I ran this call last week Monday, March 2nd. I ordered a new main control board. I called the customer over the weekend to set up a return call for Monday, March 9th. and was told by the customer that everything has been working OK since I was out. All I did was make sure all the wire connectors were plugged in tight on the control board. My parts distributer is holding the control board for me but wants me to call him if it is not needed to replace it in stock. As of today, he has not called back to say that it stopped working again. If he does, now I have a couple of things to check out before replacing the board. Thanks for the info. I'll let you know how things work out if I go back out.
