LFM-20 Evolve for garage door

Yea, I’m pretty sure I’m hooking the up right. I just wire power in directly from a plug, and have the two blue wires straddle the two terminals on the garage door where the buttons attach. So basically the relay just pushed the button. It all works perfectly. Right up until it doesn’t. And then the units are dead. No indicator light. Nothing. Just dead. 3 of them in 1 year.
