Carrier 48XZ036090300TP Air Pressure Switch
The primary function of the air pressure switch is to sense whether the primary air circulator is actually running. This switch is a very critical piece of the safety system that is in place to keep you safe from any injuries. The majority of pressure switches may have a manual reset, by which you must manually reset it before the entire HVAC system will continue operating again.
Symptoms of a Declining Pressure Switch
- The blower fan can not operate.
