Having A Problem - Chamberlain 3595S 3/4 HP Owner's Manual

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.
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 fl ashing? 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.
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.
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, the travel limits may
need to be increased. One turn equals 3" (7.5 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 next page.
Repeat the safety reverse test after the adjustment is
complete.
