This replacement part (Model: SRV7000-166, Marked Number: NS2-1514-00) is a high-precision differential vacuum pressure switch, engineered to directly replace the listed part numbers for applicable pellet stove models. As a safety-designed air switch, it ensures that your inducer motor is running at the proper RPM, and creating the proper vacuum for your furnace to flue safely. Configured with a 0.05" WC pressure rating and 2-terminal quick-connect design, it acts as a critical safety interlock by monitoring negative pressure in the firebox and exhaust flue—preventing auger fuel feeding until proper venting is confirmed to avoid dangerous fuel buildup. The package includes 12" and 36" black tubing to fit different installation spaces, eliminating the need for separate purchases. Constructed with high-temperature resistant plastic housing, it withstands harsh stove environments and maintains stable performance through repeated on-off cycles. This sensor resolves common issues like failure to feed pellets, intermittent shutdowns, draft-related error codes, and safety system malfunctions caused by worn switches.
