Payne PG8MAA042090AAJA Air Pressure Switch
The actual job of the air pressure switch is to determine whether the blower fan is doing what it is supposed to do. This pressure switch is one of the key mechanisms designed to keep you from harm. The vast majority of pressure switches made today are constructed with a manual reset, by which you must manually reset it or else the system will cease to function.
Symptoms that your HVAC Air Pressure Switch is Beginning to Go
- Bad volt range being read from the pressure switch.
- The furnace refuses operate at all.
