Honeywell Gas Control Testing, Disassembly, and Replacement

The Gas Control is made up of (5) major components; the control cover, the piezo igniter, the valve body, the temperature
sensor, and the back plate. The Gas Control is designed so that any of these components may be replaced without
replacing the entire Gas Control.
