International Comfort Products HPFM36K000A Air Pressure Switch
The reason for the existence of the switch is to determine whether or not the blower is blowing air. This pressure switch is one of many other facets of the HVAC safety checks that are dedicated to keep you from harm. A lot of switches are constructed with a manual reset, which forces the system to be reset physically before the entire HVAC system will continue operating again.
Signals that the Air Pressure Switch is Needing to be Replaced
- The blower fan refuses to operate properly.
- Inaccurate voltage running through the switch.
- The correct temperature indoors is almost never achieved.
