Parts for Ge PT7800SHASS: Control Panel Parts

This electronic control board manages the microwave's user interface and timing, sending commands to run cooking functions. Replacing a failed board restores responsive buttons, a readable display, and consistent operation when the unit otherwise has power.

• Interprets keypad inputs and drives the display
• Coordinates timing and start/stop of cook cycles
• Sends control signals to operate internal relays for cook, fan, light, and turntable functions
• Common symptoms of a failed board include a blank/flickering display, unresponsive controls, won't start, or random beeping/resets

• Disconnect power at the breaker or unplug before service. Microwaves can retain dangerous high voltage.
• Remove the control panel to access the board; document wire locations and take photos for reference.
• Handle the PCB by the edges and use anti-static precautions.
• Transfer any mounting hardware or wire connectors from the original board; seat all connectors fully before reassembly and test.

The Relay Board is an OEM part for Whirlpool wall ovens. It is an essential electronic component that controls various functions and features of the oven, such as baking, broiling, and self-cleaning cycles.

Causes of a malfunctioning Relay Board range from electrical shorts or power surges that can damage the board's circuitry, to component failure due to age or overheating.  

Symptoms of a bad Relay Board include:

• Inability to start or maintain oven cycles
• Erratic temperature fluctuations or uneven heating
• Error codes indicating a control board malfunction
• Certain oven functions not working correctly or at all

This OEM Whirlpool part is also compatible with Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper and some Kenmore models.

The Encoder Board is an OEM replacement part for GE microwaves, engineered to provide control over the microwave's functions. This component translates user input into digital signals for the microwave's main control board. It allows users to adjust power levels, cooking times, and settings accurately. 

The causes for issues with the Encoder Board can be attributed to electrical faults, such as short circuits or component failures, often resulting from power surges or normal wear and tear. 

Symptoms of a malfunctioning Encoder Board include:

• Difficulty in adjusting settings, which may manifest as unresponsive or erratic control panel behavior.
• The microwave starting or stopping unexpectedly, indicating a miscommunication between the user interface and the microwave's control system.
• Inconsistent cooking results, stemming from the inability to accurately set cooking parameters.

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

The Power Board is an OEM part for GE microwaves. As the main circuit card, it facilitates transmission of high frequency energy to the magnetron tube responsible for efficient cooking.

Causes for replacement include failure of electronic pathways from continual usage, unexpected power surges, or moisture exposure damaging components over time.

Symptoms requiring replacement are:

• Diagnostic error codes displayed
• Power level options locked on high or unavailable
• Magnetron tube malfunctioning or non-functional
• Controls and display segments unresponsive

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

This VFD signal harness connects the appliance control board to the variable-frequency drive, carrying the signals that control motor speed. It restores reliable communication between control and drive so the motor responds correctly. What it does:

• Routes low-voltage control signals from the main control board to the VFD/drive
• Enables proper motor speed commands and feedback for normal operation
• Commonly replaced when intermittent motor response, drive errors, or communication faults occur
• Helps eliminate symptoms like failure-to-start, erratic motor speeds, or fault codes tied to drive communication

• One VFD signal harness

• Disconnect power before servicing to avoid shock or damage
• Inspect connectors and routing; replace if wires or terminals are damaged
• Secure harness away from heat sources and moving parts; match original routing for proper operation

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.

This electronic oven control assembly replaces the main user interface and control board to restore oven function and cycle control. It provides the keypad/display/logic needed for timed baking, broiling, and broil/oven functions. What it does:

• Replaces the oven's main control board and user interface so the oven can receive and follow cooking commands.
• Manages bake, broil, timed cook, and temperature regulation circuits.
• Commonly used when the display is blank, the oven won't heat, buttons or touchpad are unresponsive, or error codes related to control are present.
• Works with the oven's wiring harness and sensors to coordinate heating elements and safety features.

• 1 electronic oven control assembly

• Disconnect power at the breaker before beginning any repair to avoid shock.
• Handle the control assembly carefully to avoid static damage; support the board when unplugging connectors.
• Verify connector locations and wire routing match the original; do not force connectors.

This replacement control knob restores a secure, accurate feel when selecting settings on your appliance. Swap in a new knob to fix cracked, stripped, or missing originals so you can turn the control reliably and keep daily cooking on track.

• Engages the control shaft so you can select heat or function as intended
• Common symptoms: knob spins freely, falls off, feels wobbly, or won't turn the control
• Restores proper indexing with panel markings for predictable operation
• Freshens the look of a worn or damaged control area

• Disconnect power before servicing; for gas appliances, also shut off the gas supply
• Pull the old knob straight off the shaft—avoid prying against the control panel
• Align the new knob with the flat/key on the shaft and press firmly until fully seated
• Verify smooth rotation and correct pointer alignment after installation
