International Comfort Products PYMC30G5 Air Pressure Switch
The job of the air pressure switch is to sense whether the blower is blowing air. This switch is part of a small, but important collection of facets of the HVAC safety checks that are dedicated to keep you from harm. The vast majority of pressure switches made today may have a reset feature that is manual, from which the switch will have to be manually reset before you can continue using the system.
Signs to Look for when the Switch is in Need of Replacement
- The blower fan can not function.
- The expected indoor temperature is rarely fully attained.
- Incorrect voltage being read.
