Laars Heating Systems FT1804 Sensor
The Laars Heating Systems FT1804 Sensor is a precision-engineered OEM air pressure transducer specifically designed for Mascot FT boiler systems. As a critical safety component, this boiler pressure sensor continuously monitors differential air pressure to verify proper airflow before the burner cycle initiates. By providing real-time feedback to the integrated control board, the FT1804 prevents dangerous combustion conditions and high-limit events. This HVAC pressure switch is a direct-fit replacement for Laars Mascot series units, including wall-hung and floor-mount combination boilers. Its factory-calibrated signal output eliminates the guesswork during hydronic system diagnostics, helping field technicians resolve intermittent ignition lockouts and air pressure range faults. Built with a corrosion-resistant housing, this Laars replacement part ensures long-term signal stability in high-temperature heating environments, maintaining the boiler safety interlock required for reliable residential and light commercial operation.
Key Benefits:- OEM Compatibility: Specifically engineered for seamless integration with Laars Mascot FT series control boards.
- Safety Interlock: Monitors differential air pressure to ensure safe burner operation and optimal combustion efficiency.
- Error Code Resolution: Directly addresses common E44 error codes (Air Pressure Sensor fault) in Mascot FT units.
- Technician-Ready: Factory-calibrated analog output reduces setup time and ensures accurate pressure measurement.
- Durable Build: Constructed with high-grade, heat-resistant materials to withstand demanding hydronic heating cycles.
Q: Will the FT1804 sensor clear an E44 hard lockout on my Mascot FT boiler?
A: While the FT1804 is the primary component for monitoring air pressure, an E44 code often indicates an air pressure range fault. If the sensor is failing to send a stable signal to the board, replacing it with this OEM transducer is the standard fix. However, always inspect the vent piping for blockages or cross-contamination before installation, as these external factors can also trigger pressure faults.
