Ok Mary, Thanks for that.
I have checked several suppliers and this part is back ordered so no matter where you order it the part will take some time to arrive.
You would need to pull the unit out from the wall, take the top panel off by removing the 3 screws along the rear lip. Take the top off, you should see the integrated main control/motor control in the top of the machine, At this point its just going to be a matter of swapping wires from old to new control and a couple of screws.
Below I have included a link where you can buy the part, I like to purchase my parts from this supplier because they offer a 1 year warranty on all their parts plus they allow you to return them even if they have been installed unlike others. Click here
