I'm not sure what kinda timer you have there are two, one is a timer you can cycle yourself on or off the second is a defrost board does the same-thing you just can't force a defrost with it. but the way to know if it working is (defrost timer) cycle the unit in to defrost try to hear any sizzling if so your heater and defrost t-stat are ok i would replace the timer. now on the defrost board since you can't cycle it i would check the defrost element and defrost t-stat with a meter you should read a closed circuit if the heater is good, and if the coil is frosted up you should also read a closed circuit on the t-stat again replace the board. Hope this helps you

The freezer still goes but not the fridge part.


You have a unit whose defrost cycle isn't working properly. The defrost element is either controlled by an actual timer motor or it may be controlled by a circuit board. Either the defrost element is defective, the defrost timer is defective or the circuit board is defective. A very remote possibility is the defrost termination thermostat could be 'open'.

If you TOTALLY defrost the freezer compartment, your unit will work decently for about three days until it freezes solid again. The evaporator coil in the freezer is covered by the interior and inaccessible without removing the freezer shelving and the rear of the freezer interior. If the element is defective, it is located behind this cover and is imbedded within the evaporator coil itself.

GE model gth16dberww top mount freezer. Freezer is iced over. Removed rear cover and coils are also iced over. Poured warm water into drain and water immediately exited to drip pan. not sure where to


Sounds like the defrost timer is not functioning, or a defrost element is burnt out.
#1. After an accumulative "run time", typically the timer will initiate a defrost cycle. At that point the defrost heaters are energized and the compressor is turned off for the duration of the cycle. The defrost time cycle varies from manufacturer to manufacturer and can be as low as 15 minutes to as much as a half hour. If it is defective, it could be stuck in the cooling position not initiating a defrost function.

#2. If the defrost heater element is burnt out, the timer functions normally and will cycle the defective heater on, but there will be no heat generated to defrost the ice.

#3. A more remote possibility is a defective "defrost termination thermostat" which is wired in series with the defrost element. If defective, it will keep the element from energizing on a call for defrost.

At any rate, unless you are extremely handy AND have access to a supplier of repair parts, it sounds like a service tech needs to be called.

Bypass defrost timer

Just turn the defrost tmer clockwise to cause defrost or run conditions. If you bypass the defrost timer you will have problems like shorting of wiring or loss of the timed defrost. Why not replace the defrost timer if you know it is defective? What is the model number of your refrigerator? Thanks Sea Breeze

There are a couple reasons why this is happening and they are either a defective defrost timer found inside the fresh food compartment behind the control panel. Location number 257 in this photo HERE Using a flathead screwdriver turn the timer clockwise slowly until the compressor and fans stop running. Leave like this up to 40 minutes to see if this will cause defrost to take place. If this causes the defrost to happen simply replace the defrost timer.part number Click Here=> WR9X489 Defrost Timer If compressor and fans do not restart on their own then again turn the timer slowly until they do. The other reason for defrost failure and the evaporator icing over is a defective Click Here=> WR51X443 Glass Tube Heater Same part can also be found HERE It is a good idea to change the=> WR50X122 Defrost Thermostat while the rear panel of the freezer is removed WR50X122 can also be found HERE I am here should you have questions, Thanks Sea Breeze

I have a kitchenaid superba s by s. About every 3 days the freezer quits running and then after about 4 hours the freezer starts working again. What may be the problem?


Are you sure your model number is KSRD22FKST ? Sounds like the defrost timer is defective yet the model number you have above your post shows a W10351625 Defrost Control Board
9_26_2012_4_09_33_pm.jpg
In the fresh food section above the top shelf the control panel has either a defrost timer or an electronic defrost control. Unplug refrigerator and remove the face of the control panel so you can examine the timer or electronic defrost control for burn marks or signs of heat. The timer or defrost control is most likely what is causing the problems you describedand changing will more than likely solve this problem, Let me know what you find, Thanks Sea Breeze
Post the correct model number if possible, Thanks John Tripp

Kenmore elite 596 73503201 no cooling in top compartment


if the freezer is getting cold the problem is due to the cold air from the freezer not getting into the refrigerator. There are several things that can cause this problem. The coils in the freezer icing up and not defrosting properly is one of the things that can cause the refrigerator not to get cold enough. Another problem is the fan that blows the cold air from the freezer compartment into the refrigerator, not working. When the compressor is running open the refrigerator's door and push the switch that makes the light go out. You should hear the fan blowing the cold air from the freezer into the refrigerator, when this switch is pushed in. If the fan is working then you will need to find what is blocking the air flow. Iced up coils are a common problem. The icing problem can be due to a defective defrost timer or something defective in the defrost circuit. Click here for more information. Check for these problems and let me know what you have found.
