Carrier 48XZ030060300TP Air Pressure Switch
The main job of the air pressure switch is to see if the main blower is blowing air. Most air pressure switches are constructed with a manual reset, which forces the system to be reset physically or the whole HVAC system will not continue operation. This is just one of many safety creations designed to keep everyone in the house safe.
Symptoms to Look for when the HVAC Air Pressure Switch is Beginning to Fail
- HVAC system can not run.
- The desired temp seldom achieved.
- Incorrect volt being read.
