Carrier 25HNA660A0030020 Air Pressure Switch
The reason for the existence of this type of switch is to figure out if the blower is running properly. An air pressure switch is part of a small, but important collection of devices that are created to keep everyone in the house safe. Some pressure switches may have a reset feature that is manual, by which you must manually reset it before you can continue using the system.
Precursors that the HVAC Air Pressure Switch is Failing
- Inaccurate voltage reading.
- The set temperature is rarely fully attained.
- The blower fan will not run.
