New TT and Dometic refer/freezer is dead on AC?!

I had mine start doing the same thing after a year. It ended up being something on the circuit breaker that controlled the auto feature. Not sure if that it what's wrong with your unit, but it's behaving the same way.

First tech that looked at it for me, said it's was fine. I emailed the manufacturer and they diagnosed it right away. I used it for months on gas only until I took it back in for other work and they fixed the board. It's all good now.

Good luck man!
