International Comfort Products H8MPN100F14B1 Air Pressure Switch
The job of the pressure switch is to determine whether or not the air blower is circulating the air as it should. This switch is a very critical piece of the collection of safety devices in place to keep you safe from harm. Most air pressure switches are issued with a manual reset feature, which means you have to physically reset it before the entire HVAC system will continue operating again.
Red Flags that your Pressure Switch is Starting to Go
- The set temp is rarely fully attained.
- The furnace or AC will not operate.
- Inaccurate electrical voltage being read.
