Sold in a convenient blister pack of five, this value pack is ideal for HVAC technicians and service professionals who want to keep critical replacement parts on hand for fast, efficient service calls.
Product Overview
CAD cells serve as the flame-sensing component in oil-fired heating systems. When the burner fires, the CAD cell detects the presence of the flame by measuring changes in light intensity. If no flame is detected within the lockout timing period, the primary control shuts down the burner to prevent unsafe operation. Keeping genuine Beckett CAD cells on hand ensures accurate flame sensing and reliable system performance.
