Carrier 25HPA530H0030010 Air Pressure Switch
The reason for the existence of the switch is to see if the blower is on and running. The vast majority of pressure switches made today are constructed with a manual reset, which makes you reset it by hand before the system will continue its normal operation. This pressure switch is one of many other mechanisms designed to keep you safe.
What to Look for when your Pressure Switch is Starting to Fail
- The proper temperature indoors is hardly ever reached.
- Bad volt range reading from the switch.
- The blower can not operate properly.
