Carrier 38QRF018 Air Pressure Switch
The job of the switch is to sense whether the blower fan is blowing air. A lot of switches can have a manual reset, which means you have to physically reset it or else the system will cease to function. This is part of a small, but important collection of devices designed to keep you from harm.
What Signs are Present when the HVAC Air Pressure Switch is Beginning to Go Bad
- Incorrect volt range running through the pressure switch.
- The furnace or AC is unable to run.
- The right indoor temperature is almost never fully achieved.
