Where can I find a Goodman gmp 100 3 manual. Just moved into a new house with an older furnace and got hit with a $600 bill to replace a gas regulator, only to find that it is a $100 part(at best) and 45 min. process. I was told that the inductor fans are a big problem on these units and when that fails it'll be another $500, the ignitor is $150 for replacement and that's if they don't require another service call(fix it RIGHT now while I'm here). I found these parts for $120 and $39, respectively, and for simply fixes, as these, I'd rather do them myself, but need the part numbers on the parts involved. Any help would be greatly appreciated.

Most sources will allow you to order the parts by model number since the part numbers change every few years...
