Frigidedare furnace ONE single burner (out of 4) is sputtering after ignition. I’m not a tech but very handy and mechanical.

    Dirt in the orifice that feeds the burner
    Insufficient pressure
    Too much air
    These are the first 3 things I might check

    Do you have a pressure gauge (manometer) for checking gas pressure?

    Is it an end burner or a middle burner?
    Is it propane of natural gan?

    Finally, If this is not your profession... Have you had a professional maintenance performed on your equipment?

    Some people do their own oil change and maintenance, some take their Ford to a dealer. Heaters need maintenance too!
    Have you ever asked for an air filter for a Ford? The first question the counter man will ask is " Model and Year of the car?" so... your Frigidedare... How old and does it have a model number?

    A picture of the heater and of the problem burner can be very helpful too

    In addition to the above the burner could be dirty or twisted out of alignment
