Carrier 38EYA036 Air Pressure Switch
The function of an air pressure type switch is to sense whether the primary air circulator is doing what it is supposed to do. This pressure switch is one of the vitally important safety mechanisms designed to keep you safe. The vast majority of pressure switches made today are equipped with a manual reset feature, which, of course, means that it would have to be reset by hand before the system will continue its normal operation.
Symptoms that the Pressure Switch has Failed
- The expected temperature is almost never fully attained.
- HVAC system refuses to operate.
- Inaccurate voltage reading.
