I have the same model and have had the same problem. It has happened to me a couple of times. Once was when I turned it on after it was very humid, and the water condenses so fast it won't drain fast enough and over spills. The other time I had a problem was when it was left in "auto" mode overnight (again when it was very humid), but the fan was very slow (silent). Ice formed on the condenser and when I woke up and put it on "normal", the warm air blown over the condenser (ice) caused the ice to melt rapidly (again too much water to pass through the drain).

You may have a blocked drain or the filters may need cleaning..

pull the filters out of unit and clean with water.

check if the drain is working you can do this by pouring water into the drain tray if the water does not drain away the drain is blocked.

My 9 year old 17,500 BTU wall mounted window Unit is freezing over with little air coming out. New filter & clean coils still have same problem.


Sounds as though the indoor fan is about to give up the ghost.. 2 choices . 1 start looking for a newer more effecent unit. 2 replace the fan motor.. sorry but it does not sound good..Wiat I just thought It just might have a run capasitor ?? Not sure.. But it could be going bad as well .. Justa thought on that one. either way you can call a tech or buy a new unit.

Promac wall unit Model # PS9OCR. Unit was left on


I would suggest you check how humid it is outisde, if it is really humid it is pulling water out of the air, the drain could be plugged also. And the filter could be plugged or the condensor may be defective or plugged.

Whinny noise is probably motor which needs some motor machine oil (hardware store).

Freezing is probably caused by bad de-icing switch or poorly insulated de-icing switch.

If you want to further pursue, let me know.

Need the BTU rating for an old Kenmore K948991 a/c


Your model number is not complete enough for a model check.
However, 18,000 btu in todays' units is what you need.
