Keep your Nordyne FG6RC 080C-16B downflow gas furnace running dependably with genuine OEM replacement parts from Repair Clinic. The FG6RC 080C-16B is an 80,000 BTU downflow gas furnace designed for manufactured and mobile home installations under HUD standards; the 080C-16B designation indicates 80,000 BTU input capacity in a 16-inch wide cabinet. The KG6RC 080C-16B is the same furnace under a different Nordyne brand channel designation with fully interchangeable service parts. In the downflow orientation the FG6RC 080C-16B delivers heated air downward into the subfloor duct system, with the burner box at the top of the cabinet and the inducer drawing combustion gases upward before exhausting them. Parts most frequently replaced include the hot surface igniter, flame sensor, control board, draft inducer motor, and pressure switch. Browse the full Nordyne furnace parts catalog.
FG6RC 080C-16B: Downflow Platform Service Differs from Upflow Furnace Work
In the FG6RC 080C-16B downflow configuration, moisture from combustion gases accumulates near the inducer housing more readily than in upflow installations, accelerating bearing wear. Pressure switch hose routing runs through a confined space in the downflow cabinet that is prone to kinking when insulation is displaced during service. The control board is programmed for the downflow orientation and must not be substituted with an upflow Nordyne board. The FG6RC 060C-12A is the smaller sibling at 60,000 BTU; the pressure switch and inducer from the 060C must not be substituted into the 080C-16B installation.

Most Replaced Parts on the Nordyne FG6RC 080C-16B
FG6RC 080C-16B Hot Surface Igniter
The igniter is positioned in the burner box at the top of the downflow cabinet, accessible after removing the upper access panel with power and gas disconnected. The silicon nitride igniter on this platform should test between 40 and 90 ohms at room temperature; an infinite resistance reading confirms an open-circuit failure. Browse Nordyne furnace igniter parts.
FG6RC 080C-16B Flame Sensor
A furnace that lights and shuts off within two to five seconds of ignition, repeating until lockout, is showing the flame sensor symptom with high specificity. Annual light cleaning with fine steel wool is the most cost-effective preventive maintenance step. Browse Nordyne furnace flame sensor parts.
FG6RC 080C-16B Control Board
The control board sequences the downflow blower and ignition timing specific to this model and must not be substituted with a board from an upflow Nordyne model. Read and document the LED blink code before ordering any replacement; a board that generates the same fault code repeatedly after all components have tested good is a strong indicator of board failure. Browse Nordyne furnace control board parts.
Draft Inducer Motor for the FG6RC 080C-16B
In the downflow orientation the inducer draws combustion gases upward through the heat exchanger. Moisture condensation near the inducer housing is chronic in this orientation and accelerates bearing wear; an inducer that grinds at startup should be replaced proactively before complete bearing seizure means no heat until the part arrives. Browse Nordyne furnace inducer motor parts.
FG6RC 080C-16B Pressure Switch
The pressure switch is calibrated for the 80,000 BTU downflow heat exchanger draft; it must not be substituted with a switch from the FG6RC 060C-12A, which has a lower trip point. Inspecting the pressure hose for kinks behind displaced insulation is the first diagnostic step before replacing a switch showing a fault code.

Nordyne FG6RC 080C-16B Furnace Parts FAQ
Are the Nordyne FG6RC 080C-16B and KG6RC 080C-16B the same furnace?
Yes. The FG6RC and KG6RC share the same downflow manufactured home platform; the prefix indicates the brand channel through which the furnace was originally sold, not a fundamental engineering difference. Service parts are fully interchangeable between both designations.
How do I access the igniter in the Nordyne FG6RC 080C-16B?
In the downflow configuration the burner box is at the top of the cabinet. Remove the upper access panel to expose the burner compartment after disconnecting power and turning off the gas supply at the shut-off valve. The igniter is positioned in the burner flame path and should be tested for resistance before removal confirms an open-circuit failure.
Why does the FG6RC 080C-16B inducer grind at startup?
Grinding at inducer startup on the FG6RC downflow platform is almost always bearing failure caused by moisture condensation in the inducer housing in this orientation. Replace the complete inducer assembly rather than attempting to service the bearing alone; a seized inducer prevents the pressure switch from closing and shuts down the furnace entirely.
What is the difference between the FG6RC 080C-16B and FG6RA 096C-16B?
The FG6RC series tops out at 80,000 BTU with the 080C model. The FG6RA series includes the higher-output 096C-16B at 96,000 BTU. The inducer motor and pressure switch specifications differ between these output classes and must not be cross-substituted; a 096C pressure switch installed in an 080C installation has different trip points that affect draft verification.
