Samsung MH080FXCA4A Air Pressure Switch
The main function of this type of switch is to determine whether the blower fan is actually running. Various air pressure switches are constructed with a manual reset, which means you have to physically reset it before the entire HVAC system will continue operating again. This is one of the vitally important safety creations designed to keep you from harm.
Signs to Look Out for when the HVAC Air Pressure Switch is on its Last Leg
- The furnace refuses operate.
- Wrong voltage reading from the switch.
- The set temperature seldom achieved.
