    Nordyne furnace repair
    I have a Nordyne Model g5rk120c-20. The blower runs and the burners ignite. After about 3 seconds the burners go off. The cycle then repeats itself. Any thoughts?

    Clean the flame sensor with fine sand paper or steel wool.

    I have a Nordyne Furnace Model # M1MB070BW. Is it possible it doesn't have a flame sensor? We have taken it apart and don't see one on it.
