Question about Friedrich QuietMaster Electronic SS12J30D Air Conditioner

1 Answer

The A/C is not blowing cool air

Just moved into a new apt 2 months ago and cleaned the 18,000 BTU a/c in and out. It's in a sleeve in the wall. I did turn it on when I moved in but it wasn't hot out. Today I finally decided to cool off the room. I let it run for at least 15 minutes and tried different settings. No luck. I believe it may just need some coolent. Before I call a repair person to check it out is there any advice so I don't get ripped off?
The Model # is KM18J30C-A. It's probably about 8-10 years old. The old tenants said it runs fine bfore they left. I think they lied to me.
I would appreciate any help. Thanks, Charlie

    In your advice you gave the wrong Model #, therefore I think this is computer generated answers. Lets see. After more experimentation I notice when I turn it on at low cool I feel the cooler air and hear the compressor, just momentarily, for about 10-15 seconds. Then it's just the fan. WHat have you got to say now?

You can tell if freon is needed ,if you feel the coil,near the filter,all over,if it is not getting cold all over after 20 minutes of running,then it needs freon,make sure the coils are not dirty,and stopped up,before checking the evaporator (the one inside near wear the filter goes)

This unit probably need to be cleaned. Im in St. louis MO and its above 100 degrees with a heat index of 116 if your area is experiencing this kind of heat as we are there may be nothing wrong at all A/C units are designed up to 95 degrees when it get hotter than that the units never shut off till night fall.

My landlord installed this brand new out of the box. Our apt is 900 sq ft tops. This unit can't even cool down our living room and kitchen. If the whole 2 bedroom apt is 900 sq ft, you can imagine how...


The AC your landlord installed is rated at 8000 btu which is way too small for 900 sq ft. You need at least a 15000 Btu Air conditioner and a 'well insulated' house to be cool.
A good rule of thumb in the AC business says you need 1 ton (12000 btu) of Air conditioning for every 600 sq feet (if the house is well insulated) - if not - then you will need 1 ton (12000 btu) for every 400 sq feet.
So, if you have 900 sq feet and the house is well insulated you should have at least a 15000 btu unit.
If it's not well insulated you will need 24,000 btu.

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.

Ac not working like it used to


Storing the Unit is important -it should be up-right NOT on it side, this will cause the iol to clog the lines, NOT COOLING properly could be it need a good cleaning ( with a cleaning agent and a hose ) . to do this you have to remove the case or from the sleeve, BE CAREFUL NOT TO WATER "ELECTRICAL PARTS, clean drain line ( condensation "water" will cool off the ouside coil ( candenser) the inside coil can frost up if dirty or filter is clogged.
take the Unit out and clean well. you can purchase a spray that will remove all the grease and dirt - be careful not to bend tubing. use a light spray and let it dry in the sun. When putin Unit back in the window or wall WATER MAYBE SPRAYED OUT -DON'T STAND IN FRONT OF THE UNIT - IF you can't do this, call a serice company - this job can be done in a back yard.
