Kenmore 57072791 side-by-side 1998 not cooling

My unit will not cool at all.  Lights come on. All fans seem to work. Compressor clicks and gets hot, but coils do not get cold in freezer nor warm underneath.  When timer gets to it it seems to go through the defrost cycle (though it definitely does not need it.)  Coils inside not frozen over. Is there a way to test the starter relay? (two wires - looks clean)  Can you tell me a course of action?

    Kenmore 57072791 1998 not cooling in either freezer or fridge. Lights on. Strip between doors room temp. Coils feel a bit cooler than room. Fan runs, cannot tell if compressor is running. Visual inspection of front bottom and rear revealed nothing that looked untoward, but how would I know?

Take the back cover off and look at the frost. If the frost is only at the bottom of the coils then you are low on R-12 or R-134 and the defrost t-stat is cutting out to quick. If the coils are well frosted then you have a bad t-stat.

Please disconnect power from your refrigerator before attempting the following! You will likely need an adaptive defrost board for your refrigerator. The defrost thermostat and heater is only available as an assembly and can be checked while the unit is freezing by checking the resistance with a multimeter. there should be some resistance to the heater assembly but not infinite. If the resistance is high then the heater assembly will have to be replaced. Your model has an adaptive defrost board located in the upper right hand back portion of the control panel in the refrigerator side. This cover is removed by placing your fingers in the 2 indentations at the back of the cover one on the left and one on the right and pulling down and forward. Once the cover is off there are a couple of screws directly above the lights which have to be removed and a couple of hex head screws behind the number faceplate and on the back wall near the water filter. Once these are removed the whole housing will come down the board is at the far back right. It will either be a bare circuit board or a small white box. Just unplug it and replace it with a new one. This will correct 99% of the defrost problems on this line of refrigerators.

Have looked at the schematics for this cabinet and am unsure as to the location of both defrost thermostats as unclear on drawings. The purpose of the defrost thermostat is to overide the heater and end the defrost cycle, once the temperature on the evaporator is high enough (normally around 0'C). If you have two then one will probably control the heaters going off and the other may well control the fan, for coming back on. I.E. once the defrost has ended the second sensor will tell the fan when the coil is cold enough to come on, this prevents heat being pushed into the main area after a defrost cycle. If you feel competent enough then I would bypass the heater thermostat temporarily and see if the heaters kick in. The other thing to check is that you have a resistance across the two ends of the defrost heater. In my experience the heater is the most likely to fail, the sensor sometimes fail and the timers rarely fail. The age of your cabinet would suggest the heaters. Please do not leave the sensor bypassed as it performs an essential role. Hope this helps.

SOURCE: Kenmore Elite refrigerator stops cooling - Relay keeps cycling

the relay on the compressor is most likely the culprit part# 8201786 you can buy it at the local sears parts and repair center it is very easy to replace it. your refrig compartment will start warming up soon. to prevent damage to your compressor probably a good idea to unplug the refrig until you get the part replaced..

Kenmore side by side, fan on, lights on, compressor hot, no cool.


You probably have a bad overload/relay on the compressor . The piece which plugs onto the compressor . Or a bad fan which cools the compressor (condensor fan motor ). Also check the coils to make sure they are clean . Would need the first 3 numbers before the ones you gave , to be able to give you the part number for the o/r .

Hot to touch


there is another fan at the bottom, rear, of the refigerator. remove the bootom panel and look at the cooling fins to make sure they are not bent into the fan blades. Caefully bend the fins away from the fan. this should improve the cooling of the refrigerator and get rid of the hot spot on the rail between the refrigerator and freezer.

Freezer works Refrigerator will not cool down


The compressor should be OK this time because you caught it in time. But if the condenser fan stops you need to consider replacing the fan. I have had refrigerators do fine until the fan motor warms up and you are away, it stops. Don't think you should use the refrigerator until the fan is fixed. Sea Breeze

Freezer not freezing and fridge not cooling


Check the back wall of the freezer for ice buildup.
If yes, a defrost parts problem.
Check the freezer fan. Is it running?
If no, replace the freezer fan.
Check the condenser fan at the compressor. Is it running?
If no, is compressor hot?
If compressor is hot replace condenser fan motor.
If compressor is not hot.
Replace the compressor start relay.
