Kenmore sidebyside 53552200 stoped cooling and defrosted completly light still works both frezer and refrigerator not getting cold


It could be stuck in defrost. Check your defrost heater, and see, if it is still hot. If it is, then the defrost timer is stuck. When it goes into defrost, everything, stops working, but the defrost heater and light. As long, as the defrost timer is on, nothing else will work, as far as the compressor, freezer fan, and any cooling/freezing.

Freezer works but fridge does not


Lets see if the defrost timer being turned clockwise slowly will force defrost and cause things to get colder. On page 5 of the (click HERE=>ET4WSKXKQ02 Parts Manual ) you will see location 4? That is the 2188371 Defrost Timer

inside the fresh food com[partment at the top and behind the control panel will be the 2188371 Defrost Timer If forcing defrost solves the cooling problem then just replace the 2188371 Defrost Timer and if not we will need to check the 2176942 Defrost Heater Assembly and the 2192096 Defrost Thermostat Don't buy ba defrost thermostat until we discuss a different way of getting one to work should you need one (last resort because of cost) My focus is defrost timer and defrost heater at this point you will not need all the wires on the defrost thermostat should you need one just splice a simple defrost thermostat into the wiring harness. Below is a short movie on testing the defrost heater or click HERE Talk with me and we will get this refrigerator working, Sea Breeze

My Haier Mini Fridge comes on but keeps nothing cold. I defrosted in August and it worked for awhile and now it defrosted on its own and no longer gets cold.


This could be a bad defrost timer. See if the compressor is working. If it isn`t or only works sometimes. The defrost timer could be bad. When the frig goes into the defrost cycle, turns off the compressor. It may failing to turn the compressor back on after the defrost cycle. Since it stopped defrosting at one point and started again, the defrost timer may be bad. Let me know if this was any help or if I can help any farther.

My Bosch upright fridge is not defrosting & has a wall of ice on the back. The fan does not appear to be working either. Is that the problem? - cant remember how often I see the fan working now!Thanks


I kind of doubt that the fan is the problem. On my refrigerator, when it goes on defrost, the fan shuts off. They don't want it blowing heated air on the milk. Yours might be different.

I don't know this particular frig, but evidently the defroster doesn't work. Perhaps the fan doesn't work also, or perhaps the fan would work if the defroster were fixed.

There is a defrost timer, under the frig, accessible from the front. You can turn it with a screw driver. Turn it till you hear a click. If the timer hasn't been turning, that should turn on the defroster, a heating element nested among the freezer coils. Wait half an hour and if it is defrosting, water should be dripping into the drip pan underneath the frig. If so, then replace the defrost timer and you're good to go.

If that doesn't make it defrost, then the problem is probably the defrost thermostat, in with the freezer coils. When the frig defrosts, the defrost heater stays on until the defrost thermostat gets warm. It should be open circuit while warm. But if it is open circuit while cold, it is bad and is the cause of your defrost problem.

If you open up the freezer coils, use a hair dryer to defrost. That is safer than hot water.

I think that when the defrost heater is turned on, then the fan is likewise turned off. The defrost thermostat, I think, is doing it's job, letting it cool again. But the timer is stuck. Or something???.

Hope you can fix it.

Refrigerator on the fritz


The defroster is not working. Ice build up prevents cold air from the freezer chest from blowing into the lower part.

The way the defroster works is this: There is a defrost timer, probably found under the refrigerator at the front, that turns on the defroster three times per day or so. That turns on a heater nested among the freezer coils. It keeps heating until the defrost thermostat gets warm; then it quits defrosting.

I think your defrost timer doesn't turn. You can turn it with a screw driver till you hear a click. Now your ice compartment should be defrosting. With ice buildup it may need lots and lots of defrosting. You might not get cooling back into the lower part for awhile, till the ice buildup melts.

By the preceding, you should know if the defrost timer needs replacing.

If you should need to manually defrost the freezer coils, they are, I think, under the floor of the freezer. To defrost them, I'm told, a hair drier works better than boiling water. The defrost thermostat is in there too, a one inch unit with two wires. It should have no continuity warm, closed circuit frozen. If it has open circuit frozen, that would be your problem.
