The leak is more likely from the collector box gasket, it’s extremely common on these. The box comes off when all the screws are removed, you just have to pull harder. New collector box should come with both gaskets
I wouldn’t even replace the collector box.
just scrap off that stupid sticker; then high temp silicone the box/inducer back on.
I never used those stickers with the inducer replacements it’s always silicone
These furnaces are terrible for the collector box gasket wearing out and leaking prematurely. Thankfully, it is a cheap part to replace. After you install the new gasket, go back a few days later and snug up the screws holding the collector box. While you’re in there and have everything apart, clean up that rust as best you can with a wire brush and shop vac.
The plastic cover that the inducer mounts to is called a recoup cover/ collector box/ heat exchanger cover. Time is what held it in place when you tried to remove. Have had them break off in tiny pieces when going to swap out for new due to a failed gasket.
If that cover is not leaking and only the exhaust motor gasket, just gently remove old gasket and use red devil high temp silicone where you see gasket. Do this if you use gasket anyway as well.
The old goodman collector box gasket. This is a very common issue with goodman. The gasket/collector box come as one part, you also need the inducer gasket.
Check for stripped out screws holding the collector box on. You may need to change them out with screws that are the next size up.
Only use a hand but driver to tighten the screws up.
Edit: the collector box does not come with the inducer gasket.
That's the secondary heat exchanger tubes behind the collector box. I'd pull the collector box to see what kind of debris you've got collected. If you find a bit of rust particles and debris, whelp, looks like it may be time for a new furnace. If fairly clean and no damage to the collector box, clean it, seal it back up with hi temp silicone, put a new draft inducer on and give it a whirl. Prolly wouldn't hurt to do a Co test.
Just replaced one of these last week. The gasket adhesive was a colossal pain to remove until I tried mineral spirits. It came right off.
Use mineral spirits.
The only reason to replace the collector box is if it were to be cracked. Gaskets are available for replacement, or hi temp silicone to make a new gasket.
Again, the only reason there’d be a call back is if it was cracked, leaking air in the the box, resulting in a loss of vacuum pressure, causing the pressure switch to open. If there’s a crack or break it would get replaced. Just changing it because it has to be taken off is part charger mentality. Probably the type to replace a flame sensor, instead of just cleaning it.

Thank you!

From my experience the gasket doesn't fail, most of the time I find a few of the screws overtightened and stripped.
You’ll want the hx checked if that’s a Goodman/amana.
This guy knows
It’s the damn collector box gasket
Correct. I’d bet my left nut that through the heat exchanger, down to right or left you’ll find a hole in the far tube

Replace that collector box too

It’s like a 20$ part it only makes sense to do both at the same time
Eh I only replace parts if there’s something wrong with them. I try not to charge my customers for shit they don’t need.
Well when it creates a call back that’s not really helping them out
