If you allready have the new switch, you are ready to start. If you do not have the part, it is available at www.sears.com
under the parts direct tab. you'll need your model number to search out you machine and then the switch.
I find it easiest to remove the entire main case to make this repair. Case removal is as follows:
Disconnect the power cord. 1. There are two screws, one at each front corner, holding the control panel in place, remove them. 2. Remove the two screws at the top, on the back of the control panel. Carefully roll the control panel over the back. 3. Unplug the wire that connects the control panel to the top. Stop here and take note as to how the case connects to the back panel. There is an aligner there that will be your hardest part to deal with later. This will help when reassembling. 4. OK, Put a slotted screw driver into the front of the clips, at the back corners on the top and push back to release them, once again take note to their positioning. 5. The outer case hooks under the front of the frame and the sides have a slot that goes over a pin near the back of the frame side. (Front under, sides on top of frame)Tilt the case up on back and pull forward. Congrats you are there. Replace the switch and reassemble reversing procedure. Good luck. Need help? I'm here.
