Carrier 38ESA042 Air Pressure Switch
The main job of this type of switch is to sense if the blower fan is circulating the air as it should. Most air pressure switches may have a manual reset, which forces the system to be reset physically before the entire HVAC system will continue operating again. An air pressure switch is one of many other safety creations designed to keep you safe.
Symptoms that your Switch is About to Fail
- Furnace can not ignite.
- The set temp is rarely achieved.
- Incorrect voltage being used by the switch.
