International Comfort Products PHF042K000A Air Pressure Switch
The main job of this type of switch is to determine whether or not the primary blower is blowing air. This pressure switch is part of all the safety features in today's HVAC systems in place to keep you safe from injury or explosions. Most air pressure switches have a manual reset feature, which, of course, means that it would have to be reset by hand or the entire system will not run.
What Signs are Present when your Pressure Switch is Needing to be Replaced
- The set temperature indoors is never fully achieved.
- Incorrect voltage range reading from the switch.
- The blower fan refuses to run.
