The function of the switch is to determine whether or not the main blower is running properly. The majority of pressure switches may have a reset feature that is manual, by which you must manually reset it before the system will continue its normal operation. This pressure switch is one of the vitally important safety creations designed to keep your family safe and sound.
How do you Know when the Switch is in Need of Replacement
- Incorrect electrical voltage running through the pressure switch.
