International Comfort Products PGC018K040A Air Pressure Switch
The reason for the existence of an air pressure type switch is to sense if the primary air circulator is actually running. This pressure switch is one of the most crucial mechanisms designed to keep you from harm. Most air pressure switches have a manual reset feature, which, of course, means that it would have to be reset by hand before the system will continue its normal operation.
Signs to Look for when the Switch is Failing
- The blower fan is unable to function.
- The set temperature seldom fully achieved.
- Incorrect electrical voltage being read from the pressure switch.
