Operation
MAINTENANCE SCHEDULE
Once a Month
• Manually operate door. If it is unbalanced or binding, call a trained door systems technician.
• Check to be sure door opens & closes fully. Adjust limits and/or force if necessary (see Adjustment Steps 1 and 2).
• Repeat the safety reverse test. Make any necessary adjustments (see Adjustment Step 3).
Once a Year
• Oil door rollers, bearings and hinges. The garage door opener does not require additional lubrication. Do not grease the door tracks.
The garage door opener doesn't operate from either the door control or the remote control:
• Does the garage door 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 (see page 3 for reference).
Garage door opener operates from the remote, but not from the door control:
• Is the door control lit? If not, reverse the wires. If the garage door 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 5, page 11.
The door operates from the door control, but not from the remote control:
• Is the door push bar fl ashing? If so, Lock mode is engaged. Make sure it is off by pressing the Lock button for two seconds.
• Program the garage door opener to match the remote control code. (Refer to instructions on the garage door opener panel.) Repeat
with all remote controls.
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 the garage door opener extends fully downward.
• Some installations may have shorter range due to a metal door, foil backed insulation, or metal garage siding.
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 garage door opener.
• Clear memory and re-program all remote controls.
The door doesn't open completely:
• Check power door lock.
• Is something obstructing the door? Is it out of balance, or are the springs broken? Remove the obstruction or repair the door.
