LiftMaster 030DCT Security+ 3.0 Receiver Logic Board Service Kit
LiftMaster 030DCT Security+ 3.0 Receiver Logic Board Service Kit
The LiftMaster 030DCT is a receiver logic-board service kit for documented Security+ 3.0 garage-door opener configurations. Manufacturer parts information identifies this board for the 6690L, 6580L and 4690L models. Match the exact opener, installed board and service instructions before ordering; a shared brand or similar board shape is not enough. The kit repairs the specified control assembly and does not turn an older opener into a new model or automatically add the camera, lighting, battery or accessory capabilities of a different machine.
Compatibility — Models, Versions and Exclusions
| Model or selection point | Compatibility requirement |
|---|---|
| 6690L | Manufacturer parts information identifies 030DCT; verify installed revision. |
| 6580L | Match the exact opener and service reference. |
| 4690L | Match the model-specific repair information. |
| L993S remote | A separately available Security+ 3.0 transmitter for supported models. |
| Older Security+ / Security+ 2.0 boards | No generic upgrade or interchangeable board fit established. |
Identify the Board and Diagnose the Complete Opener
Record the opener model and serial information and photograph the existing board label and connectors before ordering. Symptoms such as a nonresponsive opener can also involve power, wiring, a wall control, motor or travel feedback. Have the fault diagnosed instead of replacing a board merely because a remote no longer works. The full model is more useful than the color or exterior shape of the motor housing.
After fitting the specified board, follow the supplied instructions for restoring settings and programming authorized accessories. Existing remote permissions and travel settings should not be assumed to carry over. Check the operation of the door, sensors and reversal system before routine use. Any connected app or camera functions must be restored through the instructions for the actual opener; the board listing does not promise a separate camera or account service.

Package Contents and Separate Requirements
This offer identifies the 030DCT receiver logic-board service kit. Confirm the current package for board-specific hardware and installation instructions. A complete opener, motor, belt or chain, rail, camera, light assembly, battery, wall control and remote transmitter are not promised as included. The replacement board does not supply every feature-bearing component in the opener housing; identify any additional failed part by its own service number.
Safety Warnings — Read Before Installation or Service
- WARNING: Disconnect opener power and any battery backup before opening the housing or replacing electronics. Use qualified garage-door service personnel.
- Handle the board using the manufacturer precautions and preserve the specified connections. Do not adapt a board from a different model or short terminals to bypass protection.
- A door with damaged springs or counterbalance hardware can move unexpectedly. Have those faults repaired independently before operating the opener.
- Complete the required travel, photo-eye and safety-reversal tests after installation. Keep people and objects clear during controlled testing.
