4 Test the Power Door Lock

garage door. When the door reaches the fully closed

function, contact Chamberlain for a replacement.

Test the Cable Tension Monitor
1. Close the garage door.
2. Pull down on the emergency release handle until you
hear a click.
3. Press on the front of the cable tension monitor, you
should hear a click.
4. Reconnect the garage to the garage door opener.
If there is no click, the roller may be hitting the jamb and
not allowing the switch to detect slack in the cable. Make
sure the cable tension monitor is mounted flush with the
wall and the roller is free from any obstructions.
When the cable tension monitor has been activated, the
LED on the garage door opener will blink 9 times.
To prevent possible SERIOUS INJURY or DEATH from
a falling garage door:
• If possible, use emergency release handle to
disengage door ONLY when garage door is CLOSED.
Weak or broken springs or unbalanced door
could result in an open door falling rapidly and/or
unexpectedly.
• NEVER use emergency release handle unless garage
doorway is clear of persons and obstructions.
