We found parts lists for older Goodman GU-series heaters - now available above on this page, but I've not found the IO manual for the GUE040 heater - I'll continue to look and post whatever we can find here.

The Goodman website doesn't have any information about my much older model, GUE040-3. Does anyone have any info (esp manuals!) about this furnace model?
