How do I get the trolley off the stop bolt or stop tab?

The trolley can become lodged against the stop bolt/tab because the door has either opened or closed too far. The garage door opener motor willhum when attempting to open or close the door but is unable to travel due to being lodged against the bolt/tab. Typically this is caused by a

misadjustment.

Stop Bolt

To remove the trolley from the stop bolt, follow the steps below:

1. First visually ve rify that the trolley is against the stop bolt.

2. Make sure the garage doorway is clear of persons or obstructions.

3. Release the door from the garage door opener by pulling the Emergency Release Handle.4. Manually bring the door to the closed position.

5. Loosen the chain or belt by adjusting the outer nut   4 to 5 turns. This relieves the tension.

6. Run the motor unit from the remote control or door control. The trolley should travel towards the door and stop. If the trolley re-engages

with the door, pull the Emergency Release Handle to disengage.

7. Decrease the UP travel. Depending on the type of garage door opener you have, there are two methods for adjusting the travel:

Turn the UP travel adjustment screw 2 full turns away from the arrow,

OR 

  Use the buttons to reprogram the UP travel. (See your users manual for complete programming steps)

8. Re-tighten the outer nut so the chain or belt is 1/2 inch (T-Rail) or 1/4 inch (Square Rail) above the base of the rail. (When the door is

reconnected and closed, the chain will sag. This is normal.)

9. If the trolley does not move away from the bolt, repeat the steps above.

In rare instances this issue may occur due to a part failure such as the logic board.

Stop Tab

To remove the trolley from the stop tab, follow the steps below:

1. First visually ve rify that the trolley is against the stop tab.

2. Make sure the garage doorway is clear of persons or obstructions.

6. Decrease the DOWN travel. Depending on the type of garage door opener you have, there are two methods for adjusting the travel:

Turn the DOWN travel adjustment screw 2 full turns away from the arrow,

OR 

  Use the buttons to reprogram the UP travel. (See your users manual for complete programming steps)

In rare instances this issue may occur due to a part failure such as the logic board.

After ANY adjustments are made, the safety reversal system MUST be tested. The door MUST reverse on contact with 1-1/2" high (3.8 cm) object

(or 2X4 laid flat) on the floor.
