Hey gptib! Happy to help.
Per our setup guide, Chamberlain, LiftMaster, and Craftsman openers with a round yellow learn button and/or a MyQ logo aren’t compatible with the GD00Z: How To Setup a Linear Z-Wave Garage Controller
Can you check your B4310 for either of those? And what alarm panel are you pairing the GD00Z with? That’ll help us point you in the right direction.
