International Comfort Products H8MPL050B12A1 Air Pressure Switch
The function of an air pressure type switch is to determine whether the primary air circulator is blowing air. This switch is one of the key facets of the HVAC safety checks that are dedicated to keep you from harm. Most air pressure switches may have a reset feature that is manual, from which it would have to be reset manually before the HVAC system will continue.
What to Look Out for when the System Pressure Switch is Beginning to Fail
- The proper temperature in the house seldom fully attained.
- Incorrect voltage reading from the switch.
- The blower will not run correctly.
