Found replacing the switch to be doable, but it was quite a delicate operation. This was for a Thermador range with a broken downdraft switch. It required the removal of 5 small screws which could easily be fumbled and dropped down where it would be difficult, if not impossible to retrieve. Two of the screws were facing the back, so it was a blind operation to remove and replace the screws. Required an offset screwdriver, as space was tight. So, be EXTREMELY careful to not drop the screws and put rags over any openings/cracks that the screws could fall down into. The other tricky part is that there isn't much slack in the wires to the switch, so you have to be careful to not let the disconnected wires drop down where they would be difficult/impossible to retrieve. There are two white wires to connect, so be certain you are not mixing them up by comparing the wire layout to the old switch before you disconnect it! I was very relieved when it was all over and I didn't drop any screws or lose my hold on any of the 3 wires. Even more relived when I turned power back on to the stove and everything worked great!
