Carrier 38YZA042 Air Pressure Switch
The reason for the existence of the air pressure switch is to determine whether the air blower is running. An air pressure switch is one of the most crucial devices that are created to keep you from harm. Some pressure switches are constructed with a manual reset, which forces the system to be reset physically before the system will continue its normal operation.
Signs to Look for when the HVAC Air Pressure Switch is About to go Bad
- The blower is unable to run correctly.
- Wrong voltage range being read from the pressure switch.
- System does not get to the correct temp.
