Armstrong G1n80 Furnace Manual
Please help us! If you have a manual for your furnace, please reply to this thread with the following info: make and full model of your furnace (from your nameplate), list of all codes and their meanings (please type this word for word), and somewhere in your manual it will list the models or series that your manual is for. I need this too. Ideally, I would rather see a picture of the section of the manual with the codes. You can also take a picture of the troubleshooting guide that is often on one of the covers. This will help with typo's. If you know of a link to your (or any) manual, please post it!
