Description
Robertshaw brings reliability, quality and compatibility together in a cost conscious replacement ignition control board. For use with standard 120 VAC Silicon Carbide hot surface igniter elements, the control board was designed to meet or exceed OEM requirements. Microprocessor monitoring of the thermostat, inducer pressure switch, thermal limits and flame current input is constant. The software verifies program code integrity and general microprocessor health continually to insure the highest level of safety. LEDs display industry-familiar error blink codes to help diagnose field problems.
