Question about Sears Craftsman LiftMaster Chamberlain Garage Door Opener Wireless Keypad Model 976LM Security+
MANY NEWER DOOR OPENERS ACTIVATE THE LIGHT EACH TIME YOU BREAK THE SAFETY SENSOR BEAM.
THE LIGHT SHOULD STAY ON FOR ABOUT 4.5 MINUTES EACH TIME THE OPENER MOVES OR THE BEAM IS BROKEN.
DOES YOU WALL CONTROL HAVE A LIGHT BUTTON??
IF NOT THE CIRCUIT BOARD STILL HAS THE ABILITY TO WORK WITH ONE THAT DOES. I HAVE SEEN SOME WHERE THE ONLY WAY TO TURN OFF THE LIGHT WAS TO CONNECT A 3 BUTTON WALL STATION & TURN OFF THE LIGHT - THEN RECONNECT THE PUSH BUTTON - OR YOU COULD LEAVE THE 3 BUTTON WALL CONTROL.
YOU MAY ALSO TRY UNPLUGGING THE UNIT FOR ABOUT 5 MIN. THIS RESETS MANY OF THE CIRCUITS ON THE BOARD.
HOPE THIS HELPS

have your lights come on automatically when you walk into an open
garage, you must START with the lights ON. If you don't want that
feature and you want to turn it off, you must START with the lights
turn the feature on, turn the lights on manually with the wall
switch, then press and hold the LIGHT button for about 10 seconds
until the motor unit light bulbs flash. Now, if the light bulbs are
on, manually turn them out and then walk out through the open door.
The light bulbs should come on.
disable this feature, start with the light bulbs OFF and everything
else is the same.
