The shaft of the original Temp Selector switch was snapped off during moving.

Just remove the 2 screws out of the 4 that are on the top ends of the Control Panel. (Unplug first!)

Then lay the panel forward, remove the 1 screw holding in the temp switch, and put in the new switch.

Transfer the 4 wires (fast-ons) from the old switch to the new, and put the panel back in place, reinstall the 2 screws. Finished. Plug in & test the different settings for the correct water temp coming in throught the inlet.
