Carrier 38YSA042 Air Pressure Switch
The actual job of the air pressure switch is to sense if the main blower is blowing air. This is one of the critical hardware devices made to keep your family safe and sound. The vast majority of pressure switches made today are programmed with a manual reset, by which you must manually reset it before the HVAC system will continue.
Symptoms to Look for when your Pressure Switch is About to go Bad
- The set temperature is hardly ever fully achieved.
- The blower fan is unable to operate.
- Wrong electrical voltage being read.
