Master Lock ATS 211 - Manual (Page 26)

1. Have you disabled all door locks? Review installation instruction warnings on page 7.
2. 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.)
3. Repeated operation may have tripped the overload protector in the motor. Wait
15 minutes. Try again.
4. Is there a build-up of ice or snow under the door? The door may be frozen to the
ground. Remove any restriction.
5. Remove the bell wire from the opener terminal screws. Short the red and white
terminals by touching both terminals at the same time with a piece of metal
(screwdriver or coin). If the opener runs, check for a faulty wire connection at the
door control or a short under the staples.
Having a Problem?
Situation Probable Cause & Solution
The opener doesn't
operate from either
the Door Control or
a remote control:
Opener operates
from a remote
control, but not
from Door Control: 1. Are the wiring connections correct? Review Step 6, page 13.
A remote control
has short range:
The garage door
opens and closes
by itself: 1. Check to be sure that a remote control push button is not stuck in the "down" position.
2. Remove the bell wire from the Door Control terminals and operate from a remote
control 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 opener.
The door doesn't
open completely: 1. Is something obstructing the door?
2. If door opens at least 5 feet, the travel limits may need to be increased. One turn
equals 2 inches of travel. See page 21.
Repeat the safety reverse test after the adjustment is complete.
3. If the door has been working properly but now doesn't open all the way, increase the
up force. See page 22.
Repeat the safety reverse test after the adjustment is complete.
The door doesn't
close completely: 1. Is something obstructing the door?
2. Review travel limits adjustment procedures on page 21.
Repeat the safety reverse test after any adjustment of door arm length, close
force or down limit.

1. Check the battery test light. If the light is dim, change the battery.
2. Change the location of the remote control in the car.
3. A metal door, foil-backed insulation or metal garage siding will reduce the
transmission range.
4. Check to be sure the antenna on the back panel of opener extends fully downward.
Install Antenna Kit, Part No. 41A3504, to increase range.
Opener noise is
disturbing in living
quarters of home: 1. If operational noise is a problem because of proximity of the opener to the living
quarters, the Vibration Isolator Kit 41A3263 can be installed. This kit was designed to
eliminate the "sounding board effect" and is easy to install.
