LiftMaster 41A5021-1HATS Receiver Logic Board Assembly for ATS211X and ATS211R - 390 MHz
The LiftMaster 41A5021-1HATS is a receiver logic board assembly for select older ATS211X and ATS211R garage door opener applications. It is associated with 390 MHz radio technology and related 41A5021-style board numbers.
This part is used on older LiftMaster and Chamberlain opener platforms where the original board number and radio system match the replacement. It should not be guessed by opener age or housing style alone.
What This Part Does
The board controls receiver functions and key opener logic functions. It receives compatible remote signals, communicates with connected controls, and operates the opener according to the board and accessory wiring.
A failed board may cause no response, remote programming failure, intermittent operation, light/control issues, or opener logic problems. Similar symptoms can also come from wall controls, safety sensors, wiring, power supply, or motor problems.
