Position and Mount the Garage Door Opener

NOTE: For additional mounting options refer to the accessories page.

  1. Close the garage door completely.
  2. Slide the garage door opener onto the end of the torsion bar. If the torsion bar is too long or damaged, you may need to cut the torsion bar.
    Ensure the collar does NOT touch the bearing.
  3. Use a level to position and vertically align the garage door opener. Verify the mounting bracket is located on a solid surface such as wood, concrete or door/flag bracket. If installing on drywall, the mounting bracket MUST be attached to a stud.
  4. When the garage door opener is properly aligned, mark the mounting bracket holes. If necessary, tighten collar screws on the torsion bar to hold garage door opener in place while marking holes. NOTE: The garage door opener does not have to be flush to wall.
  5. Remove the garage door opener from torsion bar. Drill 3/16 inch pilot holes at the marked locations. Drill through metal door rail plates if necessary.
  6. Slide the garage door opener back onto the torsion bar until pilot holes align with bracket.
  7. Tighten the 2 square head set screws on the torsion bar. For a hollow torsion bar, tighten screws 3/4 – 1 full turn after making contact with the bar. For a solid shaft torsion bar, tighten screws 1/4 – no more than 1/2 turn after making contact with the shaft. If installing on a keyed torsion bar, DO NOT tighten the screws into the keyway.
  8. Secure the mounting bracket to the wall and to the garage door opener. Use the 14-10 x 2″ screws to secure the mounting bracket to the wall.

Attach the Emergency Release Rope and Handle

  1. Thread one end of the rope through the hole in the top of the red handle so “NOTICE” reads right side up. Secure with an overhand knot at least 1 inch (2.5 cm) from the end of the rope to prevent slipping.
  2. Thread the other end of the rope through the loop in the emergency release cable.
    Adjust rope length so the handle is no higher than 6 feet (1.83 m) above the floor.
    Secure with an overhand knot.

NOTE: If it is necessary to cut the rope, heat seal the cut end with a match or lighter to prevent unraveling.

Install Power Door Lock

The power door lock is used to prevent the garage door from being manually opened could result in an open door falling rapidly and/or unexpectedly.
• NEVER use emergency release handle unless garage doorway is clear of persons and obstructions. once the door is fully closed.

  1. The power door lock must be mounted within 10 feet (3.05 m)
    of garage door opener with approximately a 3 inch (7.6 cm) distance between the center of a door roller and the hole for the power door lock bolt. If possible, mount on same side as garage door opener. The second roller from the bottom is ideal for most installations.
  2. Ensure rail surface is clean and attach lock template to track.
  3. Drill holes as marked on the template.
  4. Fasten power door lock to the outside of the garage door track with hardware provided.
  5. Run bell wire up wall to garage door opener. Use insulated staples to secure wire in several places. Insert wire through the bottom of the garage door opener.
  6. Plug the connector into the garage door opener.

Attach the Cable Tension Monitor (Required)

NOTE: The cable tension monitor is shipped for left side installation. It is recommended that the cable tension monitor be installed on the same side of the door as the garage door opener. For right side installation, remove the snap-ring holding the roller in place and reassemble it on the opposite side of the cable tension monitor.

  1. Make sure the door cable is approximately 3/4″ (19 mm) from the mounting surface. Door adjustments or shimming may be required to achieve proper depth for the door cable.
  2. Position the cable tension monitor as close to the drum as possible. Make sure cable tension monitor is located over a wood support member and the roller is free from any obstructions.
    NOTE: There must be no obstructions in the installation area that prevent the cable tension monitor from closing completely when slack is detected.
  3. Mark and drill 3/16 inch pilot holes for screws (pilot holes are not required for anchors). NOTE: If the cable tension monitor cannot be mounted into wood with the screws provided, it can be mounted into 1/2 inch (1 cm) or greater drywall using the drywall anchors (2) and the #8 screws (2) provided in the hardware bag.
  4. Attach the cable tension monitor to the wall using the hardware provided. Make sure that the roller is on top of the cable.

The cable tension monitor MUST be connected and properly installed before the garage door opener will move in the down direction.
The cable tension monitor detects ANY slack that may occur in the cables and will reverse the door, eliminating service calls.

  1. Run bell wire to garage door opener. Use insulated staples to secure wire.
  2. Connect bell wire to the green quick-connect terminals on the garage door opener (polarity is not important). NOTE: Cable must have tension through entire door travel. Make sure there is no slack in cable on opposite side of garage door during normal operation. If slack occurs during door travel, adjust cables as required.

Install the Door Control (MyQ® Control Panel)

Install door control within sight of garage door, out of reach of small children at a minimum height of 5 feet (1.5 m) above floors, landings, steps or any other adjacent walking surface, and away from ALL moving parts of door.
For gang box installations it is not necessary to drill holes or install the drywall anchors. Use the existing holes in the gang box.

