When your garage door opener stops working, one of the most frustrating parts of repair or replacement is figuring out the correct replacement circuit board. Since Chamberlain and LiftMaster offer dozens of opener models — and each may require a specific logic board — it’s critical to find the right match. That’s where a Chamberlain LiftMaster Garage Door Opener Circuit Board Compatibility Chart becomes incredibly useful.
This in-depth guide not only includes a detailed compatibility chart, but also explains how circuit boards work, how to identify yours, and how to ensure you choose the correct replacement. Whether you’re a DIY enthusiast or a professional installer, this resource will help you understand everything you need to know about Chamberlain LiftMaster garage door opener circuit board compatibility.
What Is a Garage Door Opener Circuit Board and Why Is Compatibility Important?
The circuit board, often referred to as the logic board, is the brain of your garage door opener. It controls all operational commands such as opening, closing, light activation, safety sensors, and remote control signals. If this board fails, your opener may stop responding, work intermittently, or show signs of electrical issues like flashing lights or clicking sounds.
Why compatibility matters:
- Using an incorrect circuit board can lead to short-circuiting, improper operation, or complete opener failure.
- Not all Chamberlain or LiftMaster models use the same voltage or features.
- Even similar-looking boards might not be interchangeable due to firmware differences.
That’s why the Chamberlain LiftMaster Garage Door Opener Circuit Board Compatibility Chart is an essential tool when replacing a faulty unit.
Signs Your Garage Door Opener Circuit Board Needs Replacement
Before diving into the compatibility chart, it’s helpful to confirm whether your opener’s logic board is indeed the problem. Here are common symptoms:
- Garage door opener does not respond to remote or wall control.
- Light on the opener blinks or doesn’t turn on at all.
- Opener makes clicking sounds but doesn’t operate the motor.
- Safety sensors are functioning, but the opener still doesn’t work.
- Circuit board has visible burn marks, corrosion, or damaged solder joints.
If you’re experiencing these issues, and you’ve ruled out sensors, remotes, and mechanical issues, it’s likely time to replace the circuit board.
How to Identify Your Chamberlain or LiftMaster Opener Model and Circuit Board
Before referencing the compatibility chart, gather the following:
- Garage door opener model number – Usually located on a label on the back or side of the opener.
- Serial number and manufacturing date – Found on the same label.
- Current circuit board part number – Typically printed directly on the circuit board itself, which requires opening the cover.
Once you have these, use the Chamberlain LiftMaster Garage Door Opener Circuit Board Compatibility Chart to find the correct part.

Chamberlain LiftMaster Garage Door Opener Circuit Board Compatibility Chart: Additional Considerations
In addition to part numbers, consider these factors:
- Frequency Matching: Most LiftMaster and Chamberlain openers operate at 315 MHz or 390 MHz. Ensure your board matches your remote control frequency.
- Smart Home Features: If you’re using MyQ, HomeLink, or Wi-Fi integration, ensure your new circuit board supports those features.
- Firmware Versions: Some models use different firmware revisions. Always use a board recommended for your opener’s exact serial number range.
- Security Protocols: Security+ and Security+ 2.0 are not cross-compatible in many cases.
Why LiftMaster and Chamberlain Models Share Circuit Boards
Chamberlain is the parent company of LiftMaster, Craftsman (garage opener line), and even Raynor. This means many models across these brands share components, including logic boards.
This shared architecture makes it easier to find replacements, but also makes it more important to use a Chamberlain LiftMaster Garage Door Opener Circuit Board Compatibility Chart to confirm matches and avoid mistakes.
Preventing Future Circuit Board Failures
Once you’ve installed your replacement logic board, take these steps to help extend its lifespan:
- Surge Protection: Use a surge protector on your opener’s power outlet.
- Keep it Dry: Avoid water leaks or condensation in the garage.
- Regular Maintenance: Keep sensors, remotes, and moving parts clean and functional.
- Avoid Excessive Heat or Cold: Garage temperature swings can degrade electronics over time.
