I wire the module up correctly and have 24V to module but no spark or led fault lights. The exhaust fan starts up and ignition sequence starts but no spark. Suggestions or exsperience with this module. Thks Mike

Could be a dead modual on the spark end of the device. OR you migh check for proper grounding. Loosen grounds and retighten to make sure of good contact.

Do you have 24v from TH to Common on the ignition box? If not check all limits-- vent limit,rollout limit,main limit and so on. Make sure the pressure switch is closing after the inducer motor starts.
