    Not sure but we seem to have similar problem on different model. Fridge badly iced at the back - took days to defrost after turning off as ice was thick under insulated panel. Fan in freezer compartment seems to have stopped - is that the casue? Bosch KGU34124GB - can't find model on spare part sites. Any ideas appreciated. ta Lois in London

SOURCE: Kenmore / GE side by side defrost drain keeps freezing up

Remove back of unit and check defrost heater has not become detached, otherwse the is only two possibilities, one a defrost fault and although you say the defrost tube is clear the only reason it does not flow is due to a restriction, what can happen is that the water backs up the drain pipe and then freezes before the water in the external tray can evaporate.

The fan stops during the whole defrost cycle, there is a bi metal control that determines the length of time the heater stays on. This could be the problem, if the heater stays on for the time that is allowed by the defrost timer it will get too warm in the freezer. the bi metal is located on the evaporator.

SOURCE: Freezer fan in my GE side by side refrigerator surges and whistle

With you model and brand I would want to check the voltage on the fan and shaft play. Meaning the fan may be going bad or the voltage being altered at the motherboard. I do know your model with the control board that it has if a fan becomes defective the board is also affected. If the fan goes bad and replaced it is very possible that the board will fail and cause the new fan to fail. If you need help with diagnostics please let me know, Thanks, Sea breeze

There could be a number of problems, you need to have your refridgerator topped up, or your elliment went, another solution, check to make sure that nothing is blocking the fan in your freezer

The first thing I would check is that the condenser grill under your unit is clean and the air flow is not blocked (also that the lower fan is blowing air across the coils. Even if that is not the total cause it will help your unit operate more effeciently. The condenser grill is under your unit accessed by taking off the front kick panel and also through the rear.
The second thing I would check is for ice build up around the evaporator coil (located in the back of the freezer section). If there is ice build up then you probably have a defrost system failure. This circuit is made up of the defrost heater, defrost thermostat (both located in the freezer section close to the evaporator coil) and the defrost timer which is located in the fresh food side (or if newer frig, part of the control board)

This is for a kenmore top mount Refrigerator/Freezer Model Number 25363712302. Refrigerator was not cooling properly - was warm. Freezer was working, but after a couple of days, freezer also started to...

Since you say that is isn't cooling properly, I would first start off by cleaning the condenser grill that is located under the cabinet. While this won't correct your problem entirely, it will help!
Most likely you have a defrost system malfuntion. The defrost system consists of the defrost heater (p/n: 5303918208) which is the long tube like thing that sits directly below your evaporator behind the panel in the back of the freezer (inside the freezer). It also consists of the defrost thermostat (p/n: 5303918202), which is located next to the evaporator. Both the defrost heater and defrost thermostat can be checked with an ohm meter - a non-open/infinity reading is good. If both of those check out and are good then it has to be the defrost timer (p/n: 215846602) which is located behind the plastic shield (with the light bulb).
Suggest you defrost the unit (making sure no ice or frost is behind the freezer panel then plug the refrigerator back in. If everything cools down then my diagnosis is correct and one of the components of the defrost system is bad.

Refrigerator has power but not cooling

A couple of possibilities: Coolant level has declined too far; compressor has failed, and finally, the defrost timer has failed. During the defrost cycle, the compressor is intentionally shut down and if the defrost timer has failed during the defrost cycle, the compressor will not be re-enabled.
You didn't include the model number so the following may not apply: The defrost timer is often located behind the lower grill of the unit. Remove the grill (often held by plastic tabs) and look for a small black box with a hole or a short protruding shaft. These often have a screwdriver slot to allow manual rotation in the event of a timer motor failure. If you find this, insert a flat-bladed screwdriver and rotate the shaft ~ 1/4 turn and wait to see if the compressor then starts up. If not, turn the shaft a bit further and wait again.
If the compressor does not start, either the relay that supplies AC to the compressor has failed or the compressor itself.

Coils not defrosting

Two possibilities; defrost heater failed or defrost time failed. The first is concealed inside the cabinets, the second often located under the cabinets and behind the grill.
You could at least start to look if you had even the most primitive multimeter.
BTW, not mentioning the make and model sure doesn't help us diagnose anything.

Light works - that's it! Just quit working.

All frost-free refrigerator-freezers have a thing in the system called a Defrost Timer. The thing is a little clock of sorts that tracks accumulated running time. Every 8 hours of run time the thing cycles through a defrost cycle. The defrost cycle is necessitated by the humidity that forms ice crystals on the freezing coils, if the frost is not eradicated it can build up to the point where no air flows over the coils to chill the inside of the box. The Defrost timer in all boxes fails eventually from old age. When that happens, the coils frost over until they become pretty much just a solid block of ice. Your case may however be the exception, as it seems likely that the timer quit during a defrost cycle. Most timers are located on the front of the machine, behind that removable grille under the door. The timer has a round hollow shaft through it, and can be turned with a screwdriver. If the compressor is not running, give the shaft a slow twist until a click is heard. The compressor should start. If it does, check the fridge in 12 hours to make sure it is not stopped again. Sometimes the nudge will make the timer run for a while. You will need to get a replacement timer. If that doesn't make it take off you should call a servicer.
