International Comfort Products PGC048H120F Air Pressure Switch
The primary function of this type of switch is to sense if the primary blower is circulating the air as it should. Some pressure switches may have a reset feature that is manual, from which it would have to be reset manually or the entire system will not run. This is one of the vitally important safety hardware devices made to keep your family safe and sound.
Important Signs that the Pressure Switch is Already Going Bad
- HVAC system does not actually get to the right temp.
- Incorrect voltage reading.
- The furnace is unable to run.
