SOURCE: Chamberlain Liftmaster 1246R won't open/close
if youcan hear the motor turning when you hit the remote or wall button the plastic gear in the oprator has been ripped and if you take the cover off you will see all of the whote plastic dust that has come from the gear being shreded. You can replace this gear. you do not have to buy a new operator. it is very easy to replace this gear. I can't tell you were to buy one because I buy all my stuff from a dealer.
99% SURE IT IS THE SAFETY EYES - ALIGNMENT, WIRING, OR BAD EYES
HOPE THIS HELPS

I WOULD RETURN THE NEW REMOTE - THE UNIVERSAL ONES ARE ALWAYS A PROBLEM. WRITE DOWN THE MODEL # AND FREQ. FOR YOUR UNIT AND BUY A UNIT MADE BY CHAMBERLAIN/LIFTMASTER FOR YOUR SYSTEM.
