How do I test the main board to see if it is bad. I have power to it. A new board cost $140 so I want to make sure the old one is bad before I buy a new one—Jim—
If it is just dead, you might have a blown thermal fuse, a white plastic part that plugs into the control board.
I cheaked the fuse its ok
Seems like you need a new board.
how do I tell if the board that has the control buttons is bad? 
I assumed the control module did nothing, power to it and no function, is this correct?
Yes. That’s right. The control panel has no power. It dose not work.right .
So you measured voltage on the board side of the fuse, right.
yes I have voltage to the board.
There is no other item that will cause the board not to work, except a missing power ground. If you measure voltage to the board and the other lead to power ground on the board, usually a white wire= new board time.
Ok Thanks for your help. I’ll order a new board. they are $150 bucks so I wanted to make suri I need one
