Carrier 48XPN060130300 Air Pressure Switch
The main job of the switch is to see if the blower is doing what it is supposed to do. Some pressure switches are issued with a manual reset feature, which, of course, means that it would have to be reset by hand in order for the HVAC system to continue running. This is one of the key mechanisms designed to keep you from harm.
How is it Known when the Switch is Failing
- Wrong volt range running through the switch.
- Your furnace refuses ignite the gas.
- The desired temperature in the house seldom achieved.
