Hello, did you clear or replace the flame sensor rod when you replaced the ignition module? Is the flame present before it shuts off, or do you get no ignition at all?
Thanks, ***** ***** model number however I can't tell what sort of ignition it has,
A wiring diagram should be glued to the inside of the blower access panel, if you can take a well lit, close up and exceedingly well focused photo of it I might be able tell what kind if igniter and flame sensor it has. Usually however the flame sensing is via 3 inch long rod, and the ignition is either sparking rods, OR a glow plug type igniter,
attach the photo using the attach files link to the left of your send button, we can go from there.
Thanks, the wiring diagram is a bit too faded for me to tell exactly what you have there.
So far it sounds like bad sparking rods if its a spark ignition (you can clean and re-gap them) OR a bad glow plug ignition,
IF it is a sparking rod ignition there will be a very thick wire running from the ignition module to it, almost the size of a lead pencil.... if its a glow plug ignition there will be two smaller size wires running to it, (not including the wire that runs to the flame sensor)
click here of for pictures, let me know what you can discover, we can go from there
Yes changing the ignitor and flame sensor has a good chance of fixing the problem, 90% or so.
without a furnace model number however that could be a problem.
Maybe, however if you can remove the old igniter assembly and take some pictures of it, that would work and you could read the voltage right off of the igniter if its a glow plate type
Good idea. I am off to bed now, let me know if you have any problems with it tomorrow,
