Parts for Ge PSB9100DF3BB: Control Parts

This control knob restores safe, easy operation of a stove or range control. It replaces a cracked, melted, or missing knob so you can adjust burners or oven settings with a secure grip and clear feel. What it does:

• Fits onto the appliance control shaft to select burner or oven settings
• Replaces damaged, loose, stripped, melted, or missing knobs
• Provides a firm, tactile grip for precise control
• Helps prevent accidental changes by seating securely on the shaft

• Disconnect power (and gas, if applicable) before servicing the appliance

• Align the knob with the control shaft splines and push firmly until fully seated
• If the knob does not install easily, verify shaft alignment and do not force.

The Microwave Power Supply Board is an OEM replacement part for GE microwaves. As the board that receives power from the outlet and safely distributes it to other electronic systems, it plays an important role in powering microwave functions.

Causes of a bad power supply board include failures in its electronic components over many years of operation. Defects can disrupt or prevent stable power distribution.

Symptoms of a bad power supply board include:

• The microwave not receiving any power and failing to turn on
• Inconsistent or fluctuating power output causing irregular cooking results
• Buzzing or cracking noises emanating from the board

This GE OEM replacement part is also compatible with Hotpoint, RCA, and some Kenmore models.

The Digitron is an OEM part for GE microwaves. It is an essential component of the microwave's control board, displaying settings, cooking times, and other information on the microwave's digital display.

Over time, the Digitron can fail due to electrical issues, exposure to moisture, or normal wear and tear. If the Digitron is malfunctioning, it can affect the readability of the display or the functionality of the control panel.

Symptoms of a bad Digitron include:

• The display being dim or completely dark
• Inaccurate or incomplete information shown on the screen
• Flickering or intermittent display issues
• Unresponsive control buttons linked to the display

This GE replacement part is also compatible with Hotpoint, RCA, and some Kenmore models.

This main control board is the appliance's primary electronic control module that manages cycles, user inputs and timed functions so the unit responds correctly to settings and commands. Replacing a failed board restores normal electronic control. What it does:

• Receives input from the user interface and sends control signals to components
• Manages timing, sequencing and safety interlocks for normal operation
• Common symptom: display or controls are unresponsive or the unit won't start
• Common symptom: erratic or incorrect cycle behavior, or intermittent power to functions

• One main control board

• Disconnect power before servicing to avoid shock; verify power is off at the breaker
• Handle the board by its edges and avoid contact with components or connector pins
• Compare new board to the removed board to confirm connector locations before installing
• Transfer any mounting hardware, brackets, or cable retainers from the old board exactly as removed

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.

The Relay Board is an OEM part for GE microwaves. It controls the passage of proper voltage levels for various microwave components during operation.

Installed internally, this board transmits power signals to run the magnetron, fan, and lighting systems as directed by the selected cooking settings. Precise switching of voltages is required for consistent and balanced microwave radiation. 

Symptoms of a faulty relay board include:  

• Intermittent or unpredictable power level adjustments
• Magnetron fails to turn on or fluctuates excessively
• Light not illuminating properly  
• Fan speed irregularities
• Microwaves not properly heating foods

Causes can be damage from liquid intrusion, heavy usage over time stressing the relays, or component failures within the board itself.

Replacing with this genuine OEM GE part restores optimized power routing to maintain consistent microwave functions. Compatible models also include some Hotpoint, RCA, and select Kenmore products.
