1. Product Overview
The GE WR87X29409 is a genuine Original Equipment Manufacturer (OEM) replacement inverter designed for GE refrigeration appliances. This component is crucial for regulating the power supplied to the compressor, ensuring efficient and consistent cooling performance. It replaces previous models WR55X11099 and WR55X26038.

A yellow caution label is visible on the side, warning against contact with oil. A measuring tape is shown at the bottom, indicating the unit's approximate size.
2. Safety Information
WARNING: Before attempting any installation or maintenance, always disconnect power to the appliance at the circuit breaker or fuse box to prevent electric shock.
- Only qualified technicians should perform installation or repair procedures.
- Wear appropriate personal protective equipment, including safety glasses and gloves.
- Handle electrical components with care.
- Ensure all connections are secure and properly insulated.
- CAUTION: As indicated on the product label, do not allow the inverter's plastic housing to come into contact with oil, as this may cause the plastic to crack and compromise the unit's integrity.
3. Installation Instructions
This inverter is a critical component of your refrigeration system. Professional installation is highly recommended due to the complexity and potential safety risks involved with appliance repair.
- Disconnect Power: Ensure the refrigerator is completely unplugged or the circuit breaker is off before beginning.
- Access the Inverter: Locate the existing inverter, typically found near the compressor at the back of the refrigerator. This may require moving the appliance and removing access panels.
- Document Connections: Before disconnecting any wires, take clear photos or make diagrams of the existing wiring connections to ensure correct reassembly.
- Remove Old Inverter: Carefully disconnect all wiring harnesses and mounting hardware securing the old inverter. Note that some installations may be very tight, requiring careful maneuvering to avoid damaging sealed refrigeration lines.
- Inspect Compressor: While the inverter is removed, it is advisable to check the compressor's terminals for consistent resistance (e.g., 6.2 ohms across all three terminals, as observed in some models).
- Install New Inverter: Mount the new GE WR87X29409 inverter in the same location. Ensure it is securely fastened.
- Connect Wiring: Reconnect all wiring harnesses to the new inverter according to your documentation. Double-check all connections for security.
- Restore Power: Once installation is complete and all panels are resecured, restore power to the appliance.
- Test Operation: Monitor the refrigerator for proper operation, ensuring the compressor starts and the cooling system functions correctly.
Note: The physical appearance of the new inverter may differ slightly from the original part (e.g., color or minor design variations), but it is functionally compatible.
4. Operating Instructions
The GE WR87X29409 Refrigeration Appliance Inverter operates automatically as part of your refrigerator's cooling system. Once installed and power is restored, the inverter will regulate the variable speed compressor to maintain the desired temperature within the refrigerator and freezer compartments. No user intervention is required for its operation.
5. Maintenance
The inverter itself is a sealed unit and does not require routine maintenance. However, proper care of your refrigeration appliance can extend the life of all its components, including the inverter.
- Keep Condenser Coils Clean: Regularly clean the condenser coils (usually located at the back or underneath the refrigerator) to ensure efficient heat dissipation. Dirty coils can cause the compressor and inverter to work harder, potentially leading to premature failure.
- Ensure Proper Ventilation: Maintain adequate clearance around the refrigerator to allow for proper airflow, preventing overheating of components.
- Consider Remote Mounting (Advanced): In some cases, if the original inverter location experiences excessive heat, advanced users or technicians may consider remotely mounting the inverter to a cooler area with extended wiring to improve longevity. This modification should only be performed by experienced professionals.
6. Troubleshooting
If your refrigerator is experiencing issues after inverter replacement, or if you suspect inverter failure, consider the following:
- No Cooling/Compressor Not Starting: This is a primary symptom of inverter failure. Ensure the appliance has power and all connections to the inverter are secure.
- Check Input Voltage: A qualified technician can measure the voltage going into the inverter (typically 3 to 5 volts DC) to confirm the control board is sending power.
- Check Compressor Resistance: Verify the resistance across the three terminals of the compressor. All three readings should be consistent (e.g., 6.2 ohms). Inconsistent readings may indicate a compressor issue rather than an inverter issue.
- Alarm Codes: Consult your refrigerator's service manual for any diagnostic alarm codes that may indicate a specific fault.
If troubleshooting steps do not resolve the issue, it is recommended to contact a certified appliance repair technician.
