Bard S8402-028 Limit Control this component ensures a gas-tight

this component ensures a gas-tight interface between the burner and the air manifold

it resolves common fault codes related to airflow verification and pressure switch stuck open or closed errors

This high temperature limit control is built for high-duty cycles

replacing a brittle or cracked ignition lead often restores the circuit path

but the unit must never be left in operation without a functional limit switch in the safety circuit

Bard S8402-028 Limit Control this component ensures a gas-tightThe Bard S8402 028 Limit Control is a critical OEM safety component engineered for Bard wall mount HVAC units and similar industrial climate control systems. This high limit switch is designed to protect the heat exchanger and internal components from thermal damage by monitoring air temperatures within the plenum. Operating with a 150F open and 125F close configuration, it ensures the burner or heating elements are de energized if the system exceeds
