Carrier 38YRA042 Air Pressure Switch
The function of the air pressure switch is to sense if the main blower is blowing air. The vast majority of pressure switches made today may have a manual reset, which forces the system to be reset physically or the whole HVAC system will not continue operation. This is one of the vitally important safety facets of the HVAC safety checks that are dedicated to keep you safe.
Symptoms that your HVAC Air Pressure Switch is Beginning to Go
- Your furnace is unable to operate.
- The correct temperature in the house is hardly ever reached.
- Inaccurate volt range being used by the switch.
