Range Hood Control Board

This Control Unit is an OEM part for Bosch vent hoods. Serving as the central control hub, this unit governs the various functions and settings of the vent hood. 

A common issue with a malfunctioning Control Unit involves electrical malfunctions or component failure.  

Symptoms of a defective Control Unit may include:

• Inoperative fan or lighting functions
• Unresponsive control buttons or settings
• Erratic behavior or intermittent functioning of the vent hood

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

This printed circuit is the appliance's electrical control board that manages timed functions and user commands, restoring responsive control and reliable operation when the original board fails. What it does:

• Controls and routes power to user interface, timers, and functional components
• Replaces a failed control board that causes unresponsive buttons or blank/display issues
• Restores correct timing and electronic control when the appliance behaves erratically
• Helps stop intermittent power loss or unexpected cycle interruptions linked to a bad board

• Disconnect power to the appliance before inspecting or replacing the board
• Handle the board carefully; avoid touching components or connector pins to prevent ESD damage
• Verify wiring and connectors match before final assembly; secure all connections

Electronic control board that manages the range hood's fan, lights and user controls to restore normal operation when the original board fails. Use this direct-replacement board for symptoms like unresponsive buttons, lights that won't turn on, or a fan that won't run. What it does:

• Controls fan speeds, on/off functions and light operation via the hood's user interface
• Processes button/relay signals to activate motors and lighting circuits
• Replaces a faulty board causing intermittent or no response from controls
• Stops erratic behavior caused by failing electronic components

• Disconnect power to the appliance at the breaker before starting work
• Handle the board carefully; avoid contact with circuit traces and use anti-static precautions if available
• Verify the part number on the existing board before installing

The Main Control Board is an OEM component specifically designed for GE range hoods. It serves as the central processor responsible for monitoring and regulating all critical operations of the hood through the precise activation of electronic relays and components. The main control board facilitates programmed lighting and motor speed settings according to sensor inputs.

Symptoms of a bad main control board include:  

• Failure to turn on lights or adjust ventilation levels
• Sensor malfunctions triggering alarms  
• Display errors or inconsistent responses to commands
• Intermittent or dead operations unexplained 

Causes can involve power surges, water damage or worn traces/connections due to age.

This OEM GE replacement is compatible with Hotpoint, RCA and some Kenmore hoods as well.

This electronic power board supplies and regulates voltage to the appliance's control system, helping restore reliable startup and control functions. Replace a damaged board to address intermittent power, no display, or failure to start. What it does

• Regulates and distributes power to the appliance's control modules and user interface.
• Helps restore normal startup when the unit won't power on or shows a blank display.
• Can stop erratic cycling or intermittent operation caused by failed power regulation.
• Works with the control electronics to enable responsive button/display behavior.

• One electronic power board (control PCB)

• Disconnect power at the breaker or unplug the appliance before servicing.
• Handle the board by the edges and avoid static discharge; use antistatic precautions if available.
• Verify harness connections match and seating is secure before reassembly.
