This defrost timer is designed for use in your refrigerator. The defrost timer acts as a clock, that switches the refrigerator from the freezing cycle to the defrost cycle and back. If your refrigerator is running non-stop, or is not running at all, you may need to check and replace the defrost timer. This is a 6 hour and 21 minute defrost timer. This part is made of white plastic, with 4 metal prongs protruding from one end. To complete this repair, you will need to access the old defrost timer which is located inside the console on the roof of your refrigerator. To complete this repair, you will need a 1/4-inch nut driver, a flat blade screwdriver, and a Phillips screwdriver. Be sure to disconnect power from your refrigerator before you begin this repair.

Freezer is cold but the other part is warm , ice keeps building up in the vents in the freezer preventing cold air from getting to the bottom part is it more likely the defrost timer or the thermostat thanks
For model number LFHT1817LB4
Hello Michael, thank you for contacting us. That does sound correct. It would be either the defrost timer or the thermostat. You can test these with a multi meter to determine which is at fault. Good luck with the repair!

Freezer working fine, refrigerator not cold ir cooling, could it be the defrost timer.?
For model number lfht1817lb4
Hello George,
Thank you for your question. For model LFHT1817LB4, we recommend the Defrost Thermostat. If your freezer is running properly, but your refrigerator is too warm or not colling properly, this is the part you would want to check first, it is available under part number PS469510. We hope this helps you.
Hi Michael,
Thank you for your question. Before removing and testing the defrost timer with a multimeter, unplug the refrigerator from the electrical outlet. Using a multimeter on the Rx1 setting, with one probe touching the common terminal (it should be labeled "3" or "C"), touch the other lead to the other three remaining terminals, one at a time. Testing the first pair should produce a reading of zero, or near zero, denoting continuity. The second pair may also result in a reading of zero or near zero. Testing the third pair of terminals should produce a reading of infinity. If you do not receive these readings, you will need a replacement defrost timer. We hope this helps! If you have any questions, please let us know.

I have a Kenmore fridge that the fridge is not cooling and the freezer will cool. At the Max setting of fridge temp will only go to 45 degrees and the freezer is 10 degrees. I removed the rear panel of the freezer to check for ice build up and there is no ice build up. I have left unplugged for 24 hours and still no luck. The evaporator coils at bottom of fridge are clean. The compressor kicks on and off like it should. The air duct between the freezer and fridge is clear of any debris. I have tried and variety of different setting still no better. It would seem it would be something simple. The other question on your web site refer to similar situation but have ice build up where as mine has no ice build up. Ideas on what the problem would be?
For model number 253.6880201e
Hello Wendy, Thank you for the question. We suggest testing or replacing the Cold Control Thermostat, PartSelect Number PS8769007. This cold control thermostat cycles on and off regularly to keep your refrigerator cold. We hope this helps.
Hi Uwe, thank you for your question. If you are looking for the position of your defrost timer, this part is located on the ceiling of inside your refrigerator section underneath the cover where your control is. I hope that helps. Good luck with your repair.

Freezer temperature fluctuates from -5 to 40 degrees. I replaced the temperature control thermostat but this did not help. Could it be the defrost timer ?
For model number FFTR1817LW8
Hello Bob, thank you for your question. It sounds like it could be the defrost timer, but I would check the defrost thermostat and heater for continuity before ordering. If the thermostat and the heater are tested and are working correctly, the issue would be the defrost control board. I hope this helps!

Freezer Freezing up and blocking the vent for refrigerator, not cooling the fridge.
Went pretty straight forward, except the heat shrink tubing was about 2 sizes too big. Would not shrink small enough to seal the connections. Even with a heat gun it would not shrink small enough. OH, another think is when I plugged the fridge back in the defrost timer was in defrost mode. Took me a few minutes to figure that out and use a screwdriver to turn the timer back to the on position. Other than that, install was pretty simple.
Discovered the coil was covered with 1/2 inch of ice because defrost cycle had not been working. Replacing the defrost timer and melting ice with hair dryer fixed problem. Hooray!

Freezer no freezing the food
Disconnect the power. To install the Defrost timer which is located inside the console at the top of the fridge I followed a YouTube video. It is very easy. Keep in mind that the Defrost timer comes settled in defrost mode so the compressor will not start after the power is reconnected.There is a hole in the console just behind the Defrost timer where you engaged it with a flat driver and rotate the clock until the compresor start. Now the compressor works for 6 hours and stop for 20 minutes for the defrosting cicle. The freezer now is freezing the meat!!

Part did not work.
This was a direct replacement. It installed easily but my refrigerator would not work at all with this part. I had to re-install my old part just to get my refrigerator to work again. I would not recommend buying this part.
