Carrier 38AE Air Pressure Switch
The primary function of the switch is to see if the blower is doing what it is supposed to do. This is one of many other mechanisms designed to stop injuries or explosions. A lot of switches are designed with a reset that is manual instead of automatic, which makes you reset it by hand before the entire HVAC system will continue operating again.
Common Symptoms of a Declining Pressure Switch
- Furnace is unable to operate at all.
- Inaccurate voltage reading from the switch.
- The set temperature in the house is rarely reached.
