Luxaire error 7 flashes


Trouble again on my Luxaire g8t08012dna11a

It cycles 4 times by igniting and flames are present then again shuts down cycles to flame then after 4 or 5 trys it locks down with 7 flashes. But this error says no ignite??? If I play with this a few times I can get heat. But later on it fails again. I will take the cover off and that cuts power to the board and will do this again. I have fixed this unit twice before with your help and hoping I can get this going. I am very handy with electrical testers and such. Thanks guys for any help. Rick

clean the flame sensor with steel wool or fine emory paper 400 grade or higher. should look like one of these. it cannot get a signal and thinks there is no flame. also clean the face of the burner it sits in front of or the fire wall in front of the sensor. it is sending a signal/current thru the flame to the burner or the wall and that conducts back to the board thru grounding. no flame no signal or it is so weak the board cannot read it.
