A furnace coil is a component in a heating system that is responsible for converting electricity or fuel into heat. It consists of a coil of metal tubing through which a heat transfer fluid, such as air or water, flows to transfer the heat to the surrounding space. Furnace coils are commonly found in electric furnaces and boilers.
Yes it does.
simply by measuring the coil voltage, coil current & power factor.
Could be a drain for the inducer motor if it has one and it depends do you have a a/c coil on your furnace if so it could be a drain for it.
