Hi,
Yes you could have a leak or the compressor could not be working....

Check the compressor and see if it is working or not....

If you do have a leak then I would buy this product.

To see if it is leaking you will need someone to put gauges on it and see if it is charged properly....

What is wrong with the Kenmore Elite refrigerators they have now? I bought one and it is very noisey. I hear the compressor running from rooms away and it's not a rattling just the noise of it running


If you are wanting to check and see if the compressor is operating and actually working, find the small refrigerant line coming off the compressor and follow it several inches and check its temperature. The normal temperature is over a 100 degrees and should feel very hot. Be careful the normal range is over 140 degrees on most model and may cause burns. If it is hot to the touch, that means the compressor is working. If it is not hot it means you have some problems with the compressor and probably need a new one.
If it is hot, the most common problem with a real hot compressor is a dirty condenser. If your models compressor hot line dissapears into the casing (walls of the refrigerator) then you cannot clean the condensor, but if it goes into a finned condensor with a fan, you need to check if it is dirty and just needs cleaning. This is a very common problem and periodic cleaning needs to be performed. Your refrigerator loses heat removed from the interior by rejecting the heat to the air passing over the condensor. If it can not breath due to dirt buildup, the refrigerator will over heat and lead to prematur breakdown. If the systems has operated long enough at a high temperature, the refrigeration oil in the refrigerant system can decompose and form sludge and block the capillary tubing. Once sludge start forming it is very difficult to flush the sludge out and a compressor change out typically can not fix the system because remaining sludge. In this case it is cheaper to buy a new refrigerator and remember to clean the condenser every year at least, more ofter if you have cats and dogs. They have a tendency to shed and the hair gets into the condenser. I had a customer once that used the air flow to the condenser as a vacuum cleaner because the dirt dissapeared near the air suction, until the condensor clogged up and the refrigerator stopped cooling, go figure.
Hope this helps

Sub zero 642 refrigerator not cooling


Being a sub zero tech and actually fixing that exact model earlier today I would recommend you call a qualified service tech to come take a look. If not, I'll tell you the steps I would take to isolate the problem. 1) check to see if the refrigerator fan, also called the evaporator fan, is running. Just open the door, hold in the switch next to the light switch and listen. You'll hear it easily if it is. 2) If fan is running remove the grate up top, the one you took off to put the condensor fan motor, and see if the right side compressor is running. Don't always go with if its vibrating its running because the freezer compressor or the condensor fan can cause it to happen. Find the high side, or condensor line which is the smaller that comes out of the compressor in the back and runs up front to the condensor, and feel if its hot. Hot = good, cold = bad. Note that all this can be avoided if you have a set of freon guages because that model has access taps already on them. They are wrapped in yellow. If you have guages unscrew the cap and connect the guages. On the outside numbers the needle should be around the 25-30 on the positive side. If its in the green area, the negative, around the 10 you need some freon, and possibly have a micro-leak that needs repairing. If its down in the -20 to -30 area you have a serious leak, more than likely in the evaporator inside the fridge, and you should relay call a tech. Now if the needle jumps way up to 70 or 80 and the compressor is hot, really bad, call tech. and if it does that and is cold, the compressor is just off. Now if your still with me and stuck through this far i'll give you the cliff notes.
If the temp is 55 that mean the fan inside is running, and that more than likely the compressor. Now here are some questions to ask yourself. Are the condensor coils clean? That would raise the temperature. You just changed the condensor fan motor, did you put the blade back on right? If the air flow is blowing across the compressor in the direction of the freezedr compressor, your blowing really hot air from the condensor across the compressor and your temperature will raise badly. Fan draws air across the compressor and through the condensor. Worse case scenario you jacked the control board up inside, which I dont think is the case either. ** check that fan blade **

Problem in Refrigerator


Hi,most times when the refrigerator is not cooling the problem is usually from the condenser or a leakage in the pipe that carries freon gas from the compressor to the cooling compartment in the unit.
In actual fact,cleaning and refilling the compressor as the service man implied should take care of the problem,but if he now says it requires to be repaired/replaced probably he discovered a great leakage or a fault with the pumping system of the compressor.If he spotted a leakage,tell him to take the compressor to a panel beater to help block the leakage,this will save you money,
But if the problem is complicated than that,you might have to replace the compressor as a lasting solution.
Thanks and take care

Kenmore Refrgierator is not cooling enough


Is the frost on the entire surface of the evaporator or just a portion. If it is only frosting on a portion there is a possibility your system has developed a leak and has lost some of the charge. Or your compressor has lost its ability to pump the gas. A bad condenser fan motor overtaxes the compressor and can cause premature failure. If it is a bad compressor it may be time to replace the refrigerator. Replacing the compressor is an expensive job and the warranty is only one year on a replaced compressor.

KENMORE TRIO 2004 59675523400 REEFER/FREEZER NOT COOLING


It is the compressor that has failed. The hum is it trying to start and the following click is the overload protector opening. What is the temperature where the refrigerator is located? Allow the compressor to cool down before trying to restart it. If it still does not restart after it has cooled off it is done.

Refrigerator cools, but no freezer fan & no condensor fan running


Check the back of you fridge and make sure the coils are clean. If you have access to a small air compressor, blow everything out and make sure the motor are is clean. The build up of dirt on the coils will not let the heat escape during the cooling process.
