LiftMaster K001A5747-2 390 MHz Receiver Module for LA400 Technical Details
The LiftMaster K001A5747-2 is a 390 MHz receiver module used in select LiftMaster LA400 swing gate operator control box service applications. The receiver module is the radio section that receives signals from compatible transmitters or wireless access devices.
Frequency matters on this part. K001A5747-2 is commonly listed as the 390 MHz module, while K001A5747 is commonly associated with the 315 MHz module. Those modules should not be treated as interchangeable without confirming the operator generation, remotes, and site programming.
Before replacing the receiver, check the antenna, coax connection, remote battery, remote model, and nearby radio interference. Weak reception is not always caused by the receiver module itself.

Technician Note
If a site has poor range, check antenna placement and coax condition before replacing the receiver. A damaged antenna or low remote battery can mimic receiver failure.
Before Ordering
- Confirm the operator is a compatible LA400 control box application
- Confirm the site uses 390 MHz compatible remotes or keypads
- Do not confuse this with K001A5747 315 MHz
- Inspect the antenna and wiring before replacing the module
- Plan to reprogram remotes or access devices as required after service
Professional Advisory
Gate radio controls should not be modified in a way that bypasses entrapment protection, access control logic, or UL 325 safety requirements. Use a qualified gate technician for uncertain radio or control-box repairs.
