The LiftMaster K-T5011M E-BOX is the factory electronic control box assembly engineered specifically for the LiftMaster T5011M commercial trolley operator. As an OEM replacement part, this E-BOX houses the operator’s primary controls and electronics, restoring reliable function when the original control enclosure is damaged or fails. It is designed to maintain proper integration with LiftMaster safety and access accessories used with the T5011M, such as monitored photo-eyes, wall controls, radio receivers, and keypads, helping ensure dependable operation on commercial overhead sectional doors.
Intended for use only with the LiftMaster T5011M model, this is not a universal control box and should be matched to the operator identification label before ordering. Installation should be performed by a qualified door professional with power disconnected, following the T5011M service manual for wiring connections, setup, and testing. After replacement, limit settings and entrapment protection must be verified, and accessories like remotes may require reprogramming. Proper installation and testing help maintain compliance with UL 325 and local safety codes in commercial and industrial applications.
