Due to customer feedback, recent changes have been made to the control boards and expansion boards used on LiftMaster Gate Operators.

The following changes have been made to the control boards;

• Accessory power on the main control board (K1D6761-1CC) for all AC gate operators will now have 24VDC, 500mA instead of 24VAC, 500mA accessory power. This board change is effective on gate operators manufacture after August 1, 2018
• DC pad and linear actuator boards manufacture after August 1, 2018 have improved power line and lightning surge protection

The following changes have been made to the expansion board;

• Main expansion board (K1D838-1CC) for all gate operators has been updated with an extra connector (J7) to accommodate power for the wireless edge receiver (MLWEKITU). There will be no need to use the extra I2C Interface board that comes with the LMWEKITU.
