International Comfort Products T8MPL050B12A1 Air Pressure Switch
The actual job of the pressure switch is to sense if the air blower is actually running. This is one of the most crucial facets of the HVAC safety checks that are dedicated to keep you safe. Some particular air pressure switches are equipped with a manual reset feature, which forces the system to be reset physically before the HVAC system will continue.
Signs to Look for when the System Pressure Switch is Going Bad
- Inaccurate electrical voltage being read from the pressure switch.
- The proper temp is almost never attained.
- The furnace refuses run.
