Laars Heating Systems FT1015 Switch
The Laars Heating Systems FT1015 Switch is a critical safety and operational component designed specifically for the Mascot FT series condensing boilers. As an OEM air pressure switch, this device monitors the differential pressure within the combustion chamber and venting system. It serves as a primary interlock, ensuring that the BLDC blower fan is generating sufficient airflow for safe combustion before the ignition sequence initiates. If the switch detects a blockage in the intake or exhaust flues, or a failure in the venting assembly, it will provide a signal to the GTX-920CP PCB control board to prevent or terminate operation, protecting the heat exchanger from thermal stress and preventing carbon monoxide hazards.
Constructed with a high-sensitivity internal diaphragm and a rugged housing, the FT1015 is engineered to withstand the high-cycle demands of modulating gas-condensing systems. This HVAC replacement part is essential for resolving common boiler fault codes related to airflow or pressure sensing issues. For field technicians, verifying the FT1015 pressure rating and ensuring airtight vacuum line connections are vital steps during annual maintenance or troubleshooting of FT series wall-mounted and floor-standing boilers. This factory-approved part ensures seamless integration with the existing control logic, maintaining the high-efficiency performance standards of the Laars Mascot FT line.
Key Benefits:- OEM Compatibility: Specifically engineered for a precise fit in Laars Mascot FT models including MFTCF140 and MFTCW140.
- System Protection: Acts as a safety lockout switch to prevent combustion during inadequate venting or blower failure.
- High-Precision Sensing: Features a durable diaphragm designed for accurate differential air pressure monitoring in condensing environments.
- Contractor Grade: Built to withstand the rigors of professional HVACR service and reduce callbacks by ensuring proper boiler ignition.
- What are the symptoms of a failing FT1015 air pressure switch? Common signs include the boiler failing to spark, frequent airflow fault codes, or the system cycling off shortly after the inducer motor starts.
- Can this switch be used on other Laars boiler series? This part is specifically calibrated for the Mascot FT series; always verify the MPN FT1015 against your specific model's parts list to ensure correct pressure set-points.
- Does this include the tubing for the pressure ports? This is the replacement switch assembly; it is recommended to inspect and reuse or replace the flexible silicone tubing to ensure a leak-free vacuum signal.
