International Comfort Products PGAA36C1K6 Air Pressure Switch
The main job of the air pressure switch is to sense whether the blower is doing what it is supposed to do. This switch is one of many other hardware devices made to keep you safe. A lot of switches are equipped with a manual reset feature, which means you have to physically reset it before the system will continue its normal operation.
What to Look Out for when the HVAC Air Pressure Switch is Starting to Fail
- Incorrect volt reading.
- Your system doesn't reach desired temp.
- The blower is unable to operate.
