humming or breaker trips caused by HV faults. What it does:

• Works with the high-voltage transformer and diode to supply the voltage the magnetron needs for heating
• A weak or shorted capacitor may cause the microwave to run but not heat
• May lead to loud humming/buzzing, a blown internal fuse, or tripped circuit breaker
• Bulging, leaking, or burn marks on the capacitor indicate it should be replaced

• Includes 1 high-voltage capacitor

• Disconnect power by unplugging the unit or switching off the dedicated breaker before service
• High-voltage capacitors can retain a dangerous charge even when unplugged; discharge properly and follow safety procedures
• Document wire routing and terminal orientation before removal; transfer any brackets or clips from the original part
• After installation, ensure no voltage remains on the terminals before reassembly and testing

This turntable ring supports the microwave's glass tray so it turns smoothly for even heating and prevents wobble. Durable rollers reduce friction and keep the tray centered for quiet, reliable operation. What it does:

• Supports and guides the glass turntable so it rotates evenly.
• Replaces worn or broken roller rings that cause the tray to wobble or bind.
• Reduces grinding or scraping noises from a misaligned turntable.
• Helps restore proper tray movement for consistent heating.

• Always unplug the appliance before servicing to avoid electric shock.
• Remove the glass tray, lift out the old ring, place the new ring on the turntable support, then replace the glass tray.
• Handle the glass tray carefully to avoid chipping or cracking; no special tools usually required.

This replacement oven interior lamp provides bright, direct illumination so you can check cooking progress without opening the door. It restores a working oven light when the original bulb is burned out or dim. What it does

• Replaces the oven interior light to improve visibility while cooking.
• Commonly used when the oven light is dark, flickering, or fails to turn on.
• Helps you monitor food without opening the oven door and losing heat.
• Matches the original lamp's fit and function when the part number matches.

• One oven interior lamp.

• Disconnect power to the appliance before replacing the lamp to avoid electrical shock.
• Allow the oven to cool completely before changing the bulb; use gloves or a cloth when handling.
• Remove any protective cover or lens per your owner's manual; replace lamp and reattach cover securely.

This temperature limiter is a safety cutoff that stops power to a heating circuit when temperatures exceed safe limits, protecting the appliance from overheating and potential damage. What it does:

• Interrupts the heating element circuit if internal temperature gets too high
• Prevents overheating-related damage and reduces fire risk
• Can cause no-heat or intermittent heating when failed
• Trip related safety systems or cause the appliance to shut off unexpectedly

• One temperature limiter

• Disconnect all power before accessing or replacing the limiter
• Locate and replace the part per the appliance's service manual or wiring diagram
• Handle terminals carefully; ensure secure electrical connections and correct orientation
• Replace with the exact part number to maintain safety functions

This electronic control board manages dishwasher cycle selection, timing and user-interface signals so the appliance runs the chosen wash programs. It restores responsive controls and proper cycle sequencing when the original board fails. What it does:

• Receives input from touchpads/controls and starts/stops wash cycles according to selected settings
• Controls timers, relays and communications between components for correct wash/drain/heating actions
• Common symptoms: unresponsive buttons, dishwasher not starting, stuck in one cycle, or inconsistent cycle behavior
• Replaces a defective main control that causes erratic or no control function

• Disconnect power at the breaker or unplug the appliance before starting work
• Handle the board by the edges and avoid static discharge; use an ESD strap if available
• Reinstall mounting screws and connector plugs securely; do not force connectors
• Follow the manufacturer's service instructions for setup, diagnostics or any required configuration

This replacement screw secures appliance panels and components at their mounting points. Swap in a new screw to restore a tight, rattle-free fit when the original fastener is missing, stripped, or corroded.

• Fastens the designated panel, bracket, or component in place
• Replaces a missing, stripped, or rusted screw
• Helps address loose panels, gaps, rattling, or misalignment at the mounting point
• Maintains proper assembly integrity after service or vibration

• Disconnect power; shut off water supply if working near plumbing
• Match to the removed fastener and replace one at a time to preserve alignment
• Start threads by hand to avoid cross-threading; use the correct driver bit
• Tighten snugly and avoid overtightening, especially into plastic or thin sheet metal

This replacement screw secures appliance panels, brackets, or internal components. Swap out missing, stripped, or corroded hardware to restore a tight, rattle-free fit and keep assemblies properly aligned for reliable everyday use.

• Fastens panels, brackets, or subassemblies to the appliance frame
• Helps maintain alignment and reduce vibration and rattling
• Direct replacement for a worn, corroded, or missing screw
• Typical symptoms: loose panels/handles, gaps or misalignment, rattling noises, visibly missing fastener

• Disconnect power; also shut off water or gas before servicing
• Match head/driver type and length to the original; start threads by hand to avoid cross-threading
• Reuse any original washers or spacers if present
• Tighten snugly—do not overtighten to prevent stripping threads or damaging plastic mounts

This cable harness routes power and signals between appliance components to restore electrical connectivity and reliable operation. It's a direct replacement harness designed to match the original wiring configuration and connectors. What it does:
