Good 12V DC power needed...check for 12V to ON/OFF switch and then to module
Bad ground connection(s)....clean/tighten
Bad connections on module board...pull connector and clean contacts with eraser
Blown fuse on module board
Thermal Cutout Bad (one time diode that is connected to normal t-stat...blows if there has been a back flame from burner tube)
Bad t-stats (normal or ECO)....connections dirty/loose/corroded or t-stats are open
And then of course.....bad module board
Need to get out a voltmeter and check for where 12V stops
Is it time for your medication or mine?
