Having a Problem? (Continued) 10. The door reverses for no apparent reason and opener lights don't blink: • Is something obstructing the door? Pull the emergency release handle. Operate the door manually. If it is unbalanced or binding, call a trained door systems technician. • Clear any ice or snow from the garage floor area where the door closes. • Review Adjustment Step 2. • If door reverses in the fully closed position, decrease the travel limits (Adjustment Step 1). Repeat safety reverse test after adjustments to force or travel limits. The need for occasional adjustment of the force and limit settings is normal. Weather conditions in particular can affect door travel. 11. The door reverses for no apparent reason and opener lights blink for 5 seconds after reversing: • Check the safety reversing sensor. Remove any obstruction or align the receiving eye. See Installation Step 10. 12. The opener lights don't turn on: • Replace the light bulbs (75 watts maximum). Use a standard neck garage door opener bulb if regular bulb burns out. 14. The opener strains or maximum force is needed to operate door: • The door may be out of balance or the springs may be broken. Close the door and use the emergency release handle to disconnect the trolley. Open and close the door manually. A properly balanced door will stay in any point of travel while being supported entirely by its springs. If it does not, disconnect the opener and call a trained door systems technician. Do not increase the force to operate the opener. 15. The opener motor hums briefly, then won't work: • The garage door springs may be broken. See above. • If the problem occurs on the first operation of the opener, door may be locked. Disable the door lock. Repeat the safety reverse test after the adjustment is complete. 16. The opener won't operate due to power failure: • Use the emergency release handle to disconnect the trolley. The door can be opened and closed manually. When power is restored, press the Door Control push bar and trolley will automatically reconnect (unless trolley is in lockout position). See page 25. • The Outside Quick Release accessory (for use on garages with no service door) disconnects the trolley from outside the garage in case of power failure. 13. The opener lights don't turn off: • Is the Light feature on? Turn it off. 17. The chain droops or sags: • It is normal for the chain to droop slightly in the closed door position. Use the emergency release rope and handle to disconnect the trolley. If the chain returns to the normal height when the trolley is disengaged, and the door reverses on a 2x4 laid flat, no adjustments are needed. (See page 7.) 28
