I have an old double door wood stove with a 3-speed thermostat (CPI bar). It only works on high. What is needed to make it 3 speeds again?
The CPI bar is no longer available. You will need to replace your CPI bar with a CPI replacement kit, which consists of a thermostat disc, rheostat, rheostat knob, and the wiring schematic. This replacement kit is variable speed (not 3 speed like the older CPI bar) and is adjusted with the rheostat knob. Order part # MA 100120.
