Need location of defrost timer

If your model you listed is a TFX27PRBWW it will have a defrost timer located in the fresh food compartment and behind the controls. It's location is 257 in this photo HERE I would like you to turn the timer clockwise slowly until youi hear the compressor and fans stop. This should put the refrigerator into defrost if the defrost heater is still working. Did you hear any crackling or sizzle when place into defrost this way? Wait up to 35 minutes for the timer to come out of defrost and it should restart the refrigerator compressor and fans. If it does not come on automatically then simply turn the timer slowly clockwise again until they do restart. If you need to turn timer again to start refrigerator you will need to replace the timer=> WR9X489 Defrost Timer

If the defrost timer is not the problem then we move to the freezer side, remove the rear panel of freezer and defrost the frost covering the evaporator as in this photo HERE The model TFX27PRBWW takes a=> WR51X10055 Defrost Heater Assembly

and the defrost thermostat=> WR50X122 Defrost Thermostat

The defrost heater is location 230 and the defrost thermostat is location 24 in this photo HERE Instructions in testing these parts are located on the parts pages I listed above. Please let me know if the model number is different than the one above your post so I may help you better, Thanks Sea Breeze

Yes the GSS23KGSAWW defrost is controlled by the WR55X10942
motherboard. What is happening that you would ask about a defrost timer? Let me know if you have questions, Thanks Sea Breeze

GSS23KGSAWW Service Manual

The cycle is controlled by an electric or electronic timer: For every six to 12 hours of compressor operation it runs a defrost heater element for about 15 minutes to a half hour.

Hello,

The timer is located in the fresh food section. Open the refrigerator door and look up, its in the control housing.

You can purchase the defrost timer at the link below.

bad defrost element

Most likely part number WR51X10101 Defrost Heater has burned out. Unplug and remove the rear panel inside the freezer. Defrost with a hair dryer and examine the defrost heater and look to see if burned out, It has a glass tube around the heater element and will be easy to see if burned out. If you need to replace the defrost heater you should also replace the defrost thermostat part number WR50X10054 If you don't see a problem with the defrost heater and I will instruct you on how to manually defrost to test the heater and defrost thermostat. Check for bad connections on wiring to heater and defrost thermostat. Your model has a mother control board part number WR55X10942 We may also need to check that because it does the thinking and determines the time for defrost. Let me Know what you find, Thanks, Sea Breeze

Hi, This model has a mother board instead of a defrost timer. If you are having a defrost issue, the first part you want to test is the defrost heaters. If you need instruction on testing the defrost cycle, please let me know so I can assist you further.

Thanks
