Carrier 38BK Air Pressure Switch
The function of this type of switch is to sense if the primary air circulator is doing what it is supposed to do. The vast majority of pressure switches made today can have a manual reset, which forces the system to be reset physically or the entire system will not run. This switch is one of many other hardware devices made to keep everyone in the house safe.
What to Look Out for when the Switch is Beginning to Go
- The blower refuses to run correctly.
- Wrong voltage reading.
- System does not achieve the desired temperature when set by the thermostat.
