B&D Controll-A-Door 4 (CAD4) garage door opener is a popular model in the Australian market. However, some CAD4 units may stop working after a few years, and a common issue is a fault in the built-in radio reception of the unit's PC board. This does not mean the board is completely dead, as adding a stand-alone receiver can restore functionality. Installing a receiver kit CAD4 KIT is a straightforward process: simply hook up the two-wire harness to terminals 1 and 2 at the back of the CAD4 unit. To confirm if your CAD4 has lost reception, you can create a short circuit (a of pulse) by using a piece of wire or long needle pliers beteen  the terminal 1 and 2 and observe if the opener starts functioning again.

Please note the manufacturer has ceased production of the board for B&D CAD4. What is available now is used one which has been tested and works fine.
