Doorbell Pro Bricked two times.

My new construction house used the Nicor eleteronic chime which outputs 18v AC and 125mA. It's on Ring's compatabilty list but it's bricked two units at this point. They both installed/setup fine, no diode as instructed by Ring's website and worked for around 10 mins then the Ring app said they had lost wifi. I checked the doorbell and the blue ring was lit it and it was flashing in the lower left corner. I figured ok...I got a defective unit. Got it replaced. Same exact thing. The unit was very hot when I disconnected power from it. Wouldn't hard reset, nothing. Just sat there and blinked blue in the lower left corner. When I turned the breaker back on eeach time the chime kept going off over and over and over for like 2 mins before stopping as well. In the end I'm going with the 3 Plus because when they installed the wiring for my new house they put it 2 feet to the right of the door molding for some reason. It looks better and gets better coverage putting it on the door molding even using the corner wedge on the Ring Pro. Am I just an idiot and did something wrong?..lol It's not blinking like it's charging either.
