Carrier 58MVP Air Pressure Switch
The main function of the switch is to sense whether the air blower is running properly. Some pressure switches are equipped with a manual reset feature, which, of course, means that it would have to be reset by hand or the whole HVAC system will not continue operation. This switch is part of a small, but important collection of hardware devices made to keep you safe.
What to Look for when the HVAC Air Pressure Switch is Starting to Go Bad
- HVAC system can not operate properly.
- Incorrect electrical voltage running through the pressure switch.
- The proper temp is rarely reached.
