Inverter Split AC Outdoor PCB Board Suitable for Daikin Split AC 1 Ton, 1.5 Ton & 1.8 Ton Inverter AC Outdoor Unit Control PCB Compressor, Fan & Inverter Control Board PCB

Step 1 – Switch Off the Power Turn OFF the AC and disconnect the main electrical power supply. Wait for the inverter circuit's capacitors to discharge before beginning work. Step 2 – Open the Outdoor Unit Remove the outdoor unit electrical/control box cover to access the existing PCB. Step 3 – Photograph Existing Connections Before removing the old PCB, take clear photographs of all connectors and wiring. This helps during reinstallation. Step 4 – Remove the Existing PCB Disconnect the connectors carefully and remove the mounting screws/clips holding the existing PCB. Step 5 – Compare the New PCB Check the new PCB against the original PCB. Confirm the model number, PCB part number, connectors, terminal positions and component configuration. Step 6 – Install the New PCB Mount the replacement PCB securely in the original position using the appropriate mounting points. Step 7 – Connect All Wiring Reconnect all connectors according to the original wiring arrangement and PCB markings. Do not connect wires based only on colour. Step 8 – Inspect the Installation Check for loose connectors, incorrect connections, damaged wires or short circuits. Step 9 – Test the AC Restore power and test the AC. Check compressor operation, outdoor fan operation, communication, cooling performance and error codes. Important: Inverter AC outdoor PCBs contain high-voltage circuits and charged capacitors. Installation should be carried out by a qualified AC technician. Incorrect wiring or installation can damage the PCB, compressor, fan motor or other components.
