International Comfort Products T9MPD080J16B1 Air Pressure Switch
The job of the air pressure switch is to determine whether or not the blower fan is blowing air. This pressure switch is just one of many safety creations designed to keep you safe. Some different switches may have a reset feature that is manual, which forces the system to be reset physically in order for the HVAC system to continue running.
What to Look Out for when your Pressure Switch is About to Fail
- The blower fan can not run correctly.
- Wrong volt range being read from the pressure switch.
- The right temp is hardly ever reached.
