Jenn-Air Refrigerator Control Board

This inverter box is the electronic module that conditions and routes power to the refrigerator compressor, helping restore variable-speed compressor operation and consistent cooling when the inverter has failed. What it does:

• Regulates and converts power for the compressor's inverter drive to support variable-speed operation.
• Replaces a failed inverter module that can cause the compressor not to start or to run intermittently.
• Commonly used when the refrigerator runs warm, cycles abnormally, or displays inverter-related errors.
• Houses the control electronics for compressor power management.

• Always disconnect power before servicing the appliance to avoid shock.
• Access may require removing the rear or control housing panels; note wire routing and connector positions before disconnecting.
• Handle as an electronic component: protect from moisture, impact, and static discharge.

This 5-button dispenser control board runs the refrigerator's ice/water dispenser user interface. Replace it to restore button response, indicator lights, and proper dispenser selections when the original board is unresponsive or erratic.

• Interprets dispenser keypad inputs and communicates selections to the appliance's control system
• Drives the dispenser panel's indicator lights and status feedback
• Coordinates ice and water dispensing functions based on user commands
• Common symptoms include no response to buttons, dispenser lights/indicators not working, inability to change selections, or intermittent/erratic UI behavior

• Disconnect power before servicing; use ESD protection when handling electronics
• Remove dispenser trim/panel to access the board; release locking tabs and unplug the wire harness
• Transfer any reusable overlay or mounting hardware from the original board if applicable
• Seat connectors fully, reassemble, and test dispenser functions before finalizing

This compressor board kit replaces the compressor's control board to restore reliable compressor start and run behavior. It helps address compressor start failures and intermittent cooling so the appliance can return to normal operation. What it does:

• Replaces the compressor control/relay board that manages compressor startup and operation.
• Can stop or reduce symptoms such as the compressor not starting, repeated clicking/humming, or intermittent cooling.
• Provides the electrical interface between the compressor and the appliance power/control circuits.
• Helps isolate electronic control failures from mechanical/sealed-system issues.

• Disconnect power to the appliance before beginning any service.
• Handle the circuit board by its edges and avoid static discharge; use basic hand tools.
• Verify harness and connector compatibility with the appliance before installing.

Defrost timer that advances the refrigerator's defrost cycle at roughly six-hour intervals to help prevent excessive frost buildup and keep cooling consistent. Replaces a failed timer to restore regular defrost scheduling. What it does:

• Advances the defrost cycle so the heater can melt frost from the evaporator on a timed schedule.
• Helps prevent heavy ice buildup that can reduce airflow and cooling performance.
• Common symptoms of a failing timer: excessive frost or ice accumulation, compressor running constantly, or inconsistent temperatures.
• Works with mechanical defrost systems to alternate between cooling and defrost intervals.

• Disconnect power to the appliance before servicing to avoid electrical shock.
• Handle connectors and wiring carefully; ensure all terminals are fully seated.
• Mounting hardware and connector types can vary by model—retain original fasteners and note wiring positions before removal.

This fountain switch controls the refrigerator dispenser's user-activated circuit so the dispenser responds when the lever or pad is pressed. Replaces a worn or failed dispenser switch to restore normal dispenser control. What it does:

• Acts as the user-activated switch for the water/ice dispenser circuit
• Allows the dispenser to energize the valve or auger motor when pressed
• Commonly replaced when dispenser fails to respond or is intermittent
• Helps stop unexpected dispenser activation due to a stuck switch

• One fountain switch

• Disconnect power to the appliance before beginning any repair
• Access may require removing the dispenser/control panel; handle plastic trim carefully
• Avoid pulling on wires; disconnect connectors by their housings, not the wires

The Inverter Box is an OEM component specifically designed for Whirlpool French door refrigerators. Located inside the refrigerator compartment top behind removable panels, the inverter box houses electronic components that control the compressor motor and refrigeration systems.

Causes of a bad inverter box include failure of internal circuit boards over several years of regulating refrigeration cycles or damage from liquid spills inside the unit.  

Symptoms of a bad inverter box include:

• Failure of the refrigerator section to adequately cool and maintain temperatures
• Erratic fluctuations in cold air dispensing from vents     
• Repeated triggering of defrosting modes unnecessarily 
• Inability to regulate between freezer and refrigerator settings

This Whirlpool replacement part is compatible with Maytag, Jenn-Air, Amana, Magic Chef, and Kenmore side-by-side refrigerators.
 

The Electronic Control Board is an OEM part for Whirlpool refrigerators. It serves as the central hub for managing various functions and settings of the refrigerator, including temperature regulation, defrost cycles, and energy-efficient operations. This critical component ensures that all electronic and mechanical parts are synchronized for optimal performance.

Causes of a bad Electronic Control Board can include power surges, exposure to moisture, or general electronic failures. Such issues can impair the board's ability to send and receive signals correctly, affecting the refrigerator's functionality.

Symptoms of a failing Electronic Control Board include:

• The refrigerator not cooling properly
• Irregular or inconsistent temperatures
• The display panel malfunctioning or displaying incorrect information
• Unusual noises due to relays clicking on and off irregularly

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

This electronic power supply board converts incoming AC power to the low-voltage DC used by the refrigerator's controls and components. Replacing a failed board restores stable power to the UI, fans, lights, and cooling functions.

• Converts line voltage to regulated low-voltage DC for control electronics
• Distributes power to the main control, display, sensors, fans, and valve/relay circuits
• Common signs include a blank or non-responsive control panel, no interior lights or dispenser, intermittent power/clicking, or the unit not running even though the outlet has power
• Failures may follow electrical surges or shorted loads

• Disconnect power at the breaker or unplug before servicing; capacitors may hold a charge
• Use ESD protection and handle the board by its edges
• Photograph/label all connectors; transfer wires one by one and ensure full seating
• Mount securely and inspect for pinched/shorted wires before restoring power

This is the main electronic control board that manages the appliance's functions and user commands. It restores proper electronic control when the original board fails or malfunctions. What it does:

• Interprets commands from the console and controls cycles, timers, and key functions
• Powers and sequences motors, valves, heaters, and other driven components as designed
• Can resolve unresponsive controls, incorrect cycle behavior, or intermittent operation
• May clear display errors or communication faults when the board is the root cause

• (1) main control board assembly

• Disconnect power at the breaker or unplug the appliance before starting any work
• Handle the board by the edges; avoid touching components or connector pins to prevent static damage
• Transfer any brackets, harnesses, or mounting hardware from the old board only if present and required
