LiftMaster K001A5747 Receiver Module Overview
The LiftMaster K001A5747 is a genuine replacement 315MHz receiver module for select LiftMaster LA400 linear actuator swing gate operators. In the control box, this module receives the radio signal from compatible remotes and passes the command into the operator control system. It is a small but important part of the access-control side of the gate, especially on LA400 installations where the operator runs properly from hardwired inputs but has weak, intermittent, or failed remote response.
Correct frequency matching is the main issue with this part. LA400 operators can be found with different receiver modules depending on age and configuration, including 315MHz and 390MHz versions. A 315MHz module is not a direct substitute for a 390MHz module, and it will not make older or newer remote families cross-compatible by itself. Before replacing the module, inspect the existing board number, remote frequency, antenna lead, and LA400 electrical box parts diagram. If the operator has water damage, lightning damage, or failed control-board inputs, the receiver module may not be the only part involved.
Compatible With
This receiver module is most strongly associated with the following applications when the installed operator uses the matching 315MHz receiver setup:
- LiftMaster LA400 swing gate operators with a 315MHz receiver module
- Select LA400 electrical box repair applications using receiver module K001A5747
- Commonly referenced with LiftMaster LA400 linear actuator control boxes
- May be referenced for some LA500-related 315MHz swing gate receiver applications by supplier listings, but verify by parts diagram before ordering
- Compatible remote family depends on the installed 315MHz Security+ receiver system and programmed transmitter type

Technician Note
If the gate works from the push button or hardwired input but not from remotes, check the antenna wire, remote batteries, programming, and receiver frequency before replacing this module. A failed receiver module can look like a remote problem, but a wrong-frequency replacement will create the same symptom.
Before Ordering
- Match the original receiver module number to K001A5747
- Confirm the operator is an LA400 or listed LA400 electrical box application
- Confirm the system uses 315MHz remotes, not 390MHz or Security+ 2.0 yellow learn button accessories
- Inspect the antenna lead and control box for corrosion or water intrusion
- Disconnect power before servicing the control box and use a qualified gate technician when needed
Professional Advisory
Receiver and control-board work should be handled with the operator powered down. Do not bypass safety devices or modify the radio circuit to force compatibility with the wrong remote family.
Product Questions and Answers
Is K001A5747 the 315MHz or 390MHz receiver module?
K001A5747 is the 315MHz receiver module. The 390MHz version is commonly listed as K001A5747-2, so the two should not be mixed.
Does this fit every LiftMaster LA400 operator?
It fits select LA400 applications that use the matching 315MHz receiver module. LA400 operators with a different receiver frequency or control box generation need the correct module for that setup.
Will this receiver module fix weak remote range?
It may help if the module is failing, but weak range can also come from a damaged antenna wire, interference, low remote batteries, or a poor receiver location.
Can I use my 390MHz remotes with this 315MHz module?
No. The receiver module and remotes must be on the same supported radio frequency and technology.
Should remotes be reprogrammed after replacing the module?
Yes, in most cases remotes need to be programmed to the replacement receiver module after installation.
