International Comfort Products PGF042K100F Air Pressure Switch
The main job of the switch is to sense if the blower fan is running properly. Some different switches are programmed with a manual reset, from which the switch will have to be manually reset before the HVAC system will continue. This is just one of the many indispensable safety creations designed to keep everyone in the house safe.
Symptoms that your System Pressure Switch is Already Failing
- The blower can not function.
- Wrong volt reading.
- The expected temperature in the house is almost never reached.
