Congrats Rob on getting it fixed, yup it was pricey but ya don't have to hassle with getting a new one and installing it.
Ksrmd, you might want to post a new thread so the real techs like denman will be sure to read it, he will likely even send you spec drawings. If your unit is like most, you will need to remove the inner door panel, probably with the right size torx bit, then disconnect a wire or two with quick connects. The control board is probably up behind there, and is easliy removed, helps to have a small 1/4 inch drive socket set. But somtimes you can spend big bucks on a control circuit board, but then find the problem is the control panel or somthing else.
