Carrier 58MSA12012120 Air Pressure Switch
The primary function of the switch is to see if the blower is actually running. The majority of pressure switches are issued with a manual reset feature, which means it will have to be manually reset before the HVAC system will continue. This is part of a small, but important collection of device to keep everyone in the house safe.
Precursors that the HVAC Air Pressure Switch is Failing
- Incorrect voltage range running through the pressure switch.
- Furnace won't ignite.
- The correct temperature in the house is almost never achieved.
