Turn the Amana thermostat knob to the “Off” position. This helps rotate the shaft into a position for quick alignment when installing the new thermostat knob.
Grab the knob in the center with your fingers. Pull the knob straight off the shaft. The end of the shaft resembles a “D” with the flat side pointing to the left.
Align the flat side of the hole on the back of the new thermostat knob with the flat side of the shaft. Push the knob over the shaft until it stops.
