Where is the main overflow pipe on my goodman furnace ac model number A24/10

Is this a new tstat? How about trying cooling with fan in on position , what happens? What is the model number of your indoor unit please.

If you need further help, reach me via phone at https://www.6ya.com/expert/thomas_092728000e6acb79

In most cases, they do not come with a overflow valve, That is a addon that most companies install when they do the install. They can be purchased from most ac suppliers I recommend the SS-2 or SS-1 safety overflow switch, comes with two wires you can tie into your low voltage wiring to your thermostat.

Hope this helps.

the best way is to contact Goodman and ask them for the model, in base from the detail that you have. If you have some wiring diagram or instruc. manual you can identify it. if you do not have downloa give your model +mark+serial number and proceed:

Hello Jmranes,
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.

Try this one.

Adhiinc, the model you posted is for an AC coil made by Goodman. You will need to post the Make and Model number for the air handler/furnace that this is connected too. You can find the model number if you remove the front panel and look on one of the sides for a label. Thanks and good luck!

the clear plastic hose is the condensate drain .. indeed they clog frequently .. lthat will allow water to overflow the pan that is desined to capture condensed water from the evaporator.. the plastic hose and the pipe it is attached to need to be cleaned out periodically ... allowing water to overflow can damage other things so its important to get the drain cleared .. however that drain has little to do with cooling efficiency .. your lack of cooling performance could be another problem ... sometimes the evaporator coil gets clogged (large finned unit behind where the overflow hose is attached inside furnace) .. that has to be cleaned once in a while but is tricky to do ... how often depends on how good the furnace air filter is and how often its changed ... as the evaporator becomes clogged with dust the cooling efficiency goes down .. same with the outdoor unit ... you have to wash out leaves and such periodically from the condenser coils .... if every thing is clean but the cooling efficiency is still low then have the unit checked for refrigerrant pressure .. it could be low .. of course make sure the furnace filter is not clogged ... also for cooling make sure all of the registers are open ... closing some can reduce overall efficiency ... make sure the outdoor unit fan is working properly ..

from my experience with goodman units ,it could have been a gas supply problem there are so many protective sensors that i dont think it is the unit by the way is it electronic ignitor or pilot

One of the drain tubes (overflow) is plugged. Unhook each one and clear them of any debris.

I don't know where you are located, but there is a Goodman distributor in Sacramento, CA. Also in Ontario CA. They are a distributor so they may be able to help you or tell where to find someone who will help. Goodman is also known as GMC or Janitrol.
