It has a 45662 control ignition board.
At start up calling for heat the led flashed 2 times (System lockout failed to detect flame or sustain flame.)
After about 20 seconds the draft motor comes on, Still flashing 2 times
The rollout and limit switches are OK
Pressure switch is OK.
OK, thought it might be flame sensor, didn't help when replaced.
Changed control board, still fails with continues 2 flashes
Help
