Plasmaire unit not draining into pan and leaking water into room. Both units have done this. One the pan overflowed and we drilled a hole to release the water but shortly after the unit stopped working. The other, the water isn't even making it into the pan?

By all means. That water should not really be collecting there - it can eventually overflow and wind up in the room being cooled. And if you want to be fancy you can insert into the hole some clear tubing you get from Home Depot with an OD a tad larger than the hole you drilled and direct the flow of evaporator water via gravity to where ever.

dont drill a hole window units use the water to help cool the condensor.

It appears that the drain is plugged it sounds as if you have it tilted enough . U should be able to remove the front cover from the unit and see the drain behind the evaperator between the inddor fan motor and the evapator. you will see a pan might be plastic under the evaperator . look for the drain . they are sometime difficult to find but it's there. be certain it is open. You might also (if it has a drain hose Blow a bit of air up against it and clear it as well. either way take a bit of of house hold cleaner and drop in the drain pan .. this will help a little to clear the drain . Let me know hope this helps

Part of the problem may be, that you don't maintain enough tilt down on the back of the unit. 1/4" to 1/2" is generally enough to drain the water to the rear of the drain pan. Some drain pans have a hole near the rear of the drain pan. They can be hard to find, if they're clogged, because the clog blends in with the drain pan. Others may have a **** in the corner of the drain pan, rather that a hole.

If you are unable to find the drain hole to unclog it and you're feeling really lucky, you can always drill a 1/8" hole in the rear corner of the pan and create a new one. However, the unit must be unplugged and the pan must be almost dry, before attempting this. In addition, you must be extremely careful when drilling this hole, so as not to pierce any of the mechanical parts above it. In other words, you must be in total control of the drill.

Hope this helps you troubleshoot and solve the problem.

Mellisia, the problem very well may be, that the drain pan hole under the unit, on the outside may be clogged. When that happens, water backs up and leaks out the front of the unit.The drain hole should be near one of the corners of the drain pan. And with Fedders, it may be on the edge/lip of the drain pan. The clog, may appear to be part of the drain pan and that's why you haven't noticed it.

Inspect the drain pan closely. If you can't find it. You can create one, by CAREFULLY drilling a hole at one of the corners of the drain pan. It doesn't have to be a large hole 1/8" to 1/4" should do.Be sure the unit is OFF and unplugged from the wall, before attempting this. Also, once the drill bit penetrates the drain pan STOP. You don''t want the drill bit to pierce the coils on the back of the unit.

Hope this helped you. Please let me know. Thanks.

These are designed to retain some water in the pan. This is for the slinger fan to throw water through the condensing coil. This helps the refrigerant cool and is important to the efficiency of the unit. I would certainly not recommend drilling a hole in the bottom. The hole may cause the water to roll somewhere where damage could occur. Try instead tipping the unit Backwards before bringing it in the house.

It sounds like to me that the leak is coming from inside the unit(air handler) possibly your evaporator coil is icing up and causing a build up of water just below where the 3/4" P.V.C. drain line connects. Instead of draining out the line, it is finding its way out of the unit else where. I have seen this many times. It sounds like you have done everything that I would have done, but take a look at the bottom of the evaporator pan and I bet that it also is starting to rust out.If the new overflow pan is not leaking, and the condensate line is leak free, it has to be leaking from the evap pan inside the unit.That's why you have the overflow pan in the 1st place to prevent ceiling damage as I am sure you know. I hope I have been of some help to you, please let me know what you find.

your drain hole on the ouside of your unit is plugged up, I always drill a couple extra 1/4" holes on the outside on the bottom to prevent that from happening, take caution when and if you drill your own extra drain holes not to go to deep and damage internal parts.

It's probably just holding water somewhere and getting thrown out. I've seen people drill holes on the bottoms to drain water quicker.

To increase the efficiency of the air conditioner's cooling to meet US energy requirements, most manufacturers eliminated the traditional drain plug. Instead, they switched to a design that used the extracted moisture from the room to help evaporatively cool the condenser.

To do this, the traditional fan blade was replaced with a 'sling blade' which was a fan blade with a rim or ring around it. The drain plug or drain hole in the bottom of the pan was eliminated and replaced with overflow notches in the back edge. Along with a solid piece drain pan, this provided a pool of water for the edge of the sling blade to dip into and pick up water to 'sling' or spray around the compartment to create evaporative cooling. The overflow notches established the maximum depth of the water pool and are also the lowest place when installed properly.

Although this is more efficient, this has caused 2 problems: increased noise as the water is slung around and water spray from the side air vents.

Persons have drilled holes through the pan or back edge as drains. This is not recommended as it negatively effects the colling ability of the unit and could lead to a voided warranty or premature failure.

Instead, insure that there is adequate pitch with the installation and make sure the overflow notches are kept clear.

If you 'need' a drain hose, my suggestion would be to drill into drain pan's back edge or the rear potions of the sides. The hole should be at the same level as the overflow notches. Once the drain hose is installed, block/cover the overflow notches to redirect the excess water to the drain hose instead.
