Liftmaster CB124EV, CB SWING 24V EVO
The LiftMaster CB124EV is a 24V EVO control board for select swing, wing, or leaf gate automation systems. It manages motor control, accessory inputs, safety devices, limit or travel functions, and programmed gate behavior for compatible low-voltage operators. On these systems, the control board is not just a switching device; it is the logic platform that coordinates safe and consistent gate movement.
CB124EV is a specific EVO board family and should not be mixed up with CB124, CB1-120, CB2, or CB2-120 boards. It is commonly referenced with the related number 41APEC-0010EV and with external e-box control installations for 24V leaf gate drives. When replacing this board, match the exact board marking, terminal layout, control box, transformer, and accessory wiring. Incorrect substitution can create travel, accessory, or safety-monitoring problems.
Common Replacement Reasons
- 24V EVO swing gate system does not respond to commands.
- Board will not learn or retain programming after power checks.
- Safety or accessory inputs behave incorrectly after wiring is verified.
- Original EVO board has water damage, burned components, or terminal damage.
Compatible With
Common Compatible Applications
- Select LiftMaster/Chamberlain 24V wing gate or leaf gate drive systems using CB124EV.
- CB124EV external e-box control applications for 24V swing gate operators.
- Systems where the original board or manual references CB124EV or 41APEC-0010EV.
Additional Model Families to Verify
- LiftMaster European-style 24V swing gate drives.
- Chamberlain/LiftMaster EVO gate control panel installations.
- 24V leaf gate systems with matching motor, transformer, receiver, and safety terminals.
Important Compatibility Notes
Confirm the exact board marking, terminal labels, motor type, supply voltage, and safety-device setup. CB124EV is not a drop-in replacement for every CB124 or LiftMaster swing gate board.

Technician Note
During replacement, document each terminal before moving wires. EVO boards may have specific programming, travel, safety, and accessory setup steps that must be completed before returning the gate to service.
Before Ordering Checklist
- Confirm the original board label says CB124EV or 41APEC-0010EV.
- Verify the system uses 24V swing/leaf gate drives.
- Compare terminal layout and control-box style.
- Confirm accessories and safety devices are compatible with the EVO board.
- Complete programming and safety testing after installation.
Professional Advisory
Gate control-board replacement should be completed with the operator manual available. If the gate moves unexpectedly, fails safety tests, or has unknown wiring, stop and use a qualified gate technician.
Product Questions & Answers
What is CB124EV used for?
CB124EV is used as a 24V EVO control board for select LiftMaster/Chamberlain swing, wing, or leaf gate systems.
Is CB124EV the same as 41APEC-0010EV?
41APEC-0010EV is commonly associated as a related board/manual reference for the CB124EV control platform.
Can I replace a CB124 with CB124EV?
Do not assume that. CB124 and CB124EV are different board families and must be verified by the operator manual and parts diagram.
Does this board control safety devices?
Yes. It interacts with the safety/accessory inputs on compatible systems, so all required safety devices must be connected and tested.
Why does terminal layout matter?
A different terminal layout can indicate a different board generation or operator platform, and incorrect wiring can damage the board or create unsafe gate movement.
