The drain holes are usually in the back corners of the pan and many do allow some water to remain in the pan to help cool the condensaer coil...

Usually the drain hole is in the back lower left of the unit.

Take some simple green spray and spray the fins on the back.

Then rinse while tilting back the unit with a garden hose.

This should get all the sludge out of it.

Condensation water does not leave pan when it gets full you can hear the water being picked up and thrown around in the unit. There is no water flowing either inside or outside unit.

What you hear is an indication that the drain hole in the drip pan is clogged. Check the outside of the bottom of the drip pan. The hole may be hard to locate, as the clog can blend in with the drain hole. It may take patience & persistence to find it. A pipe cleaner works well to clear the hole. And while you're at it, check the downward tilt of the rear of the unit. The general rule of thumb is 1/4" to 1/2" downward tilt. This will help to water to flow to the rear of the drip pan and out thru the drain hole.

Hope this helps you and thanks for choosing FixYa.

My frigidaire air conditioner is spitting water out the side and the drain hole is clear is there a secondary drain hole?

The tray that holds the condensed water from the evaporator
may be clogged, it may be clogged before the cleanout hole,
where the tray joins the pvc, if this is the case you may have to
power down your ac unit, there is a panel on your heater unit
that you will have to access to expose the evaporator coils and
you will see the tray where the condensation builds up and flows
thru a pvc pipe to go outside. also make sure that the pipe going
outside is at a slope so that the condensation can flow and not
clog the pipe. make sure that water can flow from the tray thru
the cleanout hole. once you correct the problem. you need to reseal all the seams with duct tape or metalic tape, you can purchase at most hardware stores, to make sure their are no ac
cool air leaks other than thru your ac vents. good luck!

I have a window air conditioner that is leaking water on the inside. we've have 90+ temps now for 5 days straight.

The problem you're having is usually a result of the condensation pan under the unit has a clogged drain hole. In addition, if the outer exterior of the unit is not tilted down 1/4' to 1/2", water backs up in the condensation pan and can not flow toward the drain hole.

Clearing the drain hole and being sure the unit is tilted enough, should solve the problem.

Drainage on this older system. Even at a slighty titled angle i am still having water run off inside the house. Couldn't find a weep hole either. What to do?

John, in addition to tilting the back of the unit 1/4" down, check the drain pan hole for a clog. This would cause the pan not to drain as it should.You may not see the weep hole it's clogged. It would just blend right in.

I have MODEL#MB1952HEW S 10618291GE my problem is


This would be from the defrost drain being clogged. Every few hours the defrost cycle will melt the frost from the cooling coils, the water from this cycle should flow down a drain in the bottom of the freezer, if this drain is restricted the water flows out the freezer onto the floor. See the link below for details on how to clean this out.

I have a freidrich model cp24e30 ariconditioner I just installed. Where is the drainage plug located

On the condenser / outside left rear corner about 4 incues in from the corner and left side as you look at it there is a punch out hole in the drain pan. The newer AC Units are designed to use the plastic fan blade of the condenser fan to splash water on the condenser and evaporate the water. Most of the time it is not necessary to open this drain hole unless you live in a damp climate where the home constantly has a higher internal humidity percentage. It is however necessary to have the unit serviced at regular intervals for coil and fan cleaning due to the fact that dust becomes a caked up goo over time especially on the condenser coil and the 2 fans.

If you feel that you need to open the hole in the drain pan trhen you will also need to install the 3 X 5 inch external drain catch basin with 3 screws and possibly connect an external drain hose and piping.

Thanks for using FixYa.

I have a Delonghi PAC A120LE air conditioner that leaks water. How do I stop or divert outside? I noticed there is a drain on the back - should I put a hose on that?

OK. This fixed my A120LE from leaking. First unplug the machine for safety. If you are looking at the back of the unit you need to take off the right side panel. I took off the all the panels but you could just take off the right side.
There is a reservoir on the top that collects condensation from the top coil. (shown in the circle) The drain hole on mine was clogged. If you stick a small screwdriver or paperclip in the hole to push the debris through it should start working properly again. I did this to mine yesterday and it hasn't leaked since!! Drain hole is shown here in close up picture. Unclogging this will allow the condensation to flow down to the main reservoir on the bottom where it will be evaporated in the AC exhaust.


Good luck!

The unit is over flowing even when not turned on.

If your air conditioner is overflowing with water
1. Check the drain at the base of the unit.
2. Check the drain hose post drain hole.
AC's condensate and create water and have to drain. If drain is clogged, they flood

Condensation causing water collection

Hi there!

Make sure the unit is level and not tilted forwards.Tilt back if anything.

There should be a drain hole at the back, but it may be clogged, or there may be an obstruction causing the water to build up.

In times of high humidity, water will condense on the cooling coils, and drip off. This is usually carted away by means of a tray flowing to an outside pipe.

One design uses a flinger to catch any water and throw it onto the evaporator coils - thus improving efficiency, but if there is anything touching the coils, like a feather etc, it will flow down that and leak.

Tip it back as the first action, then investigate if it doesn't drain.
