International Comfort Products HHP042AKA1 Air Pressure Switch
The function of the air pressure switch is to sense whether the main blower is running properly. This is one of the critical devices designed to keep you from harm. Some different switches are designed with a reset that is manual instead of automatic, which makes you reset it by hand before you can continue using the system.
Signs to Look Out for when your Air Pressure Switch is Beginning to Go Bad
- The furnace won't operate.
- The right indoor temperature is almost never achieved.
- Wrong voltage range being read.
