International Comfort Products PGAD24B1K1 Air Pressure Switch
The primary function of the switch is to determine whether or not the primary blower is actually running. This pressure switch is part of a small, but important collection of devices designed to keep you from harm. Most air pressure switches are programmed with a manual reset, from which the switch will have to be manually reset before the HVAC system will continue.
Clues that your Pressure Switch will Soon Fail
- Furnace will not operate.
- The proper temp is never reached.
- Inaccurate volt range running through the pressure switch.
