Having a Problem? 1. The opener doesn't operate from either the Door Control or the remote control: • Does the opener have electric power? Plug a lamp into the outlet. If it doesn't light, check the fuse box or the circuit breaker. (Some outlets are controlled by a wall switch.) • Have you disabled all door locks? Review installation instruction warnings on page 7. • Is there a build-up of ice or snow under the door? The door may be frozen to the ground. Remove any restriction. • The garage door spring may be broken. Have it replaced. • Repeated operation may have tripped the overload protector in the motor. Wait 15 minutes and try again. 5. 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, the Vibration Isolator Kit 89LM can be installed. This kit was designed to minimize vibration to the house and is easy to install. 6. The garage door opens and closes by itself: • Be sure that all remote control push buttons are off. • Remove the bell wire from the door control terminals and operate from the remote only. If this solves the problem, the door control is faulty (replace), or there is an intermittent short on the wire between the door control and the motor unit. • Clear memory and re-program all remote controls. 2. Opener operates from the remote, but not from the Door Control: • Is the door control lit? If not, reverse the wires. If the opener runs, check for a faulty wire connection at the door control, a short under the staples, or a broken wire. • Are the wiring connections correct? Review Installation Step 6, page 12. 3. The door operates from the Door Control, but not from the remote control: • Is the door push bar flashing? If your model has the Lock feature, make sure it is off. • Program the opener to match the remote control code. (Refer to instructions on the motor unit panel.) Repeat with all remotes. 4. The remote control has short range: • Change the location of the remote control in your car. • Check to be sure the antenna on the side or back panel of motor unit extends fully downward. • Some installations may have shorter range due to a metal door, foil backed insulation, or metal garage siding. 7. The door doesn't open completely: • Is something obstructing the door? Is it out of balance, or are the springs broken? Remove the obstruction or repair the door. • If the door is in good working order but now doesn't open all the way, increase the up force. See Adjustment Step 2. • If the door opens at least 5 feet (1.5 m), the travel limits may need to be increased. One turn equals 2" (5 cm) of travel. See Adjustment Step 1. Repeat the safety reverse test after the adjustment is complete. 8. The door stops but doesn't close completely: • Review the travel limits adjustment procedures on page 21. Repeat the safety reverse test after any adjustment of door arm length, close force or down limit. 9. The door opens but won't close: • If the opener lights blink, check the safety reversing sensor. See Installation Step 10. • If the opener lights don't blink and it is a new installation, check the down force. See Adjustment Step 2. For an existing installation, see below. Repeat the safety reverse test after the adjustment is complete. 27
