Goodman GPH1448H41AB Air Pressure Switch
The reason for the existence of the air pressure switch is to figure out if the primary blower is circulating the air as it should. Some pressure switches are equipped with a manual reset feature, from which it would have to be reset manually before the HVAC system will continue. This is one of the vitally important safety devices designed to keep you safe.
Clues that your Switch is Beginning to Fail
- The expected temperature is hardly ever attained.
