Condensation not draining properly and causing rust in cabinet.
Unit is actually an Amana 90. It looks just like the Goodman Furnace.
Condensation is leaking out of the bottom of the black plastic cover where the ventor motor is mounted. Are the cover bolts loose? It is just a slight trickle of water, but it collects and causes rusting of the metal panels.
Is there a “proper’ fix for this? Is the furnace not level?

it could be condensation. or poor seal at roof. probably the seal at roof. also check the larger copper line is it sealed good? if any spot is not this will cause leaking when in cooling mode. maybe dripping from line onto vent.
It sound to me like your getting alot of condensation on your exhuast pipe and a weep hole was drilled to "BAND AID" the issue. These is not how 90% plus furnaces are installed. If you are referring to the outside intake and exhaust PVC piping, then there shouldn't be any weep holes. When the furnace is properly installed, the furnace comes with a condensate kit (refer to owners manual) that is mounted on the side of the furnace and all the condensation that collects overflows and should be piped directly into a floor drain. As for the intake and Exhaust for side discharge application, the Exhaust PVC pipe should come out through the side of house and immediate goose neck up (90 degree) with a straight piece of PVC pipe about 2' to 3' or so in length, then a final 90 degree PVC fitting on that so the exhaust blows out. As for the intake, that also comes out the side of the house about 2" to 3" inches parallel to the Exhaust but should only be a 90 degree PVC fitting facing down. The idea here is making sure the furnace doesn't suck in exhaust air. Also, making sure proper size pipe was used. Both outside pipes should be open to atmosphere. I hope this helps.
Hello, it's kinda diffucult to tell where the water is coming from without actually seeing it, but since you say it is coming from the bottum of the furnace it might be that the condensate pump might be clogged up or one of the hoses could be leaking that leads into the condensate pump. One other thing to check would be the humidifier, somtimes they can either leak from the drain line or the humidifier itself, check these areas out and and ask me further questions if needed.
No. The installers did not properly plumb you hose. You have a high efficientfurnace which is really nice. However, this furnace takes out moister from the air when heating, causing condensation. I would look at the installation manual and see if they installed them properly. They might of installed the wrong unit for you home. Most Goodman furnaces can only be installed up-flow meaning in the closet or horizontal installed meaning in the attic. Look at the installation manual to see if they installed the right unit for your home. www.fastacservice.com
Check the top of the gas flue. Make sure the cap is on it. If not it will allow rain to get inside. If this is only a furnace, this is the only thing it could be. Nothing produces water in a furnace. If it has an A/C coil attached. The condensation drain might be stopped up allowing it to leak.
Your furnace is more than 90% efficient and extracting so much heat from the gas that it condenses instead of blowing out steam. This is good! Figure that for every dollar you spend on fuel, you are getting back 90+ cents back in heat. Compare that to the typical units that only get 70 - 80 cents back in heat. Yes you should drain your condensate to a proper drain via gravity or a condensation pump. I would recommend you treat the condensate first with a acid neutralizer prior to draining in municipal drains due to it's high content of sulfuric acid. You can purchase these filter type neutralizers on the net or at a good heating wholesaler.
look in and around where the blower motor is located. there has to be a filter compartment there. probably near the bottom as it looks like an upflow heater. make sure the filter door is closed. it may have a door interlock switch that cuts the burner out if it is not fully closed.
