International Comfort Products H9MPT125L20A1 Air Pressure Switch
The primary function of an air pressure type switch is to sense if the blower fan is blowing air. Most air pressure switches can have a manual reset, which, of course, means that it would have to be reset by hand before the HVAC system will continue. This switch is one of many other mechanisms designed to stop injuries or explosions.
Signals that the HVAC Air Pressure Switch is Needing to be Replaced
- Wrong volt reading.
- The set indoor temperature is never attained.
- Your furnace refuses operate.
