Robertshaw 10-681 Flame Sensor Carrier LH33WZ511

The Robertshaw 10-681 Flame Sensor Carrier LH33WZ511 detects burner flame by sensing flame rectification during equipment operation. It sends a verification signal to the ignition control circuit, allowing fuel flow only when the required flame is present in HVAC systems. Positioned adjacent to the burner assembly, this sensing component continuously monitors combustion status and communicates operating status to connected safety controls. Its responsive detection operations support timely protective operations while assisting controlled burner operation and maintaining safe equipment performance during proper service conditions.
