Residential Jackshaft Opener Door Won't Close

Follow the symptoms and reasonings below in order to resolve why your Residential Jackshaft Opener (RJO) is not opening your garage door.

The door is not engaged - Manually Released

If you attempt to open and close the garage door and the door does not move, pull down on the red release handle to engage the door. Confirm that the door is engaged by attempting to open or close the door manually.

Safety Reversing Sensors may be misaligned or malfunctioning

Note: Any garage door opener or replacement logic board manufactured after February 2022, will no longer have this feature.

The safety reversing sensors must be installed and aligned correctly before the garage door opener will move in the down direction. When the light beam is obstructed or the safety reversing sensors are misaligned, the garage door will reverse while closing and the garage door opener lights will flash ten times. The LEDs on the safety reversing sensors glow steadily when they are aligned and wired correctly. If the safety reversing sensors are blocked or misaligned, the garage door opener will not close the door.

1. Check for an obstruction that may be blocking the sensors. If there is an obstruction, remove it
2. If the green LED on the receiving sensor is flickering or off, you will need to try to align it. If the orange LED is off, check the connection at the operator, check staples for shorts, and/or replace wiring or sensors if necessary.
3. To align the sensor, loosen the wing nut and adjust the position of the sensor until the green LED glows steadily. Then tighten the wing nut
4. If your safety reversing sensors are causing the door to stay open, a diagnostic code will be displayed on the unit along with the work light flashing 10 times

NOTE: If your opener is in Force or Travel Learn Mode your LED will not display any of these diagnostic codes.

• The remote work light would also blink 10 times when attempting to close the door. If the light is not programmed to the opener, try holding the push button on the door control panel to override the sensors and see How to test or troubleshoot the safety reversing sensors to continue troubleshooting.

Cable Tension Monitor (CTM) is activating during operation

NOTE: Two CTM's can be installed on Wi-Fi RJO models. If one is defective or needs to be removed, both CTM's must be removed, cycle power to the unit 2 times, then reinstall the working CTM.

Look at the cable tension monitor on wall mounted garage door openers. The CABLE TENSION MONITOR detects slack in the CABLE and will reverse the door, eliminating service calls for unspoiled CABLE WIRE. The CABLE TENSION MONITOR must be properly installed before the garage door opener will move in the down direction.

1. To identify if your cable tension monitor is now allowing the garage door to close, let us look at the diagnostic codes on the operator
2. Lift up the front cover on the operator, on units with a single LED, if the LED blinks 9 times, or units with UP and DOWN arrows, the LED is blinking the UP arrow 3 times, then DOWN arrow 5 times, the cable tension monitor is not allowing the door to close
3. If the diagnostic codes do not indicating an error with the cable tension monitor, click the link to watch a video on how to perform routine maintenance on your garage door. Otherwise, you may continue to watch this video and the link to the maintenance video will be promoted after the proper installation requirements for the cable tension monitor
4. In order to function properly, the door cable needs to be approximately three quarters of an inch from the mounting surface for the CABLE TENSION MONITOR. If the cable depth is too large, the CABLE TENSION monitor may not react quickly enough to prevent thrown cables. If the cable depth is too small, the CABLE TENSION monitor may cause nuisance reversals. Shimming and/or door adjustments may be needed to achieve the proper cable depth
5. When mounting the monitor be sure to:
   • ​Position it between two and six inches from the DRUM,
   • mount over a wood support,
   • or,
   • Use wall anchors when mounting to drywall
   • Make sure no obstructions will prevent the ROLLER from closing completely

• To troubleshoot the cable tension monitor see article: Residential Jackshaft Opener: The RJO will NOT close the garage door and diagnostic flashes 9 times, or 3 UP and 5 Down.
• For additional information about the cable tension monitor see the link below.

Door weight will not allow force settings to program

1. The safety and reliability of your door and opener system is also dependent on ensuring its proper operation with this monthly checks:
   • Check the balance of your garage door
   • Check how well your garage door moves up and down
2. Start by disconnecting the opener from the door by pulling the emergency release
3. Check to see if the door is balanced by raising the door three to four feet off the ground. Let go of the door. It should stay in place, supported by the door springs. A door that moves a few inches up or down is acceptable
4. Raise and lower the door. It should move smoothly and freely, without any binding or sticking
5. If the door doesn’t move freely, lubricate the door rollers, bearings, and hinges with White Lithium Grease. Do NOT grease the door tracks

• If the door sticks or binds, contact a trained door systems technician to service the garage door
• Never try to loosen, move or adjust garage door, door springs, cables, pulleys, brackets or their hardware. Door rollers, bearings and hinges can benefit from being lubricated once a year. Use a small amount of white lithium based lubricant
• Use regular candle wax to lubricate the area where the garage door comes into contact with the frame of the house. This will help the door slide more easily when opening and closing
• Finally, lubricate the garage door opener rail every three to four years. First, use a clean rag to wipe away any existing lubricant from the center rail. Then apply a thin layer of white lithium based lubricant to a rag and use the rag to lubricate the rail

How do I program the Sec+2.0 travel and force limits using the UP and DOWN arrows?. Or, the door may need pusher springs to help get the door started down. Pusher springs also help keep resistance on the cable during the closing of the door.

• For more information about pusher springs see the link below.
  Residential Jackshaft Opener: How do I know if I need pusher springs?

Notes

• The RJO will have issues with closing the door if the Which door track radius is less than 12" inches or more than 32" inches.
• After any adjustments are made, the safety reversal system must be tested. The door must reverse on contact with 2X4 laid flat on the floor or a 1-1/2" high (3.8 cm) object.
