Could not change the temp control buttons.

Removed the back panel, 6 screws. Removed the two wires, marked the placement by colors on the new switch. Unscrew the two screws holding the switch. I had to file the front panel a little to the right for the switch to fix. Replaced the switch, screws and back panel. That's all, very easy and it works. I was very happy to find the part, Thank you!
