Frigidaire FRP90PTT2A0 Air Pressure Switch
The primary function of the switch is to determine whether or not the blower fan is circulating the air as it should. Various air pressure switches are programmed with a manual reset, from which it would have to be reset manually or the whole HVAC system will not continue operation. This is one of many other devices that are created to keep you from harm.
Signs that the HVAC Air Pressure Switch is in Need of Replacement
- The proper temp is hardly ever fully attained.
- Incorrect voltage range reading from the switch.
- Furnace can't ignite.
