Now the engineer says even though his fan is running good his temps are still 5 - 9* F too high. He is thinking of paint now. haha! We all have been down that road before. Once he paints it, his temps will drop back a couple of degrees, but still be too warm. The next step would be to add a chimney for the heat to escape...Is it worth all the frustration?
Well, that's to be expected. He's pretty much all bluster.
The "solution" (if any) will eventually have to come from Acurite. That's why I keep advising people to return their defective equipment.
If the problem were simple, it would have been found by now.
