Kenmore 75121 Thru-Wall/Window Air Conditioner Questions & Answers
Why won't my air conditioner change fan speeds
Having same problem...ac unit seems not to be changing fan speed and cooling level has been reduced ????I have no solution. but we have just run into the 7 day of 95+ degrees with high humidity. do not believe the units have frozen up, just seems that the fan is in low speed mode and trying to raise it to F2 or F3 doesn't seem to help.??? Most of the time we have to increase temperature because its too cold ?? now it doesnt seem to be cooling the same ??? I await anyones solution.
Terrible foul ordor coming from air conditioner
Two things may be causing this. A dirty air intake filter and/or the drip pan is not draining as it should.
Remove the front air intake filter and clean it, if necessary.
While the front is Off and the filter is removed, look at the drip pan under the mechanicals. If you see water standing, the unit is not draining as it should. This can be the result of the drain hole near the rear of the drain pan being clogged and/of not enough downward tilt on the rear of the unit. The general rule of thumb is 1/4" to 1/2" of downward tilt. Finding the drain hole can be a challenge, as the clog can blend in with the drain hole. Be patient and persistent in locating it. A pipe cleaner works well to clear the hole.
If none of the above applies, look for dark stains in the drip pan. These stains could be mold. In which case, add a couple of drops of bleach to the water in the drain pan. It may smell like bleach for a while, until the water dilutes it and drains it and the mold away.

Without a serial number you cannot look up on line what the unit age is. Have you cleaned the condenser coils on the bottom and back of unit?
