Carrier 48JZ060115300 Air Pressure Switch
The job of the pressure switch is to sense whether the main blower is doing what it is supposed to do. An air pressure switch is one of the vitally important safety device to keep you from harm. The vast majority of pressure switches made today are issued 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.
Red Flags that your Pressure Switch is Beginning to Go
- The correct temperature is rarely fully achieved.
- Bad volt reading from the switch.
- The furnace or AC refuses to function.
