I have a cracked condensation pan under my coil in my goodman furnace which is less than 10 years old. We cannot run out air without filling the basement with water puddles. What do I do?

The problem is too much gas as opposed to not enough air. It is still running rich. Did you take into account the elevation of the location your furnace is installed at. The higher above sea level the less air that you have to aid in cumbustion. The condensation is from excess gas being cold and causing water to accumulate. Can you run it like this? Yes but it will cause issues with soot and carbon deposits. It will also cost you more money in the long run.

The drip pan sets under the indoor coil, not on top. The numbers wold be found inside the coil's cabinnet

Hello, it sounds like your condensate line is clogged and not be able to drain into the condensate pump or your condensate pan is cracked and leaking. Best thing to do is clean the condensate line with a shop vac and see if the water will start to drain, if not looks like the pan is cracked.

There is a drip pan bit the middle is open to allow air flow through the coil and into your ducting. If the drain for the drip pan is clogged it will fill up and overflow onto your furnace and then to the floor.If that is what is happening then clean out the drain tube running down the front of the furnace and it should empty the drip pan and solve your problem.

You also need to have your furnace checked for water damage in the electrical components, if these have gotten wet then you run the risk of a fire. Please consider calling an expert in your area to inspect your furnace and make sure the drain line is clear.

If the drip pan switch is shutting the unit down , this means you have a condensate drain issue. Be careful about wiring around any safety switch, especially if the furnace is in the attic or on a second floor. You could have water dripping on the ceiling. The drip pan switch is a safety switch. The best thing to do would be to inspect the furnace. The pan is underneath it. Look inside the pan if you can. If it is full of water, use a shop vac and vac the water out of the pan. If there is no water, you can locate the safety switch, take the two wires loose from it and just wire them together. Caution: This will be wiring around the condensate safety switch that could cause water to leak on the ceiling or floor depending where the furnace is. Don't go too long without getting someone out to clean the condensate drain out.

Hi, what has happened, is the condensation pan under the evaporator coil that sets on top of your furnace, has rusted out and is running down to the wooden floor it sets on, or what ever flooring you have. To be honest, this is quite a job to do, as the coil that is over it, the a-coil will need to be removed from the system to get to the pan. The condenser has to be pumped down pulling all of the freon from this coil to the outdoor coil, and closed off to contain the freon. Then this indoor coil will have to be cut at the inlet and outlet lines to remove it. Then there is excess to the pan. I have always taken the pan into the sheet metal shop and had a new one made along with the 3/4" condensate drain fitting. You can try removing as much metal as you can. and use tin snips to cut around the lines to remove the front. You can then see the pan, and the condition. Check the pan and condensate line to see if maybe it is just plugged up and running over. That would be great if that was the only problem. I would either try and use compressed air to blow out the line, or see if you can get a hose and water into it. That would be the first thing I would try. If not, take as much of the front off as you can. If you have to make cuts, you can buy aluminum a/c tape to seal around any pieces you had to remove. Then you can gently raise the coil so you can remove the pan without having to cut into the copper. If it is rusted out, take it to any Heating and air conditioning shop that does sheet metal work, and they will make you one for around $30. Well worth it. This is your only options unless you spend the $$$$ to have them come out to do this. They will cut into the freon lines and pump it down to do the job. Very costly. Please keep me posted and updated. Contact me for anything you need to know.

PS, After you blow out the pvc line, go around the house where it drains to see how much gunk has come out. Hopefully, that's all it is. Please don't forget to rate me on this! I know you will be kind. :))

insulate and seal

Buy a new pan. Once they are broken they cannot be sealed due to the fact that they will not level out and will have problems with water going in other directions then to the train pipes

This is not a lot to go on.

I assume since you called it a furnace, you have hot air heat and central air conditioning. If so, the only way a furnace/AC unit can generate water is by condensing moisture from the air. This is common to all air conditioning and removes humidity from your home. If so, this water, called condensate, must drain. The condensate is collected at the AC cooling coil that is typically located on top of a vertical upflow furnace or downstream of a horizontal furnace. If the drain is clogged, it will overflow and create a mess in and around the furnace. If this is your problem, cleaning and clearing debris may solve the issue. I suggest starting with the easiest accessable part of the drain path. You may need to open the panels enclosing the AC coil and clean the small pans at the bottom of the coil and clear openings from above that look similar to a laundry tub drain. If you get that far and find rust holes in the pan, repairs are needed. If you have an electric condensate pump that may also be the cuprit and require cleaning. Check and clear all drain lines from the coil connection to the final dicharge - sump pit or outside.

This may be caused by an un level unit, or the A-coil itself may be un level did you move it when you replaced the fan motor? The second thing to check is the fitting at the condensate drain pan to make sure the weld has not broken or the fitting has not been stressed or bent and have a small crack.

Hope this helps Ya
