Payne PA1ZNA036000AAAA Air Pressure Switch
The function of the switch is to determine whether or not the main blower is doing what it is supposed to do. A good number of pressure switches today are constructed with a manual reset, which means it would need to be reset or the entire system will not run. The air pressure switch is a very critical piece of all the safety features in today's HVAC systems in place to keep you safe and keep your family safe.
What to Look Out for when the HVAC Air Pressure Switch is Starting to Fail
- Incorrect electrical voltage being read from the pressure switch.
- The set indoor temperature is hardly ever fully attained.
- Your heating and cooling system can not function.
