Carrier 38TRA036 Air Pressure Switch
The main job of the switch is to figure out if the main blower is blowing air. Some pressure switches are designed with a reset that is manual instead of automatic, which forces the system to be reset physically in order for the HVAC system to continue running. This switch is a vital device of the safety system in place to keep you safe from injury or explosions.
Symptoms of a Rapidly Declining Pressure Switch
- Inaccurate voltage reading from the switch.
- The blower fan can not run correctly.
- The correct indoor temperature is never fully achieved.
