Question about Goodman GMS90703BXA Heater
Heat caused damage...simple to understand here! The heat exchanger has been compromised at one time and the drain pan was designed for the AC in this case and not a combination Heat an AC. I would add that the rudeness of this person is completely consistant with there question. It is Chewed up! You want better answers then ask better questions. You want anything more then what I read for solutions then it is time for you to reach for your billfold because your free nickels worth is over!

Neither maker is at fault if the units were simply placed too close together.
Anyone should already assume it would be wrong to place an AC unit directly on top of a furnace unit, unless the makers were so foolish as to claim you can.

Hi, I have read through all of the questions and answers. So here is what I have to say about the mess. Normally the condensation pan is made of sheet metal to catch the moisture and has a 3/4" adapter for it to drain through the condensate line, but they went with a high grade of plastic, nothing wrong with this as I have replaced more of the sheet metal trays by making them, because of rusting out pans! The evaporator coil sets on top of the furnace with the pan, completely separate from the furnace, for cooling only. Your pan was cracked 2 years ago and was only repaired with whatever! The tech should have addressed the problem as apparently, your burners are putting out to much heat in that area to cause this. It is simple. When this furnace was installed, we do what all companies are ( supposed ) to do, a start up on both heating and cooling. Now, when doing a heating start up, the inlet gas pressure must not exceed 1/2 p.s.i. !!! Outlet or manifold pressure must not exceed the gas vale rating which would be 3.4" of water column. Apparently, the manifold pressure was not set properly, and the TD was not checked to see what the unit was putting out. Now, if all of the things I have just said were checked and were with in spec's, there was a failure somewhere in the furnace, not the A/C, a plugged or crack in the heat exchanger, a internal problem with the gas valve, and even a problem with the Gas Companies meter! The flue pipe restricted, maybe a bird nested in it during the summer, believe me it happens. The furnace should bare the responsibility for the failure of the condensate pan. This furnace needs to be checked, heat exchanger, burner flames, inlet and outlet/manifold pressure. TD of the return and supply air in the heating mode. I have had to plug off a burner on a brand new 5 ton Bryant unit due to the fact that the unit was sized right, but, the TD was off the charts and the return air would trip the klixon limit in the blower compartment! This was a new R-410a/gas roof pack unit. This solved the problem. You do have a furnace problem, who to blame, don't know! Blame somethings not right with the furnace as it caused the pan to melt, warp, crack, and leak. It needs a good going over to find out why that one area was hotter which like I said could be a number of things. You can have a sheet metal condensate pan made with the 3/4" male or female adapter on it at a sheet metal shop for around $25.00 to $30.00. First solve the to much heat problem. Heat rises, and it the heat gases are not expelled from the unit through the flue with the help of the inducer or combustion motor, it will rise and start to do damage above and beyond. I hope I have been of help to you on this. We do have some awesome techs here on Fixya, and it can be difficult to troubleshoot a unit on line. I have been in the field for 33 years and I am still out there, 24/7 if my business needs me. I wish you the best.

You would need to look at the warrenty of the product from the manufacturer of this whole unit. If they were purchased as individual parts then each manufacturer is responsible for their compinents.
However, you must have a warrenty on the product to be able to bear any responsibilty to the manufacturer.
If you do have a warrenty then they should up hold it, and they should also have a solution to the fault. It will be pointless to replace the tray only to have it reoccur again. It seems as though they have missed out putting a insulation of some sort between the heat source which evaporates the water in the tray.
Hope this helps, let me know how you get on.

The water that flow on the floor is generated from the A/C because the Furnace do not generate water during and after functioning it only generate heat what brings (generate) out water during and after his function the A/C
what an furnace means is an enclosure in which energy in a nonthermal form is converted to heat, especially such an enclosure in which heat is generated by the combustion
the water is from the A/C.
Thank you and thanks for using fixya.

The AC drain tray should be made of metal of course Blame it on the engineer who designed this & the QC managers for ACCEPTING THIS toy like part stuffed into your furnace

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.

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.

I have a forced air gas furnace and water is leaking from just above the area where the hose is attached. I removed the cover but cannot figure this out. It only leaks (a lot of water) when the furnace is running. Please help asap!!! Tthanks so much, Dianne
