International Comfort Products PHAD36N1K1 Air Pressure Switch
The main job of the air pressure switch is to see if the air blower is doing what it is supposed to do. This switch is a very critical piece of the safety system that is in place to keep you safe from harm. The majority of pressure switches can have a manual reset, which, of course, means that it would have to be reset by hand or the whole HVAC system will not continue operation.
Signs that your HVAC Air Pressure Switch is About to Fail
- HVAC system refuses to operate.
- The correct indoor temperature is hardly ever fully achieved.
- Incorrect voltage range reading.
