Having a Problem? (continued)
Situation | Probable Cause & Solution |
The door opens but won't close:
1.If the opener lights blink, check the safety reversing sensor. See page 22.
2.If the opener lights do not blink and it is a new installation, check the down force. See Adjustment Step 2, page 29. For an existing installation, see below.
Repeat the safety reverse test after the adjustment is complete.
The door reverses for no apparent reason and opener lights don't blink:
1.Is something obstructing the door? Pull the manual release handle. Operate the door manually. If it is unbalanced or binding, call for professional garage door service.
2.Clear any ice or snow from the garage floor area where the door closes.
3.Review the force adjustment procedures on page 29.
4.If door reverses in the fully closed position, decrease the travel limits (page 28).
Repeat the 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.
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 pages 12 and 22.
The opener lights… | don't turn on: |
| Replace the light bulb(s) (100 watts maximum). Use a standard neck garage door opener bulb |
| if regular bulb burns out. |
| don't turn off: |
| Is the Light feature on? Turn it off. |
The opener strains or maximum force is needed to operate door:
The door may be out of balance or the springs are broken. Close the door and use the manual 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 for professional garage door service. Do not increase the force to operate the opener.
The opener motor hums briefly, then won't work:
1.The garage door springs are broken. See above.
2.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.
