Hmcn42fs/02 Parts

The Halogen Lamp is an OEM component specifically designed for select Bosch downdraft ventilation hoods. As an illumination source, it provides sufficient light for safe nighttime cooktop use.

Toughened outer casings protect encased bulbs against accidental breakage. Ventilated globe designs dissipate heat for prolonged lamp life while avoiding premature degradation.

Causes requiring replacement relate to cumulative burning hours expended. Direct physical impacts could also crack protective glass allowing water damage that accelerates filament failure. 

Symptoms of a bad lamp include:

• Diminished lighting failing to sufficiently illuminate cook surfaces   
• Flickering or inability to power on through expected lifecycles
• Broken housing fragments exposing live connectors to short circuits

This OEM Bosch replacement halogen lamp is also compatible with Thermador, Gaggenau, and some Kenmore range hoods employing self-contained lighting solutions. Proper bulb installation will restore intended visibility for safe evening meals.
 

The Vent Hood Air Filter is an OEM part for Bosch vent hoods. Located inside the hood cavity, it traps grease, smoke, and other cooking residue to keep the ventilation system functioning optimally. 

Causes of a bad air filter can include normal accumulation of grime over prolonged use without replacement, exposure to excessively greasy cooking vapors, or damage from cleaning.

Symptoms of a bad vent hood air filter include:

• Reduced or inefficient ventilation from the hood  
• Untrapped grease and residue collecting on internal surfaces
• Offensive odors escaping back into the kitchen rather than outside
• Increased noise from the ventilation motor straining 

This OEM Bosch part is also compatible with Thermador, Gaggenau, and some Kenmore models.

This fuse holder secures the appliance's cartridge fuse and helps maintain a reliable power connection. Replacing a worn or damaged holder restores proper fuse seating and reduces risk of intermittent power or electrical faults. What it does:

• Holds the cartridge/inline fuse securely in the appliance's electrical circuit
• Ensures consistent contact to prevent intermittent power, appliance not powering on, or blown-fuse symptoms
• Provides a safe mounting point for the fuse so the fuse can protect the appliance from electrical surges
• Restores reliable connection when the original holder is cracked, loose, or corroded

• Disconnect power (unplug or shut off circuit breaker) before starting any repair
• Access the holder through the appliance service panel; keep track of any screws or brackets
• Replace the fuse with the correct type and rating before reapplying power

This cable harness connects the control board to key components, restoring reliable electrical connections so controls and functions respond correctly. It replaces a damaged or worn wiring harness to resolve intermittent or failed electrical operation. What it does:

• Provides the factory routing and connectors between the control board and appliances components
• Restores lost or intermittent power and signal paths that can cause unresponsive controls
• Helps resolve symptoms like intermittent operation, controls not responding, or specific functions failing to energize
• Maintains proper connector fit and strain relief to prevent chafing and short circuits

• Disconnect all power before starting any repairs to avoid shock or damage
• Handle connectors carefully; match connector shapes and seating to avoid miswiring
• Route the harness following factory clips and tie points to prevent contact with moving or hot parts
• Take ESD precautions and avoid touching circuit traces

The Module Operating is an OEM part for Bosch chimney-style range hoods. As the main control center, it regulates all hood functions including fan speeds, lights, timers, and sensors. Working seamlessly with other internal components, the operating module ensures precise hood operation.

Causes of a bad operating module can include water damage, failure of electronic components over time, or damage from power surges. 

Symptoms of a bad operating module include: 

• Inability to turn hood functions on or off
• Lights not illuminating when selected  
• Preset fan speeds not engaging properly
• Unusual noises or behaviors from internal workings

This Bosch operating module replacement restores full functionality to the hood. It is also compatible with some Thermador, Gaggenau, and Broan-NuTone models. Replacing the module ensures precise performance and conveniences like easy access to controls.

This low-voltage transformer converts standard 120V household power to 12V for halogen lamp circuits, providing the correct voltage and current capacity to run halogen lighting safely and reliably. What it does:

• Steps down 120V AC to 12V AC for halogen lamp operation.
• Supplies up to 60 VA to power one or multiple 12V halogen bulbs per the circuit design.
• Replaces a failed or noisy transformer to restore lighting or stop flicker.
• Protects low-voltage lamp circuitry from incorrect line voltage when installed correctly.

• Disconnect power to the appliance before accessing wiring or the transformer.
• Match wiring and mounting to the original transformer; secure connections with approved splices or connectors.
• Do not exceed the 60VA rating.
