International Comfort Products T8MPV050B12C1 Air Pressure Switch
The reason for the existence of this type of switch is to sense if the main blower is running properly. This switch is one of many other aspects of the whole safety system that is intended to keep you safe. A good number of pressure switches today have a manual reset feature, from which the switch will have to be manually reset before the entire HVAC system will continue operating again.
Precursors that the System Pressure Switch is Beginning to Go Bad
- The blower fan will not function properly.
- The expected temperature in the house is almost never achieved.
- Bad electrical voltage being read from the pressure switch.
