Lennox HPXA12-018 Air Pressure Switch
The primary function of the pressure switch is to see if the main blower is circulating the air as it should. Some particular air pressure switches may have a manual reset, from which the switch will have to be manually reset or the whole HVAC system will not continue operation. This switch is just one of many hardware devices made to keep you safe.
Indications of a Bad Pressure Switch
- The set temperature in the house is never attained.
- The furnace or AC refuses to operate properly.
- Incorrect volt range reading from the switch.
