It turned out to be a defective defrost timer. The bottom of the freezer box was removed to find the cooling coils covered with a block of ice. A hair dryer was used to thaw the ice, the timer replaced, the heater checked and then reassembled. A few clues to those with a similar problem......First clue....I failed to notice that the fans never stopped. Usually during the defrost cycle the condensor fan stops. The constant running fan should have tipped me off that the timer was not advancing. Second clue...I failed to notice the absence of water dripping into the evaporation pan below the fridge. Dripping water would indicate that the heater was melting ice on the cooling coils. No dripping water should have told me that the ice block was getting bigger. I'll know to check for these telltale signs in the future.

    How did you remove the bottom of the freezer block?

It was determined to be a malfunctioning defrost timer. The freezer box bottom was removed (not an easy thing to do) and the coils found to be a solid block of ice. The timer would not start the defrost heater, hence the freeze up. The timer was replaced and the chill box is back in action.

Refrigerator and freezer not cooling


Top of Form

If there is no cooling at all , before we go further we must confirm the first step of confirming the compressor and gas pressure. So shut off the fridge and leave it off while you clean and check the evaporator for frost. If frost is seen it is a good indication as the compressor is working with sufficient gas within.
Now after about 6 hours plug in the fridge to start. Observe cooling to happen in about one hour and ice to from under three hours.
Earlier make sure that the thermostat was set to normal mode for freezer and fridge. If there is no ice formation we have a big issue as the compressor and gas must be checked out. If compressor is running check the pressure, get help to test gas pressure. If not you will need to fill up ,If gas pressure is good the possibility of the compressor being inefficient is high. In such a case you must take consensus to estimate and decide, if RPM of motor is low check capacitor.
However if Ice forms then observe the fridge for about 24 hours for cooling to continue and the fridge to cut off. If not the auto defrost timer, or the thermostat must be checked.

The ventilation fan that circulates the COLD air from the evaporator coils could get clogged with frost and so could be jammed. Also the wires to the fan can be worn out due to the frost. If so check if the defrost timer works to switch the heater to remove the frost. Also the check if the compressor is shut down by the timer /thermostat . If the heaters are not working, check continuity of the heaters.
So attempt to test using a multi-meter / clamp tester from the outside and make your observations so that we come to the solution.

sounds like the compressor is not running. The condenser fans are located at the compressor. The fans in the conditioned space are the evap fans.

Refrigerator not cooling


If the refrigerator isn't cool, you need to answer some questions, then see if the compressor is running.
First, answer these questions:
Is the refrigerator completely dead? If so, see “It's stopped completely.”
Is the thermostat knob turned to the proper setting? If not, reset it.
Next, see if the compressor motor is running
The compressor is a football-sized case with no apparent moving parts. It's on the outside of the refrigerator at the back near the bottom. If it is humming or making a continuous noise and your refrigerator is still not cooling, there may be a more serious problem with one or more of several different components, we recommend contacting a qualified appliance repair technician for further help.
If the compressor is not running but you do have power to the refrigerator, there may be a problem with one or more of these:

The compressor

The Thermostat

The overload, relay, or capacitor

The defrost timer

The condenser fan motor

Cooling is poor
For an overall understanding of how refrigerators should work, read about refrigerators in the How Things Work section of our website. A refrigerator or freezer that is cooling, but cooling poorly, may have a problem in one of several areas:

Poor cooling is often the result of a heavy frost build-up on the evaporator coils or a condenser that is clogged with dust, lint, and dirt.
Evaporator coils
Poor cooling is often the result of a heavy frost build-up on the evaporator coils. You can't see these coils without removing a panel on the inside of your freezer. A sure sign that there is a build-up is the presence of any frost or ice build-up on the inside walls, floor, or ceiling of the freezer. Such a frost build-up usually indicates a problem in the self-defrosting system or damaged door gaskets.
The refrigerator is supposed to self-defrost approximately four times in every 24 hour period. If one of the components in the self-defrosting system fails, the refrigerator continues to try to cool. Eventually, though, so much frost builds up on the evaporator coils that the circulating fan can't draw air over the coils. There may still be a small amount of cooling because the coils are icy, but with no air flow over the coils, cooling in the refrigerator compartment is quite limited.
Here's an inexpensive, though inconvenient, way to determine if the problem is with the self-defrosting system. Remove all of the perishable food from the refrigerator and freezer, turn the thermostat in the refrigerator to Off, and leave the doors open for 24 to 48 hours. (Be sure to have several towels ready in case the melting frost and ice causes the drip pan to overflow). This allows the refrigerator to defrost "manually." When the frost and ice build-up has completely melted away, turn the thermostat back to a normal setting. If the refrigerator then cools properly, it indicates a problem with one of three components in the self-defrosting system:
The defrost timer
The defrost thermostat (also called the bi-metal switch)
The defrost heater

to check these components .... please refer to my solution in the below link....

http://www.fixya.com/support/t4189238-defroster_not_working_checked_defrost

If it still does not cool properly, there may be a problem with the refrigerant level or the compressor. You may need to consult with a qualified appliance repair technician to further diagnose the problem
Condenser
Self-defrosting refrigerators all have a set of coils and a cooling fan, usually under the refrigerator, that need to be cleaned regularly. If these coils get coated with dust, dirt or lint, the refrigerator may not cool properly. The coils may appear to be a thin, black, wide radiator-like device behind the lower kick-panel. To clean them, disconnect the refrigerator from the power source, use a refrigerator condenser brush (see the Appliance Accessories section) and your vacuum cleaner to clean the coils of any lint, pet hair, etc. You may not be able to get to all of the condenser from the front, it may be necessary to clean the remainder of the condenser from the rear of the refrigerator.

My Ge profile with freezer on the bottom is not cooling. The fridge is 60 f or 15 C. The coils are clean and frost free. There is some frost on the copper tube that is surrounded by a foam wrap where it...


It is froze up there is no cool air going to the bottom. sometimes one will do that. defrost timer did not work. or the heat coil is bad. unplug it for about 8 hours to let it throw. and see if that will fix it. If it runs ok for about 5 days and dose it again. it is not defrosting.

Water runs under the vegetable bins


There should be a collecting channel with a hole and a tube reaching down to somewhere above the cooling compressor (Back of unit) where it should evaporate with the heat.
Most people never clean that hole and tube simply because they do not know what is for or the manual is silent. Sometime can be jammed with little icecube. I us thick plastic line from toy to clean, electrical wire with copper core not naked is also oke. Do not put wild force. This is the cooler part. The deep freezer part needs defrosting on temporarily basis and for that you need some small low bin to start collecting or keep on mobbing the floor.

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.
