Frequently Asked Questions - CMXEOCG231 Craftsman

How do I program the travel limits?
Press and hold the Adjustment Button until the UP Button flashes. Press and hold UP until the door reaches the desired open position, then press the Adjustment Button. The DOWN Button will flash. Press and hold DOWN until the door reaches the desired closed position, then press the Adjustment Button. The door will then travel to the programmed positions.
How do I test the safety reversal system?
Place a 1-1/2 inch (3.8 cm) board (or a 2x4 laid flat) on the floor under the garage door. Press the remote control to close the door. The door should stop and reverse when it contacts the board. If it does not, repeat the travel programming and test again. If it still fails, contact a trained door systems technician.
How do I replace the remote control battery?
Use a visor clip or screwdriver blade to pry open the remote case. Insert a new 3V CR2032 coin cell battery with the positive side up (+). Dispose of the old battery properly.
How do I manually open the garage door if the power is out?
Pull down on the emergency release handle so the trolley release arm snaps to the vertical position. The door can then be raised and lowered manually. To reconnect, pull the handle toward the opener until the release arm snaps to the horizontal position; the trolley will re-engage on the next operation.
What should I do if the garage door won't close and the lights flash?
Check the safety reversing sensors: ensure they are aligned, clean, and no obstructions block the beam. Verify sensor wires are not cut or disconnected. If the LEDs on both sensors are not glowing steadily, realign them. Also check for any short or reversed wiring.
How do I install the safety reversing sensors?
Mount the sensors on either side of the garage door, no more than 6 inches (15 cm) above the floor. Ensure the lenses face each other and the beam is unobstructed. Connect the sensor wires to the garage door opener terminals: white to white, and white/black to grey. Align the sensors and tighten wing nuts.
What type of light bulb can I use in the opener?
Use only A19 incandescent bulbs up to 100W or compact fluorescent bulbs up to 26W (100W equivalent). Do not use halogen, short neck, specialty, or LED bulbs as they may overheat or affect remote control performance.
How do I erase all remote controls and keyless entries from memory?
Press and hold the LEARN button on the garage door opener until the LED goes out (about 6 seconds). All remote control and keyless entry codes are erased. To also erase all devices (including myQ accessories), press and hold the LEARN button again until the LED goes out.
Can this opener be installed on a one-piece garage door?
Yes, but only if not using unattended close features. One-piece doors may require additional reinforcement and different header bracket height (8 inches above the highest point of travel). Follow the specific instructions for one-piece doors in the manual.
How do I adjust the chain tension?
First, pull the emergency release to disconnect the trolley. On the trolley threaded shaft, spin the inner nut and lock washer away from the trolley, then turn the outer nut to tighten or loosen the chain. When the chain is approximately 1/4 inch (6 mm) above the base of the rail at its midpoint, retighten the inner nut to secure.

IMPORTANT INFORMATION ABOUT THE SAFETY REVERSING SENSORS

The safety reversing sensors must be connected and aligned

garage door opener will move in the down direction.

The sending sensor (with an amber LED) transmits an invisible receiving sensor (with a green LED). If an obstruction breaks the door is closing, the door will stop and reverse to the 1 garage door opener lights will flash 10 times.

NOTE: For energy efficiency the garage door opener will enter sleep mode when the door is fully closed. The sleep mode shuts the garage door opener down until activated. The sleep mode is sequenced with the garage door opener lights; as the lights turn off, the sensor LEDs will turn off and whenever the garage door opener lights turn on, the sensor LEDs will light. The garage door opener will not go into the sleep mode until the garage door opener has completed 5 cycles upon power up.

When installing the safety reversing sensors check the following:

  • Sensors are installed inside the garage, one on either side of the door.
  • Sensors are facing each other with the lenses aligned and the receiving sensor lens does not receive direct sunlight.
  • Sensors are no more than 6 inches (15 cm) above the floor and the light beam is unobstructed.

AUTOMATIC GARAGE DOOR OPENER SAFETY & MAINTENANCE GUIDE

GARAGE DOOR OPENER SAFETY — AN AUTOMATIC DECISION

A garage door is the largest moving object in the home. An improperly adjusted garage door and opener can exert deadly force when the door closes – which could lead to entrapment of children or adults and subsequent injury or death.

Proper installation, operation, maintenance, and testing of the garage door and automatic opener are necessary to provide a safe, trouble-free system. Careless operation or allowing children to play with or use garage door opener controls are also dangerous situations that can lead to tragic results. A few simple precautions can protect your family and friends from potential harm. Please review the safety and maintenance tips in this guide carefully and keep it for reference. Check the operation of your garage door and opener to ensure they function in a safe and trouble-free manner. Be sure to read all Important Safety Information found in your garage door opener's manual as it provides more details and safety considerations than can be supplied with this guide.
