Carrier 48GS018040300 Air Pressure Switch
The job of this type of switch is to determine whether or not the main blower is doing what it is supposed to do. This switch is part of all the safety features in today's HVAC systems in place to keep you safe from harm. A good number of pressure switches today may have a reset feature that is manual, which, of course, means that it would have to be reset by hand in order for the HVAC system to continue running.
Clues that your Switch will go Bad
- The desired temperature in the house seldom reached.
- Wrong volt range reading from the switch.
- Furnace can not ignite.
