LAARS-RW2014901 Flame Sensor Magnatherm Boiler

Product Description

The LAARS-RW2014901 is a flame sensor designed for use in the Laars Magnatherm Boiler 2000-4000 series. The flame sensor monitors the presence of a burner flame and sends a signal to the control board to confirm ignition. If flame is not detected within the trial-for-ignition period, the control locks out and shuts down the burner as a safety measure. Licensed HVAC technicians and hydronic heating specialists are the primary installers of this component.

This flame sensor is applied in hydronic heating systems using the Laars Magnatherm Boiler 2000-4000. It is suited for commercial and residential boiler installations where reliable flame detection is required for safe burner operation. Replacing a failed or degraded flame sensor restores proper ignition-sequence function and prevents nuisance lockouts caused by false no-flame signals.
