International Comfort Products HAC230GKA4 Air Pressure Switch
The main job of the air pressure switch is to sense if the air blower is doing what it is supposed to do. This switch is one of the vitally important safety creations designed to keep everyone in the house safe. Some pressure switches can have a manual reset, which means it will have to be manually reset or the whole HVAC system will not continue operation.
What Signs are Present when the Switch is in Need of Replacement
- The desired temp is almost never fully attained.
- Bad voltage running through the switch.
- The blower fan can not run correctly.
