I call bull on the 2 years! I've got a lot of stoves out there way over 5 years that have never had one. Wouldn't make sense if you had to put that kind of money into it every 2 years.

I was thinking the same way, my first box lasted almost 4 years. A near by lighting strike took it out. Don't understand what happened to the 2nd one. Running along then POP! Transformer smelled burnt. Hope this one lasts another 4 years at least.

Just popped another box, made it 3 and a half hours. The heat sink on the box is to hot to even touch.

Good thing for the 90 day warranty, if they will cover it. You've got a short somewhere. I would be pulling the fuse holder and taking a look at that. I've seen holes melted right through them.

The first time the fuse blew, this time it did not.

Checked every inch of wiring no nothing. Pulled the assembly the control board sits on, everything looks good. No idea where to look now.
