WG04A00766 - Genuine OEM GE Refrigerator Invertor Board Kit With Jumpers

WG04A00766 – Genuine OEM GE Refrigerator Inverter Board Kit With Jumpers

The WG04A00766 is a Genuine OEM GE refrigerator electronic control component designed for select GE refrigeration systems that use variable-speed compressor technology. This inverter board kit is compressor-mounted and works with included jumpers to regulate compressor speed, cooling cycles, and overall refrigeration performance. It is commonly used across compatible GE, Monogram, Café, Profile, Hotpoint, Moffat, Kenmore, Westinghouse, and related GE-manufactured refrigerators.

If your refrigerator is no longer cooling properly, the compressor will not start, or your unit cycles erratically despite having power, replacing a failed inverter board often restores normal cooling performance.

Available from Appliance Kingdom with fast Canada-wide shipping for homeowners, landlords, and professional appliance repair technicians.

What Does the WG04A00766 Inverter Board Do?

The inverter board controls the refrigerator’s variable-speed compressor operation by converting and regulating electrical signals between the main control board and compressor.

This allows your refrigerator to:

• Adjust compressor speed based on cooling demand

• Maintain precise internal temperatures

• Improve energy efficiency

• Reduce compressor wear

• Deliver quieter and more consistent cooling performance

Because this board directly controls compressor performance, OEM precision is critical. A non-genuine or incorrectly matched inverter board can cause communication errors, startup failures, cooling loss, or compressor damage.

Common Symptoms of a Failed Refrigerator Inverter Board

A defective WG04A00766 inverter board may cause:

• Refrigerator not cooling

• Freezer warming unexpectedly

• Compressor not starting

• Compressor clicks but does not run

• Intermittent cooling loss

• Refrigerator powers on but internal temperatures rise

• Unit repeatedly cycles on and off

• Unusual humming or startup attempts without cooling

Replacing the inverter board often resolves these issues when the compressor itself remains functional. However, professional diagnosis is recommended to confirm the compressor and sealed system are operating correctly before replacement. Community repair discussions frequently note that inverter symptoms can sometimes overlap with sealed-system faults or compressor failures.

Compatibility Guidance

The WG04A00766 is designed for GE refrigerator applications using inverter-driven compressor systems.

Before ordering:

• Verify your refrigerator’s complete model number

• Confirm your appliance uses an inverter compressor system

• Match the installed inverter board part number if accessible

Model numbers are typically located inside the refrigerator compartment on the wall or frame.

If you need assistance confirming compatibility, the support team at Appliance Kingdom can help verify fitment before purchase.

Installation Overview

Replacing the WG04A00766 inverter board is generally considered an advanced refrigerator repair.

Installation usually involves:

• Disconnecting appliance power

• Accessing rear compressor compartment

• Removing the failed inverter board

• Installing the replacement board and jumpers

• Reconnecting wiring harnesses securely

• Restoring power and verifying compressor startup

Because this is an electrical compressor-control component, professional installation is strongly recommended unless you have appliance electrical repair experience.

Important: Many suppliers do not accept returns on installed electrical parts, so compatibility verification before ordering is essential.
