4. Compatibility

This replacement control board is specifically designed to be compatible with Midea air conditioning units that utilize the following original part numbers:

• Model: CE-KFR26G/BP2N1Y-AE.D01.NP-1
• Circuit PCB Part Number: 17122000016838

Before purchasing and installing, verify that your existing air conditioner's control board matches these specifications to ensure proper fit and function.

5. Installation Guide

Due to the complexity and safety requirements, installation of this control board should only be performed by a qualified HVAC technician. The following steps are general guidelines and not a substitute for professional expertise.

1. Disconnect Power: Ensure the main power supply to the air conditioning unit is completely disconnected at the circuit breaker. Verify with a voltage tester.
2. Access Control Board: Carefully open the air conditioner's outdoor or indoor unit casing to access the existing control board.
3. Document Connections: Before disconnecting any wires, take clear photographs or make detailed diagrams of all existing wire connections to the old control board. Note the position and color of each wire.
4. Remove Old Board: Disconnect all wires and mounting screws securing the old control board. Carefully remove it from the unit.
5. Install New Board: Position the new YRGGWB control board in the same location as the old one. Secure it with the appropriate mounting screws.
6. Connect Wiring: Refer to your documented connections and carefully re-attach all wires to the corresponding terminals on the new control board. Double-check each connection for security and correct placement.
7. Close Unit: Once all connections are verified, carefully close and secure the air conditioner's casing.
8. Restore Power: Restore power to the air conditioning unit at the circuit breaker.
9. Test Functionality: Power on the air conditioner and test all functions (cooling, heating, fan speeds, etc.) to ensure proper operation.

6. Operation

The control board itself does not have user-operable controls. Its function is to process signals from the thermostat and other sensors to manage the air conditioner's components (compressor, fan, valves, etc.). Once installed, the air conditioner will operate as designed, controlled by its standard user interface (e.g., remote control, wall thermostat).

7. Maintenance

The control board itself requires no routine user maintenance. However, to ensure its longevity and the overall health of your air conditioning system:

• Ensure the air conditioning unit is kept clean and free from dust and debris, especially around the control board area.
• Regularly schedule professional maintenance for your entire air conditioning system.
• Protect the unit from extreme moisture or environmental conditions.

8. Troubleshooting

If your air conditioner experiences issues after replacing the control board, consider the following common troubleshooting steps. Always ensure power is disconnected before inspecting internal components.

• Unit Not Powering On:
  • Check the main power supply and circuit breaker.
  • Verify all power connections to the control board are secure.
  • Ensure the thermostat is correctly wired and functioning.
• Incorrect Temperature Control:
  • Inspect temperature sensors connected to the control board for proper placement and connection.
  • Verify thermostat settings.
• Erratic Operation / Malfunctions:
  • Re-check all wiring connections for looseness or incorrect placement.
  • Ensure no foreign objects or debris are interfering with the board or its components.
  • If issues persist, consult a qualified technician.

For complex issues, professional diagnosis is recommended.
