Parts for Ge PSB2200NBB02: 02 - Controller Parts

Display holder bracket for built-in and over-the-range microwaves. Secures the control panel display assembly. Replace if cracked, broken, or missing.

This LED board powers and/or controls interior lighting so the appliance interior is illuminated for easier visibility. Replaces a failed or dim LED module to restore consistent, energy-efficient light in the compartment. What it does:

• Provides

Selector knob or dial stopped working? This encoder board translates rotary control input into signals. Moderate DIY repair requires control panel removal.

Fixes microwave that won't heat or has a dark display. This power transformer converts incoming voltage to power the magnetron and control board.

This relay board controls and distributes power to key components, restoring proper operation when the original board fails. It helps resolve power-routing issues that cause intermittent or non-responsive cooking functions.

• Switches high-voltage loads on/off under control of the main electronics
• Can cause no heat, dead display with power present, or intermittent operation when failing
• May produce clicking without function or blown fuse symptoms if shorted
• Restores consistent power delivery to heaters, fans, or transformers as designed

What's included: 1 relay board assembly Install notes:

• Disconnect power before service; high-voltage components may be present
• Handle the board by edges; avoid touching soldered components
• Photograph wiring and transfer connectors one at a time to matching terminals
• Secure board and verify proper routing before restoring power and testing

Microwave not working or no power? The relay board controls power distribution to the magnetron and fan. Requires control panel removal to install.

A replacement board supporter that secures the appliance control board to the cabinet, helping keep the board stable and positioned away from wiring and chassis. Restores proper mounting to reduce vibration and movement of the control board. What it does:

• Holds and supports the control/PC board to prevent excessive movement or rattling
• Keeps the board spaced from the chassis and wiring to reduce risk of shorting or contact
• Helps maintain stable electrical connections for reliable control operation
• Reduces noise caused by a loose or vibrating control board
• Can prevent further wear on board mounting points and connectors

• Disconnect power to the appliance before beginning any service.
• Handle the control board by its edges and avoid touching components; use ESD precautions if available.
• Remove nearby panels or components as needed for access; retain all fasteners for reassembly.
• If mounting points or fasteners are damaged, inspect nearby parts and replace as required.
