Re: Water in the drip pan- what is causing it?
I assume you are talking about the indoor unit. One function of the a/c system is to dehumidify the air. Condensation forms on the cooling coil and runs to the drip pan. There should be a drain line on the drip pan that drains the pan outside. These sometimes become clogged causing the water level in the pan to rise. Try some mild drain cleaner to open the line. Hope this helps. Let me know what you find.

It's hard to know which one needs replacing, without testing the outlet first. Unplug the AC unit and outlet in a lamp or some other electrical appliance to see if the outlet works as it should. If does function correctly, then the problem is in the AC unit. But, buying a new power cord will probably not solve the problem. More than likely, one of the circuits or sensors in the control panel got fried, when the water got into the outlet and shorted it out. That's why the reset button n the cord won't reset. Depending on the age of the uni, you may want to consider having it repaired, rather than replacing it. But, if it's 5 years old or older, I'd opt for replacement.
Now, lets address what caused the problem. Either the drain hole in the drip pan was clogged and or the rear of the AC unit did have enough downward tilt. The general rule of thumb is 1/4" to 1/2" rear downward tilt. This allows the water collected in the drip pan to flow to the rear of the unit and drain away thru the drain hole. Whether you repair or replace the unit, keep this in mind.
I hope I was able to help you and thanks for choosing FixYa.
The internal catch pan is very time consuming to replace, especially since it is located in the attic. But before you try that, have you checked to see if the drain line is clogged with algae and that it has the one inch to one foot drop you need for proper drainage? Has you house settled throwing the slope off?
If you live in the South algae growth can clog you drain line. I would disconnect the drain line (have a bucket handy) and see if it is clogged. If you have algai growth then you need to treat with bleach to kill it off. You might also want to run a drain snake through the rest of the line to make sure that it is clear.
replace it it's junk - going to do that this time because this is the fourth year of the same problem on the hottest days this intertherm junk downflow ac unit condensates where it will not and con not be captured by the pan - built by relatives of the guy who designed the titanic -
I have seen this on my unit. There was water in the drip pan under the dishwasher. Water in the drip pan comes from a leak. In my case, the water valve was getting so old that it was letting too much water into the unit when it was trying to fill. This cause the filling station to over flow into the drip pan. A quick fix - I removed the water from the drip pan under the unit and I was able to turn down on the supply valve in the basement to limit how much water could come in. This allowed the unit to run without overflowing. I will replace the water valve soon.
Other possibilities, the float device used to detect too much water in the drip pan or too much water in the unit is stuck in the too full position. Or the pump out pump is stuck and not moving water.
It sounds like your drain line may be partially plugged. Some times a small insect will get in there and cause a partial obstruction. IF the line is clear and the water continues to drip over the sides then make sure the unit is balanced So that the water will flow to the drain and not out the back.
Most likely yours has a scroll compressor which are notorious for being quite loud on start they will start for years, just a liitle noisy. Is the water from the pvc drain or from the base of the outdoor unit??
