Unit was kicking on for 5sec and turning off. Cleaned sensor, still no change. Ordered part overnight shipping. Easy repair, save yourself a ton of money and do it yourself.

What can you say about a thermocouple. It works. It has been working for a year. I have two spares pinned to the wall next to the furnace for when it might fail in the future.
