SOURCE: Freezer works fine...refrigerator section

Have you noticed more frost in the freezer than usual? It sounds like you may have moisture building up and freezing around evaporator fan. The fan blade hitting ice will cause the buzzing until it stops it completely or the evaporator clogs with frost and blocks airflow. If you have frost on food in freezer, check the door seals and make sure nothing is keeping doors from closing completely if you release them about 6" from cabinet.

SOURCE: refrigerator stopped working, freezer works fine

I turned off the refrigerator and left the freezer door open so the coils and the vents could thaw out. The cold air was not getting to the refrigerator section because of ice blocking the vents.

Your defrost system is bad. Replace the defrost thermostat and defrost heater in the freezer.

you have a defrost problem, could be bad adaptive defrost board,t-stat heater,when you open freezer door listen for fan if fan is blowing check the t-stat,look at it and see if it has a buldge on it,sometime you can see this and tell it's bad,you'll need a meter to read out the heater and other parts to see whats bad,might be a good idea to call a tech to do this,when you find problem you have to melt everything out again

SOURCE: refrigerator runs, cools (freezer too), then stops

In these new fangled ice boxs is what you call adaptive defrost control. Instead of the old tried and true defrost timer, brainiacs have decided to use artificial intelligence to determine defrost.
The basic pattern of adaptive defrost is:
COOLING,PRE-CHILL,DEFROST,DWELL,and POST-DWELL.
Hey I ain't making this up. The ADC (adaptive defrost control) Counts the number of times the doors are opened, the total compressor run time, and the length of time the defrost heaters were on during the last defrost. This method supposedly enables the adc to work nice in all kinds of conditions, whether hot and humid or cold and frigid climates. COOLING Mode will remain for an indefinite time or until defrost is determined by the micro-processor. When all systems are go for defrost the adc makes the jump to light speed by going into PRE-CHILL, this brings down the temps in the freezer to off set the defrost operation so that the food temp does not suffer dramatic temp rises. Pretty cool ain't it? If the ice box is in pre chill and the door gets opened then a DEFROST HOLD OFF will jump in and not do a defrost for several hours. If the door is continually opened at the end of 16 hours the adc is gonna defrost that ice box anyway. The defrost period varies but is a maximum time of 45 minutes including when the DWELL kicks in. Dwell is the length of time the ice box stays off AFTER the heater is terminated.
Then The POST DWELL will kick in. The post dwell will fire up the compressor and condenser fan but the inside fans will not run allowing the coils inside to cool down before them fans kick in and she jumps back into Cooling mode. I bet you would like to have a copy of GE's adc repair manual wouldn't you?

Control panel on front stops working, only freezer lights are lit, freezer and fridge stop cooling.


when half of the display goes out, it is giving you an error code telling you what is wrong with the fridge.Unplugging it simply resets the computer until the error comes back typically within a few hours.

without knowing what is lit up, it is difficult to help you so I would recommend putting the error code "which bars are lit up" in a comment so we can diagnose further

Neff fridge/freezer has stopped cooling


pull the unit from the wall, remove the bottom back panel , see if the small fan is working ,if the fan is , there's probally alot of dust back there,unplug the fridg. and vacuum the area real good,use a flash light to make sure you get it all, if the fan is not working and the compressor is running the fan is the problem ,the fan keeps the compressor and coils cool so the freon can cool down so the unit works like it should,if the freon is hot ,the air the fridg.will be blowing will be hot. this should fix your problem, and YES its worth fixing.alittle p.m.saves alot of $$$$$$$$$

Hi, was wondering if you could help. I have an Electrolux fridge Model ER6632I that has suddenly stopped cooling. This fridge is approx 8 yrs old. I opened up to the rear of fridge and found that...



Seems that the compressor has some fault within the unit as it takes in more current under pressure. Sometimes it can be due to fault within the compressor, failure of the valve , O-rings. Now shut down the fridge for about 6 hours and then 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 RPM of motor is low check capacitor.

Freezer works fine, fridge compartment cools but has stopped cooling as good and has recently stopped cooling. did a manuel defrost on fridge and freezer worked fine afterwards, now doing the same thing...



Oncce the fridge was shut off and left for a while the cooling had come back . If frost is seen it is a good indication as the compressor is working with sufficient gas within.
If after about 6 hours you observe cooling it is possible that the defrost timer is faulty.
Earlier make sure that the thermostat was set to normal mode for freezer and fridge.
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.
If defrost timer works but frost keeps forming check while the compressor shuts if the heaters are working, check continuity of the heaters.
replace the defrost timer, heater or thermostat one you have confirmed to eliminate one by one.

NEFF K4663 fridge. the freezer works ok but refrigerator space does not go below 9deg C even at highest setting. have defrosted and water drain is clear.


The defrost board is not functioning properly.;

When the freezer section gets cold and reaches its required cooling temperature, after that the frost on freezer section starts defrosting and the cooling fan in the freezer section blows this cool air from freezer to fridge. But if the defrost cycle does not start then over ice will get collected on freezer ventilations and that will block the air passing section from freezer to fridge, so the freezer gets cool but fridge section does not cool.Try manual defrost by unplugging the refrigerator from main power outlet for 4 hours then reconnect it and check, if the same problem is noticed again,. If yes then its defrost board problem. The defrost board located in the back of fridge section. You can get required parts from www.repairclinic.com or from online sears part site. ------------- Thank you.

Both Lights flashing and fridge not getting cold


I turned the fridge and freezer off using the circular dials, I then turned the unit off at the mains. Left it for a few minutes and then turned the power back on. I then turned the circular dials to "max" and then depressed the super cool and super freeze buttons to turn this facility on. This time they came on normally (not flashing) and no alarm sounded. The fridge and freezer then started to get cold. Once the unit had been running for several hours I then turned the dials to the 3/4 mark and depressed the super cool and super freeze buttons again to turn them off. Over night the fridge and the freezer appear to be working properly so I hope that my problem is solved. Maybe the unit just needed to "settle" before being switched on?