NOTE: Due to power consumption this door control (Model 888LM) cannot be used in conjunction with another wired door control connected to your garage door opener. If an additional door control is needed, the wireless door control model 885LM can be programmed to the door control (Model 888LM).

  1. Strip 7/16″ (11 mm) of insulation from one end of the wire and separate the wires.
  2. Connect wires to the door control. Make sure the polarity is correct. • Red wire to the RED terminal. • White wire to the WHT terminal.
  3. Mark the location of the bottom mounting hole and drill a 5/32″ (4 mm) hole.
  4. Install the bottom screw, allowing 1/8″ (3 mm) to protrude from the wall.
  5. Position the bottom hole of the door control over the screw and slide down into place.
  6. Lift the push bar up and mark the top hole.
  7. Remove the door control from the wall and drill a 5/32″ (4 mm) hole for the top screw.
  8. Position the bottom hole of the door control over the screw and slide down into place. Attach the top screw.
  9. Run the white and red/white wire from the door control to the garage door opener. Attach the wire to the wall and ceiling with the staples (not applicable for gang box or pre-wired installations). Do not pierce the wire with the staple as this may cause a short or an open circuit.
  10. Strip 7/16″ (11 mm) of insulation from the end of the wire near the garage door opener. Connect bell wire to the quick-connect terminals on the garage door opener: white to white and white/red to red.
  11. Fasten the warning placard to the wall next to the door control.

NOTE: DO NOT connect the power and operate the garage door opener at this time. The door will travel to the full open position but will not return to the close position until the safety reversing sensors are connected and properly aligned.

Install Remote Light

The remote light (garage door opener light) is designed to plug directly into a standard 120V outlet. Select an appropriate location on the ceiling to mount the light within 6 feet (1.83 m) of an electrical outlet so that the cord and light are away from moving parts.

  1. Install the hinge and latch clips. Clips slide in between the metal plate and the plastic housing on each side of the light base.
  2. Install screws into the ceiling leaving 1/8 inch (3 mm) of the thread exposed. NOTE: If installing light on drywall and a ceiling joist cannot be located, use drywall anchors provided. No pilot hole is required for drywall anchors.
  3. Determine the length of power cord needed to reach the nearest outlet. Wind any excess cord around cord retainer on the top side of the light base.
  4. Install the light base by pushing onto the screws and turning the base clockwise to lock the light in place.
  5. Install two Type A19 incandescent or compact fluorescent bulbs (100 watt maximum per bulb, 200 watts total). NOTE: Do not use LED bulbs as they may reduce the range or performance of your remote control(s).
  6. Install the light lens by hooking one end of the lens over the hinge and pressing up on the other end to latch into place.
  7. Plug in the light to outlet. NOTE: Light will not operate until
    the garage door opener is activated. Multiple operators in the same garage may cause interference between lights. Program all lights to one operator to avoid interference.

Install the Protector System®

The safety reversing sensor must be connected and aligned correctly before the garage door will move in the down direction. This is a required safety device and cannot be disabled.


When properly connected and aligned, the safety reversing sensor will detect an obstacle in the path of its electronic beam. The sending sensor (with an amber indicator light) transmits an invisible light beam to the receiving sensor (with a green indicator light).
If an obstruction breaks the light beam while the door is closing, the door will stop and reverse to full open position, and the opener lights will flash 10 times.

The sensors must be installed inside the garage so that the sending and receiving sensors face each other across the door, no more than 6 inches (15 cm) above the floor. Either can be installed on the left or right of the door as long as the sun never shines directly into the receiving sensor lens.

The mounting brackets are designed to clip onto the track of sectional garage doors without additional hardware.

If it is necessary to mount the sensors on the wall, the brackets must be securely fastened to a solid surface such as the wall framing. Extension brackets (see accessories) are available if needed. If installing in masonry construction, add a piece of wood at each location to avoid drilling extra holes in masonry if repositioning is necessary.

The invisible light beam path must be unobstructed. No part of the garage door (door tracks, springs, hinges, rollers or other hardware) may interrupt the beam while the door is closing.

Be sure power to the opener is disconnected. Install and align the brackets so the safety reversing sensors will face each other across the garage door, with the beam no higher than 6″ (15 cm) above the floor. Choose one of the following installations.

OPTION A: Track Installation

1. Slip the curved arms over the rounded edge of each door track, with the curved arms facing the door. Snap into place against the side of the track. It should lie flush, with the lip hugging the back edge of the track, as shown.

If your door track will not support the bracket securely, wall installation is recommended.

OPTION B: Wall Installation

  1. Place the bracket against the wall with curved arms facing the door. Be sure there is enough clearance for the sensor beam to be unobstructed.
  2. If additional depth is needed, an extension bracket (see Accessories) or wood blocks can be used.
  3. Use bracket mounting holes as a template to locate and drill (2) 3/16″ diameter pilot holes on the wall at each side of the door, no higher than 6″ (15 cm) above the floor.
  4. Attach brackets to wall with lag screws (not provided).
