    I have a Goodman gas furnace.
    I have a Goodman gas furnace approx 6 years old. When we turn the unit on at the thermostat the ignitor will glow red but the pilot is not coming on. I have replaced the flame sensor. Any suggestions? The LED was flashing 1 blink for possible ignitor or flame sensor but has sense quit flashing.

    Thanks!

    Check for loose wires on both the gas valve and control board. Listen to the gas valve when the glow appears and put your hand on it to hear and feel if it tries to open. If you have a multi-meter, test the leads both on the gas valve and circuit board for 24 volts AC. If no voltage you have a bad board. If you have voltage you have a bad gas valve. On occasion I have seen an igniter glow but not send enough current back to the board to open the gas valve. Although rare, it would not hurt to replace the igniter first.

    Look for a tripped roll out limit switch in series with the gas valve then push the little red button between the wires.
