Keep your pellet stove running safely and efficiently with the correct OEM-replacement vacuum pressure switch. The 80P30658-R monitors combustion airflow and shuts the stove down if draft pressure falls out of spec -- protecting the heat exchanger, the auger motor, and your living space. This is the exact switch used across a wide range of St. Croix models and is also catalogued as NBK Parts 20150.
Vacuum pressure switches are a critical safety component in pellet stoves. They confirm that the combustion blower is generating adequate negative pressure (draft) before allowing ignition and continued operation. When this switch fails -- or when it triggers nuisance shutdowns -- your stove may refuse to start, shut off mid-cycle, or display a pressure-fault error code.
The St. Croix 80P30658-R is the factory-specified replacement for the models listed below. Using the correct switch matters: a switch calibrated to the wrong set-point will either allow unsafe operation or cause unnecessary lockouts. Always verify your model number before ordering.
Calibrated to the factory set-point for correct draft detection across all listed St. Croix models. Drops in without modification.
Covers 14 St. Croix pellet stove models including inserts, freestanding units, and multi-fuel variants.
Prevents ignition and shuts down the stove if combustion airflow drops below the safe threshold, protecting components and occupants.
Weighs just 0.5 lbs. Easy to handle during service. Designed for direct plug-in replacement with no harness modification needed on listed models.
The 80P30658-R vacuum pressure switch fits the following St. Croix models:
Common symptoms of a faulty vacuum pressure switch on St. Croix pellet stoves include:
Before replacing the switch, inspect the vacuum tubing (typically a small-diameter rubber or silicone hose running from the combustion blower housing to the switch port) for cracks, kinks, or loose connections. A damaged hose can mimic a failed switch. If the hose is intact and the blower is confirmed operational, the switch itself is the likely culprit.
