Furnance lights and then burner goes out


Just replaced Ruud corsair furnace control board. Now igniter lights and burner lights but does not stay on. cleaned flame sensor but problem persists. can anything else be causing this?

I'm assuming this is a remote sensor... if so, you need to read the MicroAmps that the flame is generating. If it is anything less than 4, then either the flame is not hitting the sensor enough, or the sensor needs replaced.
