Question about Sears Craftsman LiftMaster Chamberlain Garage Door Opener Wireless Keypad Model 976LM Security+
Began with opening ending with a loud "pop", then door would go limp, until i pushed button on remote and track would return to arm and finish the closing. Then in my return, I would push the open button, the door would lift, almost completely, then "pop" and go limp. Now the control track only makes a loud grinding noise.
To answer your question the opener is in vacation mode. Press and hold for 3 seconds the button on your wall control with the lock icon. The green light will stop flashing and you will be back in business.

Sounds like a skinned wire on your front or rear limit switches is touching metal. Go over your low voltage wiring and test again.

If the small light in your wall control is blinking it is in the lock mode. Press and hold for 3 seconds the button with the icon of a lock. This will toggle the lock function off.
