These instructions walk you through the process of replacing 3 Heat switches in KilnSitter Kilns. All KilnSitter models use 3-Heat switches except for models 818, 818P, 183, 185, and 614 which use an Infinite Switch. These instructions are for installing the old style 3 heat switch which is no longer available. If you have purchased a 3-Heat switch recently please use the “New Style 3-Heat Switch Conversion Instructions” below.
These instructions are for installing the new style 3-Heat switches on kilns manufactured prior to November 6th, 2018. The connections on the new switch are different so it will involve installing new connectors on your wires.
