Carrier 39L Air Pressure Switch
The primary function of the pressure switch is to determine whether the primary air circulator is on and running. This pressure switch is one of the key device to stop injuries or explosions. Some particular air pressure switches may have a reset feature that is manual, which, of course, means that it would have to be reset by hand or the whole HVAC system will not continue operation.
Warning Signs of a Declining Pressure Switch
- The proper temperature seldom fully achieved.
- Inaccurate volt range being used by the switch.
- Your heating and cooling system can not operate properly.
