International Comfort Products H8MPV100J20B1 Air Pressure Switch
The main function of the air pressure switch is to sense if the blower fan is doing what it is supposed to do. A good number of pressure switches today may have a reset feature that is manual, from which it would have to be reset manually before the system will continue its normal operation. This is just one of many devices designed to keep everyone in the house safe.
Red Flags that your Air Pressure Switch is About to Fail
- Incorrect voltage range running through the pressure switch.
- System does not get to the correct temp according to the settings on the thermostat.
