The model 41A4252-7G circuit board is a replacement logic board that works with garage door openers from several major brands, including Sears Craftsman, LiftMaster and others. This circuit board is a direct replacement part for the LiftMaster Chamberlain 41A4252-7G garage door opener circuit board. It is not compatible with Security+ systems but works with various non-code-rolling LiftMaster openers, as well as other brands. Note that the final digit of the model number (in this case, "G") has no significance except to indicate the model year, so this circuit board will replace any other circuit board numbered 41A4252-7.
Compatible models of garage door openers include these LiftMaster models:

This circuit board is a replacement for the following receiver board models:
Other compatible non-Security+ systems include Master Mechanic, Sears, Tru-Value and Wayne Dalton. For a complete list of LiftMaster circuit boards and the appropriate applications, see our Chamberlain LiftMaster Garage Door Opener Circuit Board Compatibility Chart.
We recommend using the LiftMaster 990LM Garage Door Opener Surge Protector
when replacing safety sensors or circuit boards and North Shore Commercial Door offers a special combo price when you buy both the surge protector and the circuit board at the same time.
