Product Description

The MESTEK j28r06881 is a replacement control board designed for GG XF Series gas fired unit heaters. The control board manages ignition sequencing, burner operation, and safety shutdown functions within the unit heater system. It serves as the central logic component that coordinates gas valve activation, inducer motor operation, and limit switch monitoring. Licensed HVAC technicians and commercial heating contractors typically source this board when diagnosing control failures, lockout faults, or erratic burner behavior in GG XF Series equipment.

This control board is intended for use in GG XF Series gas fired unit heaters, which are commonly installed in commercial and industrial spaces such as warehouses, garages, manufacturing facilities, and loading docks.
