To remove the rheostat from the panel, simply unscrew the one screw that holds it on. It will not come right off, it is still on the two pin electrical contacts. You will need to pull it straight out from the panel - no twisting or you might break off a pin.



I used a small flat-head screw driver to pry it just a little to get is started. Go slow, it will come off pretty easily.




Here are the two pins that the rheostat connects to, be careful not to break them.
