International Comfort Products NAC236GKA1 Air Pressure Switch
The main job of an air pressure type switch is to sense if the primary blower is on and running. Some pressure switches can have a manual reset, which forces the system to be reset physically before you can continue using the system. This switch is one of the vitally important safety facets of the HVAC safety checks that are dedicated to keep everyone in the house safe.
Precursors that the Air Pressure Switch is Already Failing
- The desired temperature seldom attained.
- Bad volt range reading from the switch.
- The furnace will not ignite.
