LiftMaster 02-108 Three-Button Indoor Flush-Mount Station — Open / Close / Stop

The LiftMaster 02-108 is the three-button, indoor flush-mount control station identified with OPEN, CLOSE and STOP functions. It must match the operator’s approved control circuit and the site’s mounting arrangement. It is separate from a two-button constant-pressure station, a key switch and an outdoor weather-rated station. The number of buttons does not by itself establish compatibility, operating mode or every required stopping and interlock function. Select the replacement by the complete part number and the installed equipment configuration. A similar photograph or a shared LiftMaster brand name does not establish interchangeability. Confirm the applicable service drawing before ordering so the repair addresses the correct component and its related mounting, connection and operating requirements.

Compatibility — Models, Versions and Exclusions

Identify the Assembly and Plan the Repair

Confirm the operator control mode and mounting provisions before opening a wall or ordering a replacement. A station that looks similar can use a different enclosure, contact arrangement or wiring layout. Identify the existing controls and obtain the exact station and operator installation information.

Place controls where the user can observe the door or gate and remain clear of moving parts, as required by the equipment instructions. Preserve the STOP circuit and all required interlocks and protection devices. A three-button station is not an emergency-egress design or a substitute for entrapment protection.

An electrical symptom does not identify the failed component by itself. Have qualified service personnel inspect the supply, wiring, connections and equipment condition before replacing parts. Record existing labels and terminal references with power safely isolated. A replacement should restore the documented circuit arrangement; it should not be used to change operating voltage, defeat a protective function or compensate for a mechanical load that the equipment cannot safely move.

Compare the delivered item with the approved service reference before installation. The installer must obtain the equipment-specific wiring, mounting and commissioning instructions rather than infer them from the appearance of the part. Keep conductors clear of moving components and reinstall the intended covers. After the repair, check the original complaint and the equipment’s required operating and safety functions; a successful power-up alone is not a complete service test.

Specifications and Product Identification

Before Ordering

• Confirm 02-108 and indoor flush mounting.
• Match the operator’s approved control circuit.
• Check the wall/back-box and wiring requirements.

Package Contents and Separate Requirements

This offer identifies the control station. Operator, field wiring, conduit, wall preparation and separate safety devices are not included unless expressly bundled. Confirm the current enclosure, back-box and mounting-hardware inventory before ordering. A station-only purchase does not provide a complete control-system conversion.

Safety Warnings — Read Before Installation or Service

• WARNING: Electrical service can expose hazardous voltage and moving equipment. Use qualified service personnel and electrical personnel where required.
• Disconnect every applicable mains, battery and auxiliary supply before work. Follow the equipment instructions for stored energy and safe isolation.
• Preserve the STOP circuit and required interlocks. Test OPEN, CLOSE and STOP under the approved operator wiring mode before normal use.
• Restore covers and wiring protection, then complete the model-specific functional and safety checks before returning the installation to normal use.
