Lochinvar & A.O. Smith 100110973 Switch 326010-701 Reliable Sensing: Optimizes microamp signal

Reliable Sensing: Optimizes microamp signal feedback to the control board to prevent false shut-offs

Technicians frequently utilize this part to restore functionality to systems where the control circuit has failed due to a shorted contactor coil or primary surge

Direct Immersion Design: Eliminates the need for a separate well (in most direct-mount scenarios)

Smith 100110973 Blocked Flue Switch is a critical safety component designed for high efficiency boilers and commercial water heaters. As a veteran technician knows, this negative pressure switch (often referred to as a spill switch) is engineered to sense obstructions in the venting system, protecting the heat exchanger from hazardous flue gas recirculation. When the integrated sensor detects a lack of proper draft or a blocked
