If you are having multiple problems with your control box it may be cheaper and easier to replace the entire control box rather than replacing individual components. When you buy a new control box for your KM kiln the box will simply slip into the existing hinges on the kiln and the old feeder and thermocouple wires can be connected to the new control box.
Control boxes include a power cord but do not include mounting hardware, screws, feeder wires or thermocouple.
