International Comfort Products PAF Air Pressure Switch
The job of the air pressure switch is to determine whether the blower fan is actually running. This switch is one of many other safety creations designed to keep you safe. Some particular air pressure switches may have a manual reset, which means you have to physically reset it in order for the HVAC system to continue running.
Precursors that the Switch is Starting to Go
- Inaccurate voltage range being used by the switch.
- HVAC system refuses to function properly.
- The expected temperature indoors is never attained.
