DeLonghi PACT110P Air Pressure Switch
The function of the air pressure switch is to sense if the blower is circulating the air as it should. The air pressure switch is a very critical piece of the safety system in place to keep you safe from harm. The vast majority of pressure switches made today are designed with a reset that is manual instead of automatic, by which you must manually reset it before the entire HVAC system will continue operating again.
Symptoms that the System Pressure Switch is Already Failing
- Your system doesn't get to the correct indoor temperature.
- Incorrect volt running through the pressure switch.
- The blower is unable to function properly.
