6. Door reverses for no apparent reason and opener light blinks for 5 seconds after reversing:
Check The Protector System™ (if you have installed this accessory). If the light is blinking, correct alignment.
Note:
Continuously holding down the door control button will allow the door to close if the protector system is not properly aligned. The transmitter will
not close the door. The opener lights will blink.
7. Opener noise is disturbing in living quarters of home:
If operational noise is a problem because of proximity of the opener to the living quarters, Vibration Isolator Kit 41A3263 can be installed. This kit was
designed to reduce the "sounding board effect" and is easy to install.
8. The garage door opens and closes by itself:
• Delete all remote controls and reprogram.
• Make sure remote push button is not stuck "on".
• Disconnect all push buttons or key switches attached and wait one day.
9. Door stops but doesn't close completely:
Review Limit Adjustment section.
Repeat safety reverse test after any adjustment of door arm length, close force or down limit.
10. Door opens but won't close:
• Check The Protector System™ (if you have installed this accessory). If the light is blinking, correct alignment.
• If opener light does not blink and it is a new installation, check the down force.
Repeat the safety reverse test after the adjustment is complete.
11. Opener light does not turn on:
Replace light bulb (40 Watts maximum). Replace burned out bulbs with rough service light bulbs.
12. Opener light does not turn off:
There may be a defective earth at the ceiling or wall receptacle. The unit must be earthed.
13. Opener strains or reversed during opening:
Door may be unbalanced or springs are broken. Close door and use manual release rope and handle to disconnect trolley. Open and close door man-
ually. A properly balanced door will stay in any point of travel while being supported entirely by its springs. If it does not, call for professional garage
door service to correct the problem. Do not change force settings.
14. Opener motor hums briefly, then won't work:
• Garage door springs are broken. SEE ABOVE.
• If problem occurs on first operation of opener, door is locked. Disable door lock. If chain was removed and reinstalled, the motor may be out of
phase. Remove chain; cycle motor to down position. Observe drive sprocket. When it turns in clockwise direction and stops in down position, re-
install chain.
Repeat safety reverse test after adjustment is complete.
15. Opener won't activate due to power failure:
• Pull manual release rope and handle down and back to disconnect trolley. Door can be opened and closed manually. When the power is restored,
pull the manual release handle straight down. The next time the opener is activated, the trolley will reconnect.
• The Outside Quick Release accessory (if fitted) disconnects the trolley from outside the garage in case of power failure.
