TROUBLESHOOTING
1. The operator doesn't operate from either the Door
Control or the remote control:
• Does the operator 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 door spring may be broken. Have it replaced (see page
3 for reference).
2. Opener operates from the remote, but not from the
Wireless Wall Control:
• Check the LED on the Wall Control to ensure the LED turns
on when button is pushed. If the LED is weak or not on
Change the batteries. (Remove cover and replace with
CR2032 batteries X 2)
• If the LED turns on and is strong check to ensure the unit is
programmed into the unit (see page 20).
3. The door operates from the Door Control, but not from
the remote control:
• Is the door push bar flashing? If so, Lock mode is engaged.
Make sure it is off by pressing the
Lock button for two seconds.
• Program the operator to match the remote control code.
(Refer to instructions on the motor unit panel.) Repeat with all
Remote.
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
siding.
5. The 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 control console and the motor
unit.
•
Clear memory and re-program all remote controls.
6. 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.
7. The door opens but won't close:
•
Check cable tension monitor (see installation step 4).
•
If the operator clicks, check the safety reversing sensor. See
Installation Step 9.
•
If the operator does not click and it is a new installation. See
Adjustment Step 2. For an existing installation, see below.
Repeat the safety reverse test after the adjustment is complete.
8. The door reverses for no apparent reason and operator
LED doesnʼt blink:
•
Check cable tension monitor (see installation step 4).
•
Is something obstructing the door? Pull the emergency
release handle. Operate the door manually. If it is
unbalanced or binding, call a trained door systems
technician.
•
Clear any ice or snow from the floor area where the door
closes.
•
Review
Adjustment Step 2.
Repeat safety reverse test after adjustments.
9. The door reverses for no apparent reason and operator
LED blinks for 5 seconds after reversing:
•
Check the safety reversing sensor. Remove any obstruction
or align the receiving eye. See
Installation Step 9.
10. The operator strains to operate door:
•
The door may be out of balance or the springs may be
broken.
Close the door
and use the emergency release
handle to disconnect the door. Open and close the door
manually. A properly balanced door will stay in any point of
travel while being supported entirely by its springs. If it does
not, disconnect the operator and call a trained door systems
technician.
11.The operator motor hums briefly, then won't work:
•
The door springs may be broken. See above.
•
If the problem occurs on the first operation of the operator,
door may be locked. Disable the power door lock.
12.The operator won't operate due to power failure:
•
Manually open the power door lock.
•
Use the emergency release handle to disconnect the door.
The door can be opened and closed manually. When power
is restored, pull manual release a second time.
•
If an EverCharge Unit is connected, the operator should be
able to operate up to 20 times without power.
13. Door loses limits.
•
Collar not tightened securely. Tighten collar
(see Assembly Steps 1 and 2) and reprogram limits
(see Adjustment Step 1).
14. The operator moves when the door is in operation:
•
Some minor movement is normal for this product. If it is
excessive the collar will wear prematurely.
•
Check to make sure the torsion bar is not moving left/right
excessively.
•
Check to make sure the torsion bar is not visibly moving up
and down as it rotates.
•
Check that the operator is mounted at a right angle to the
jackshaft. If not, move the position of the mounting bracket.
15. Power lock makes noise when operating.
