Carrier 58MTA100F10120 Air Pressure Switch
The reason for the existence of the air pressure switch is to sense whether the air blower is on and running. This pressure switch is just one of many devices that are created to keep you from harm. Some particular air pressure switches are constructed with a manual reset, from which it would have to be reset manually before the system will continue its normal operation.
What to Look for when the HVAC Air Pressure Switch is on its Last Leg
- The set temperature in the house is almost never fully attained.
- Inaccurate voltage range reading.
- The blower fan is unable to run.
