Can't tell exactly, too many variables, your low side pressure should be about 50 - 60 lbs, ( this is merely a guide ) temperature affects this reading. a simple way to tell is add freon and watch you indoor coil if possible. when the entire coil is sweating you are full. if only partial sweat is visible add more, a little at a time, it takes several minutes for this to circulate.

What is the cubic feet of Kenmore refrigarator model #253.562824on and also need mearsurements of outside.

You seem to be missing a few digits in the model number. Sears Parts Direct lists 11 refrigerator models that start 253.562824. (The full models numbers have 2 extra characters, including 253.56282400 and 253.5628240N.) See for the list of models.

Kenmore uses the 3rd digit after the decimal point to indicate the cubic footage of their refrigerators. With a 2 in that position, this model has a 22 cubic feet capacity (probably 21.6 or 22.1 cubic feet before rounding). Using the size of other models, the external dimensions will be between 30" W x 31-3/4" D x 69" H (the size of a 21 cu. ft. model) and 35-5/8" W x 28-1/4" D x 69-3/8" H (23 cu. ft. model). One current Frigidaire 22 cubic foot side by side model has the external dimensions: 33" W x 32" D x 69-7/8" H. (Note: the 253 in the model number indicates a product made by Frigidaire for the Kenmore line.) Unfortunately, I can't find the dimensions for any of 253.562824 models.

I hope this helps.

I have a walk in freezer with 404a, I am reading about 25 on the low side,the outside temp is about 110 degrees,its not low on freon,and everything seems to be working fine, except I cant get the temp down...

What is the high side pressure?
Are the indoor and outdoor coils clean?
Indoor and outdoor fan motors working OK?
Ice on the coils or expansion valve?
Is the unit sized correctly for the space?

Hi i have a coldmatic walk in freezzer it did not frozen anything. can itt be the controler for the temperture be broken. it run but i did not go down to the freezing temperture. what can i do?

It will not cool if its not running, if it runs all the time and is not freezing then the charge could be low. If it not running and thus not cooling then the cold control could be the problem, but there are usually other controls that are there to protect the system, such as low and high pressure switches, low ref. would open it and a dirty cond. coil would open the high pressure switch, and then both the indoor and outdoor fans need to be running, the indoor fan will run 24/7 unless its defrosting. Hope this helps

I HAVE A westinghouse a/c system in my home,one compresser for the main home an another for the up stairs.A REPAIR MAN COME TO THE HOMEM,CHECKED THE SYSTEM AND SAID I NEEDED MORE FREEON.HE ADDED SOME...

When technicians take an air conditioning course, one of the first things they learn is to use superheat to charge a fixed orifice air conditioning system.

Superheat is not hard to deal with, but the technician needs to take four good measurements.

To get the actual superheat, the technician measures suction line pressure and suction line temperature. When he reads suction line pressure, he reads the *F scale on his gauge. That's the boiling point of that refrigerant at that pressure. To get actual superheat, subtract the suction line boiling point temperature from the measured temperature of the suction line.

To read get the required superheat from the most common A/C manufacturer's superheat charts, the technician measures indoor "wet bulb" temperature and outdoor air temperature ("dry bulb"). Using these two temperatures the technician can look up the required superheat on most A/C manufacturers' superheat charts. Required superheat's can vary from 5 *F to over 45*F depending on the conditions (indoor wet bulb and out door dry bulb). The higher the load, the higher the required superheat.
The technician adds or subtracts refrigerant to decrease or increase the actual superheat to match the required superheat.

Superheat is the temperature difference between the boiling point of the refrigerant in the evaporator and the actual temperature of the refrigerant gas after the evaporator. It is the "extra" temperature (or temperature rise) the refrigerant picks up in the evaporator after it boils.

When charging the system, the technician adds as much refrigerant as he can. But if he adds too much (overcharge), he risks flooding the compressor with liquid refrigerant.

The biggest risk of flooding is under low load conditions: low outside temperatures and low indoor wet bulb temperatures. The refrigerant boils off late in the evaporator. To make sure the refrigerant is all boiled off before the end of the evaporator, the the A/C manufacturer's required superheat chart directs the technician to stop adding refrigerant when the suction line temperature gets down to within a few degrees of the boiling point inside the evaporator. The "few degrees" is the superheat. At low load conditions, the superheat is often specified as five or six degrees. It's a safety factor to make sure no liquid gets to the compressor.

At other load conditions, as determined by outdoor air and indoor wet bulb temperatures, the required superheat is given by a the superheat chart supplied by the A/C manufacturer. The higher the temperatures, the higher the load and the higher the required superheat.

Doing a superheat analysis is the best way to insure that an air conditioner has the proper charge.

How many sq ft is this frig

Length x Width will give you the square feet. Length x Width x Height will give you the cubic feet. Do you have this refrigerator or are you buying this refrigerator and want to know if it will fit in the space?

I have not measured this refrigerator. Popular sizes are 19, 22 and 25 cubic feet (capacity) which is not to be confused with physical size. If you search the device on google, you will find a vendor who will supply the specifications and then you can properly answer your question.

Thanks for your question @

Compressor contactor relay struck or relay not activated. Remove L1 and L2 wires and jumper with L1 with T1, L2 with T2 and check now. Be careful. It's only checking. When compressor starts, switch off and replace contactor relay.
