Title: Goodman GMP075-4
Post by: Eto on April 20, 2013, 04:27:19 PM
It goes to ignitor enables flames, flames stay on for about 10 seconds, go out, and does this for 3 times. Any suggestions?

The control board LED might be flashing 1 flash which means flame failure.  It's most likely caused by a dirty flame sensor.

Look at the parts breakdown below, Part # 72 - Flame Sensor.  It sits behind the left hand side burner.  Disconnect the wire and use a 5/16" nut driver to remove the flame sensor and clean it with steel wool.
