Description
The Carrier 347015-701 is a factory-specified air pressure switch designed as a direct OEM replacement for compatible Carrier heating and cooling equipment. Air pressure switches play a critical role in system safety, verifying that the inducer blower or combustion air fan has established proper airflow before allowing the ignition sequence to proceed. If adequate pressure is not detected, the switch interrupts the control circuit, preventing unsafe operation and protecting both the equipment and the occupants it serves.
Key Features
- OEM-specified replacement part for compatible Carrier systems
- Monitors air pressure to confirm proper inducer/combustion fan operation
- Interrupts ignition sequence if adequate airflow is not established
- Helps prevent unsafe furnace or air handler operation
- Direct drop-in replacement for simplified installation
- Built to Carrier’s quality and performance standards
Application
This air pressure switch is intended for use in Carrier furnaces, air handlers, and other HVAC equipment that require pressure-proving safety controls. Always verify compatibility with your specific unit’s model and serial number before installation. Consult the equipment’s service manual or a qualified HVAC technician to confirm proper application.
Why Replace Your Air Pressure Switch?
A faulty air pressure switch is one of the most common causes of furnace lockout and no-heat calls. Symptoms of a failed switch include the system failing to ignite, repeated error codes, or the inducer motor running without the burners lighting. Replacing a worn or defective switch with a genuine Carrier part restores proper safety sequencing and gets your system back online quickly.
