International Comfort Products PGAD24B1K4 Air Pressure Switch
The main job of the pressure switch is to see if the primary blower is running properly. This pressure switch is part of a small, but important collection of safety creations designed to stop injuries or explosions. Some pressure switches are programmed with a manual reset, by which you must manually reset it before the entire HVAC system will continue operating again.
What to Look for when your Pressure Switch is Beginning to Fail
- Incorrect voltage reading from the switch.
- Your furnace will not run.
- The expected temperature in the house is hardly ever fully attained.
