Nordyne P3RA-048K Air Pressure Switch
The reason for the existence of the switch is to sense whether the main blower is blowing air. This pressure switch is a very critical piece of the collection of safety devices in place to keep you safe from injury or explosions. The majority of pressure switches have a manual reset feature, which forces the system to be reset physically or the whole HVAC system will not continue operation.
Symptoms to Look for when the Switch is Starting to Fail
- Wrong volt range being read from the pressure switch.
- Furnace won't operate at all.
- Your system doesn't actually get to the right temp.
