International Comfort Products T9MPT050F12B1 Air Pressure Switch
The actual job of the switch is to see if the blower fan is actually running. This switch is one of the vitally important safety aspects of the whole safety system that is intended to stop injuries or explosions. A lot of switches are equipped with a manual reset feature, which means it will have to be manually reset before the entire HVAC system will continue operating again.
Symptoms that your Air Pressure Switch is Starting to Go Bad
- Wrong volt range being used by the switch.
- The desired temperature indoors is never fully achieved.
- The blower fan can not run.
