Trane FLS201 Hsi Flame Sensor Angle Goodman

Product Description

The TRANE FLS201 is a hot surface ignition flame sensor designed for use in gas furnace systems. The flame sensor monitors the burner flame signal during the ignition sequence, allowing the control board to verify combustion before permitting gas flow to continue. Without a reliable flame signal, the furnace control will lock out to prevent unsafe operation. The FLS201 features an angle-mount configuration, which positions the sensor rod at the correct angle relative to the burner flame for accurate rectification signal detection. Installation is performed by licensed HVAC technicians during routine maintenance or ignition system repair.

This flame sensor is suited for residential gas furnace applications where an angled flame sensor mounting orientation is required. The raw_title references Goodman as the application context, indicating this part is positioned as a compatible replacement for Goodman-style furnace burner assemblies requiring an angled HSI flame sensor. It is typically found in single-stage and two-stage forced-air gas furnace systems installed in residential settings.

Key Features

• Angle-mount design positions the sensor rod correctly relative to the burner flame
• Hot surface ignition compatible flame sensing for accurate rectification signal
• Designed as a replacement flame sensor for gas furnace ignition systems
• Supports control board lockout protection by delivering consistent flame signal output
• Direct replacement form factor for Goodman-application angled flame sensors

Compatibility

Designed as an OEM-style replacement angled HSI flame sensor for residential gas furnace systems requiring an angle-mount flame sensor configuration, with application context referenced for Goodman-style furnace burner assemblies.

Installation Notes

Flame sensor replacement is performed by a licensed HVAC technician. Shut off power to the furnace at the disconnect and turn off the gas supply before beginning work. The sensor rod must not be touched with bare hands, as skin oils can degrade the rectification signal and cause nuisance lockouts. Refer to the furnace manufacturer service manual for torque and mounting specifications applicable to the specific unit being serviced.
