The LiftMaster K-N7GH5043M E-BOX (also referenced as N7GH5043M) is a genuine OEM replacement electronics box used in select LiftMaster commercial operator systems. This factory assembly houses the operator’s control electronics and wiring interfaces, restoring proper control of motor drive functions, limit inputs, and accessory connections in compatible units. It is intended for repairs where the original E-BOX has been damaged or has failed, helping maintain reliable access control performance in commercial and industrial applications such as gates and barrier operators.
As an electronics assembly, the K-N7GH5043M/N7GH5043M provides terminations for safety devices (e.g., photo eyes and edges), access accessories (keypads, card readers, radio receivers), and operator status/control wiring. Installation should be performed with power disconnected and in accordance with the specific operator’s service manual; transferring harnesses and setting configuration options may be required, and limits and accessory inputs may need to be reprogrammed after replacement. Compatibility is model-specific—verify fit using the LiftMaster parts list or the operator’s parts diagram for your exact model and serial range. For UL 325 compliance and safe operation, ensure all monitored safety sensors are correctly connected and tested after the E-BOX is installed.
