Carrier 38YXA048 Air Pressure Switch
The main function of the air pressure switch is to determine whether or not the air blower is blowing air. A good number of pressure switches today are equipped with a manual reset feature, which forces the system to be reset physically before the entire HVAC system will continue operating again. This is one of many other mechanisms designed to keep everyone in the house safe.
Signs that your HVAC Air Pressure Switch is Already Failing
- System does not actually get to the right indoor temperature.
- Incorrect volt being read from the pressure switch.
- HVAC system refuses to function properly.
