4 - Remove the old thermostat control (screws). The wire runs up the side, along the top to the other side.

5 - Remove the thermostat. Drill out rivets starting at the wire end and try to wiggle it out. I was able to remove mine by only removing 2 rivets instead of all 4.

6 - Slide the new thermostat through the hole in the side of the cabinet. Secure with new rivets (1/8").

7 - Run the wire along the top of the unit, and secure the control in the panel. Extra slack in the wire can be folded along the top. That's how I found the original.

8 - Install the control panel and knobs.

9 - Install the insulation (gloves are your friend).

10 - Install the cover. This might take extra hands to keep all locking tabs aligned to get the screw installed.
