Goodman ARPF30301 Air Pressure Switch
The function of the pressure switch is to sense if the main blower is running properly. The vast majority of pressure switches made today have a manual reset feature, from which it would have to be reset manually or the entire system will not run. This pressure switch is one of many other facets of the HVAC safety checks that are dedicated to keep you from harm.
Warning Signs that the Air Pressure Switch has Gone Bad
- Your furnace can't operate at all.
- Bad volt range being read from the pressure switch.
- The desired indoor temperature is almost never reached.
