3. Installation (Setup)
Follow these steps carefully to replace your refrigerator's control board. Ensure all safety precautions are observed.
- Turn Off Power: Before beginning any work, ensure the refrigerator is completely disconnected from all power sources (AC and DC). This includes unplugging from shore power, turning off the inverter, and disconnecting battery power if applicable.
Safety Warning: Failure to disconnect power can result in electric shock or damage to the appliance.
- Remove Old Board: Carefully locate the existing control circuit board. Disconnect all wires and connectors from the old board, noting their positions for reinstallation. Gently detach the old board from its mounting.

- Install New Board: Position the new Aepiraza Micro P-711 control board in the same location as the old one. Reconnect all wires and connectors to the new board, ensuring they are securely attached to their correct terminals. The board is designed for easy installation and integrates seamlessly with both original and updated wiring configurations.
Note: You may need to make a short ground wire if your previous setup did not utilize the additional ground terminal on this board.
- Test Operation: Once the new board is securely installed and all connections are made, reconnect the refrigerator to its power sources. Turn on the refrigerator and test its functions to ensure the new board is operating correctly and the refrigerator is cooling as expected.
4. Operation
The Aepiraza Micro P-711 control board functions automatically once installed, managing the refrigerator's core operations. Users primarily interact with the refrigerator's existing controls (e.g., temperature dial, mode selection) which are then managed by this board.
4.1 Temperature Control
The board features a built-in temperature adjustment capability. Use your refrigerator's standard temperature controls to set the desired cooling level. The Micro P-711 will regulate the power and cooling cycles to maintain the set temperature.
4.2 Automatic Mode Selection
The board automatically detects the type of "eyebrow" (control panel) in your refrigerator and adapts its operation accordingly, ensuring optimal performance for both 2-way (AC/Gas) and 3-way (AC/DC/Gas) systems.
5. Maintenance
The Aepiraza Micro P-711 control board is designed for long-lasting, reliable performance with minimal maintenance required. However, periodic checks can help ensure continued optimal operation.
- Visual Inspection: Periodically inspect the board and its connections for any signs of loose wires, corrosion, or physical damage. Ensure the protective casing is intact.
- Fuse Check: The board includes fuse protection for 120 VAC circuits, 12 VDC power, and DC elements. If the refrigerator experiences power issues, check the relevant fuses on the board. Refer to the refrigerator's original manual for fuse locations and ratings if needed.
- Cleanliness: Keep the area around the control board clean and free from dust or debris, which can impede proper heat dissipation.
