Air conditioner is leaking but lights not blinking

Upper drip pan drains clogged, water overflowing onto the floor.

Remove the rear cover of the unit and clean it thoroughly wit a vacuum. Let the unit fully defrost. Use a can of Air duster (for pc's) with the little hose on to clear the drain holes in the upper drip tray. Clean dirty evaporator fins with windex and toothbrush, flush with water. Excess condensate should now drain into the bottom tank instead of overflowing ontot he ground. Be sure to drain the bottom tank thoroughly. With the unit cleaned it should now vent condensate out the warm air duct rather than letting it build up in the unit.

What kind of leak? Is it a clear liquid like water condinsation coming from the air conditioner?
Or is it grean or reddish like antifreeze? Is your water temp. lite coming on or gauge running hot?
Is it a dark thick liquid like oil or transmission fluid? Have you checked your oil level?
Tell us more about the leak, what does the fluid look like? Is it a lot like a puddle or little drips?
Need as much information as possible
Thanks

First, have you drained the tank recently. If not, the warning light or auto shutoff failed and the tank may be overflowing. Worse case scenario is the that the tank is dirty and is not allowing the coils to cool and the dripping water you see is from the cooling coils. Since the tank is not removable, it's very difficult, at best to clean the tank.

If you drain the tank and before reinserting the drain plug, try to get about 1/2 teaspoon of bleach in the drain hole. followed by 2 cups of water. Of course you'll have to use a funnel of sort to do this. Reinstall the drain plug and move the unit around so the water and bleach will slosh around. Then run the unit until the bucket is near full again and drain it thoroughly. Look at the color of water draining out, for an indication that there is dirty water. That will be a good indication, that some cleaning of the tank has taken place.

Hope this helped you and thanks for choosing FixYa.

Hello
Check that all the drip trays are in place and not out of place and that there are no holes in any pipes
Thanks

If its' tank is full of water then empty it. If it is not full of water then the switch underneath the tank may be faulty

Probably needs cleaning. I assume it is on a level surface. Water drips from the evaporator coil into a collection tray of some type and then drains into the holding tank, this tray is either broken or the outlet is plugged.
Good Luck,

It sound like the coil inside could be dirty. I have had the same problem with air handlers, when the coil is dirty or the filter is dirty it creates a back pressure and causes the condensation to drip off away from the condensation pan. Try accessing the coil on the inside see if it is dirty, if it is clean it lightly with soapy water and a brush and be carefull not to bend the fins on the coil. If it is clean double check the condensation hose and inlet for the hose for foreign matter.

We have a 1-year PE3-09R-03 that just started dripping water on the floor. The red "tank full" light never came on. I opened it up to investigate, and I believe the problems are caused by dust. The plastic float that trips the "tank full" switch appears to have gotten stuck due to the combination of water and dust in the tray. Once I loosened it up and cleaned the guide tube it rides in, it would trip the switch when the tank was full. The reason the tank was filling up was a little less obvious. There is a 2-piece plastic tray that sits underneath the evaporator and above the condenser. The tray is supposed to distribute the water that's dripping from the cold evaporator coils onto the warm condenser coils so it can evaporate and be blown out with the warm exhaust air (note that "evaporator" and "condenser" are referring to the refrigerant - the terms appear backwards when referring to what's happening to the water on the outside). The tray and its lid have a series of tiny holes that were - guess what - plugged by dust. The tray is relatively easy to remove, just two screws and a spring clamp on the overflow hose. The tray lid is heat-staked onto the tray, you should be able to clean it without separating the lid. I cleaned and reinstalled the tray and verified that water would flow properly. I then reassembled the unit and fired it up, and it's been running without a puddle for over a day in humid weather.
The unit has a filter for the recirculating room air, but there is no filter for the outside air loop. Adding a filter would obviously help keep the dust out, but it could also reduce the cooling efficiency of the unit.
DO NOT use one of these on a floor you care about without some sort of emergency catch tray underneath!

Dear ziba1--posted the same problem two days ago and it doesn't appear to be on the site yet. Anyway, picked away at this again today (literally took the machine apart) and found the problem to be a clog in the drainage system. This explains why your external tank will not fill and why there is a leak--the drip tray under the compressor is not draining due to the clog in the drainage system. I fixed this simply by taking a narrow device and gently scraping out the drain hole of the drip tray (which is located just below the compressor...the compressor is located on the same side as your air filter). After successfully cleaning out this drain, I proceeded to flush the water out thoroughly with water. Give it a try--worked for me. I had all but given up and had already set up an appointment to have it serviced. Cheers
