Carrier 58MTA100 Air Pressure Switch
The main job of the air pressure switch is to figure out if the blower is blowing air. This switch is part of all the safety features in today's HVAC systems in place to keep you safe from harm. Some pressure switches are programmed with a manual reset, by which you must manually reset it or the entire system will not run.
How to Know when the Switch is Starting to Go Bad
- Inaccurate volt range being read.
- The set indoor temperature is hardly ever fully achieved.
- Your heating and cooling system will not run.
