I have a kenmore refrigerator, I change the relay and overload the compressor and fan is working

Question

But it does not cool, What else can I do ?

Answer 1

A refrigerator or freezer that doesn't cool well enough may have a problem with its evaporator coils, condenser, or condenser fan motor. Frost build-up on evaporator coils, or condenser coils that are covered with dirt, dust, or lint can reduce how well a refrigerator can cool. If you notice ice getting thicker on the inside walls, inside bottom, or inside ceiling of the freezer, you have what is called a frost build-up. The problem is either with warm, moist air getting in through an old inefficient door gasket or the defrost system.

Self-defrosting refrigerators have coils and a cooling fan that need to be cleaned regularly. If the coils get coated with any contaminants, they may not cool the refrigerator properly. The coils are usually thin and black and they go through fins that dissipate heat, just like a car's radiator. They are located behind the lower kick-panel or on the back of the refrigerator. To clean them, turn the power off and use thiscondenser coil cleaning brush, or this condenser coil cleaning brush , and your vacuum cleaner. Even if your coils are below the refrigerator, you won't be able to get to all the condenser coils from the front, so it's a good idea to pull the refrigerator out and clean the coils from the front and the rear of the refrigerator. Give the fan a dusting as well. Sometimes other things can be the reason behind poor cooling, like the condenser fan motor. Anytime the freezer fan is running, the condenser fan should also be running.

A frost build-up inside the refrigerator usually means that there is a problem in the self-defrost system. You may even have damaged door gaskets. When you open the refrigerator door, you also let in a blast of warm, often humid air. This moisture usually freezes onto the evaporator coils immediately. Self-defrost refrigerators are supposed to self-defrost between two and four times out of every 24 hour time-frame. They basically turn off for a few minutes several times a day. A defrost heater kicks on to melt any frost build-up on these coils, which allows the frost and ice to melt, then it drains off to the pan underneath most refrigerators. Unfortunately, when a defrost component fails, too much frost builds up on the evaporator coils. When this happens, the circulating fan can't draw air over these coils. With no air flow over the evaporator coils, the refrigerator compartment will lose its cool.

To determine if the self defrost system is faulty, it's best to remove all the food from the refrigerator and freezer, turn your thermostat to the Off setting, and just leave the doors open for 24 to 48 hours, and let the refrigerator defrost. Keep an eye out for an overflow of water from the drip pan on the bottom of the refrigerator.

After everything has completely melted away, set the thermostat back to a regular setting. If your refrigerator starts operating properly, the symptoms lead to there being a problem with one of three other components in the self-defrosting system, the defrost heater, the defrost timer, or the defrost thermostat.

If, after testing these components, the refrigerator still doesn't get your foods cool, there may be a problem with the refrigerant level and you will need to contact a professional appliance repair person.

Answer 2

Does not cool at all?  Could be refrigerant leak.  Not easy to fix.  If it's an old regrigerator, time to get a new one.

If it's just that it doesn't cool well, or ice is building up on internal parts, that could be a fixable issue.

Answer 3

Buy a piercing valve,install it so that you are able to check the pressure on the low side.See if she is pumping or if it is low on charge.

If it is low,pressurize with dry nitrogen to 40 or so pounds,locate the leak,recover the pressure,repair the leak,and braze a permenent stub fitting where the piercing valve was,pull a good vacuum,pressurize it with dry nitrogen again to double check for leaks and vent the nitrogen,pull another vacuum,and load the virgin gas in.

I can tell you the pressure expected when needed and what else to check for a correct charge on your Kenmore refrigerator.

Answer 4

It might have a feon leak or you didnt replace the controls on the compressor right or the compressor is no good or you have the controls in the fridge set wrong.

Answer 5

Are you sure the compressor is running, you need to put a Amp probe on the wire to see what the draw is for the compressor. Since they can run very quiet it can be hard to tell if they are in deed running. The little line on the compressor is the discharge line and if it is running and has a good charge this line should be real hot. If you did fix the problem it will take awhile for the box to cool down, check the freezer fan area temp.change, any cool air is good do not rush it. If the compressor is bad or it has a freon leak most boxes have a five year warranty stop do not enter sealed system this will void warranty!
