Thank you for your video. I had the same issue, with one year of usage. Furnace (heat) only (no summer usage). I have a new 2022 Goodman, upflow, single-stage, 96% AFUE, 40,000 BTU/h, natural gas furnace. The repair technician purchased a "1/2 inch T hose barb (T shaped connector)" & used additional hose that came with this furnace. Then, spliced ("T"ed) into existing (nearby) drainage hose. - - - - - - - - - - Symptoms: The burners would turn on & off multiple time in one cycle. Separately, The air-flow would (also) turn on & off multiple time in one cycle. The water buildup would tell the furnace's internal computer to turn off certain segments of the heating process, but no relevant error code is thrown. Separately; After three improper shutdowns (in one heat cycle), error code EE0 (E-E-0) would display. EE0: Lockout due to excessive retries or recycles.
That white elbow pipe is still a notorious problem on the vertical upflow models. It's now a black elbow, but if the other drain outlet (this elbow has two; depending on the installation, the other should be closed off) is angled incorrectly, you will still get this issue (i.e. inducer motor filling with water). Tilt the drain spout as far downwards as you can when reinstalling, and tighten all the clamps as required.
Did a lot of Goodman installs with my 1st company I worked for. That was there preferred choice brand. Usually they always came with a rubber fernco with clamps from Goodman to connect the flue pipe out of the cabinet. They never recommend glueing the pipe because of the sch 80 to sch 40 pipe difference. We all know the flue gas/water is very acidic the joint usually ends up leaking in time. Just something i thought i saw in the video. On the other hand good find. Some techs assume that all manufacturers install the same. Fail to read manuals or don't care/ take pride in their work.
I used to be a Goodman "dealer" just because I would get tons of warranty work because the installing contractor evaporated, in the accounting world they would be called undercapitalized. These condensing furnaces were a newer thing here in Southern California a decade ago and none of the installers could get them installed correctly, especially the flue. Used to get rolls of vacuum tubing from the auto parts store and keep it on the truck, usually for these Goodman condensing furnaces.
I think that furnace installed horizontally is supposed to have a second pressure switch connected to the collector box that wires to break the gas valve. Goodman calls it a front cover switch. I could be wrong, but the few of those I’ve seen have had it. Good video dude.
Your right, and if the drain backs up that pressure switch won't close and won't fire the gas valve, you'll still get an igniter tho. It's a crappy design (imo).
I have an Goodman furnace with that litle Black plug with no hose to it. But there is 2" PVC pipe with drain nipple on side with hose going down to P-trap that is connected to condensation pump. There's another hose at Bottom of blower going to P-Trap but I see a little slot at bottom with water ring. My condensation pump works none of drain Hoses are clogged.
It looks as if the person who installed the motor unit did not care that the drain port was no longer there and just winged it. Good thing you knew what to do.
This is where Goodman gets a bad rap. 99% of Goodman Furnace problems are from crappy installation techs (like this one) who didn't read the directions on how to mounts a Upflow Furnace in a Horizontal configuration.
True, but Goodman should do a better job of explaining how to install horizontal units. They also did a terrible job of keeping the part number exactly the same even when they REMOVED the drain plug. People are buying the motor online and having major problems installing the unit. I called several Goodman engineers and they had no idea and when I found this video/answer, they were surprised how easy the fix was.
You'll be back on that one .... The 90 with the drain leg is suppose to be used in an upflow position ( which drains most the flue water ) In that position its useless .... Not having a drain in the bottom of the vent motor housing is typical gooman engineering ...
Exactly this! The drain he hooked it up to with the yellowish hose is supposed to be used if the furnace is installed in the horizontal position. Otherwise, you are supposed to use the drain at the bottom of the fan housing where it was at, yet just disconnected.
As I see it, if you have a multi-position unit the drain at the "bottom" of the impeller becomes useless depending on the application. Still, there is no excuse for improper furnace drainage.
Thank you for your video.

I have a vertical Goodman . Not sure what you mean when you say to "tilt the drain spout as far downwards as possible"?

Your right, and if the drain backs up that pressure switch won't close and won't fire the gas valve, you'll still get an igniter tho. It's a crappy design (imo).

Nice fix, if some installer's would read the installation manual, lol.
Amen to that !!
New one for me! Yay!

Condensate water may still enter into the inducer fan housing.
Was wondering the same thing, looks like the inducer housing will need to fill up to drain.
Goodman definitely has drainage issues i see it more and more
Should be called a GODDAMN furnace😝
Mine rotted my door and cabinet base

It has worked well for the last 2 winters but we will see.
