(2) 2006 We notice again it was not working, this time we called the wholesaler and Venmar in Canada about the problem along with pictures; All Air put that board in. He checked all controls everything good. (3) 2008 We had the same problem and again we put this board in. We pulled out all controls to check is there was a short; everything was clean. (4) 2009 Again the unit was not operating by the control. We again talked to the distributors also Venmar they sent me a recall part to have installed on the motor by the heating guy and a new board. T and T Heating did the work. I shipped the board to Venmar for inspection, did not hear from them for a year, we called them and they had no information for me.

I had electrical out to check my box...everything clean, I am suspecting something is causing the board to blow, could it be motor, I think we replaced that a w
