Where is the defrost timer / does my fridge even have one?

Most often the defrost thermostat fails there should be a diagram or small manual hidden under the kick panel or taped on the back of the refrigerator. I believe this model uses a computer to control all functions including defrost . There should be a way to run diagnostics on this to tell you your problem if you can find the hidden manual.

I can't find the wiring diagram for my whirlpool refridgerator.... MOD.#ET19RKXFN01 SER.#EG3222178. Can you please help. I need to change the defrost timer.....Thanks

I will try to locate a wiring diagram for your model ET19RKXFN01 but to change the defrost timer you will only need to know its location. Here is a link to the repair parts=> ET19RKXFN01_Repair_Parts_List
Go to page 5 of the repair parts list and you will see item number 4 Then on page 6 of the parts list you will see the timer part number beside the item 4. That is your defrost timer part number 2193084 Defrost Timer

Your refrigerator is an older model and may have the wiring digram in a packet behind the kick plate in the front near floor. Changing the defrost timer will not require use of a wiring diagram. Simply remove the old timer and replace the new defrost timer by plugging it into the wiring harness. The defrost timer can be found behind the control panel inside the fresh food compartment where the controls are located above the top shelf. If you have questions just let me know, Thanks Sea Breeze

Fridge working but freezer not

I believe what is happening is your freezer is not defrosting properly and your auto damper is opening just enough to keep the temperatures safe on the fresh food side. look into freezer and the rear wall. Is frost building up on the rear wall? If ye then this is a defrost issue and you will need to unplug and manually defrost with a hair dryer. Don't be afraid to remove the rear panel in freezer so you can see just what happens when defrost is not taking place. I think it is possible that you have a model LSD2615HEW but you will need to confirm before asking for parts. Inside the fresh food compartment and behind the control panel the model LSD2615HEW for example only has a Click Here=> 12002495 Adaptive Defrost Control Board I say example only because I had to assume your model number. This board is the most likely reason for this problem. Sometimes you may see burn marks on one side of board but not always. Click Here for location=> LSD2615HEW Controls and part 12 in photo is the ADC or 12002495 Adaptive Defrost Control Board The only other cause will; be a defective defrost heater or defrost thermostat. The defrost heater is=> 67004188 Defrost Heater Assembly testing of the defrost heater is also in a short tutorial on this same page. Then finally it is always a good idea to replace the defrost thermostat while inside replacing the defrost heater if need. Part number for the defrost thermostat is=> 67004757 Defrost Thermostat and can be found here=> LSD2615HEW Freezer Components If you have any questions I will be here to answer them for you, If helpful please rate this solution, Thank You, Sea Breeze

It looks like you have a 60,000 BTU unit or a 5 ton unit...12,000 BTU/ton is how you figure that...
The 60 in the model number indicates the nominal btu's of the unit... the exact output could be a bit more or less depending on the air handler...

Where is the defrost timer on a ge modle sss25jfmdww

According to the diagrams, this model does not have a defrost timer, but uses a control module which controls the defrost cycle. It is located on the back of the refrigerator behind the panel on the bottom.

Things is melting

First is it just a freezer or refrigerator and freezer? About the best way to find out what type of defrost system it has is by going by the model number. Some have a simple defrost timer located most times inside the fresh food compartment and less likely behind the kick plate at bottom front of the refrigerator. Some of the newer models have and Adaptive Defrost Control Located inside the control Panel and inside the fresh food compartment. Most times it is most likely the defrost timer or ADC that is defective that causes the problem. Next will be the defrost heater and defrost thermostat located inside the freezer and behind the rear panel of the freezer. Before doing any of this on your own I recommend that you unplug the refrigerator before removing any covers or touching anything powered up. There we will need to check the defrost element and defrost thermostat for continuity. I will help you find and solve the problem if you need and if you can locate the model number that would tell us what to look for better, Please let me know if you need more assistance or if this has been helpful, Thank You Sea Breeze

Freezer is icing over and fridge is not keeping food cold

I really believe your adaptive defrost located inside the fresh food compartment and inside the control panel is defective. It puts your refrigerator on a timely defrost and if defective this problem you listed in your post happens. Yes we may need to also check the defrost heater and defrost thermostat but with my experience with that type of Adaptive Defrost Control is famous for its failure.
ADAPTIVE DEFROST CONTROL Part Number 61005988 You can find it located on two of my websites. Some models like yours came with a Defrost Timer. We will need just look inside the control panel and see for sure. Here is a photo of the Adaptive defrost. If you should need to contact me please send an email or try to answer here. Problem is I don't get notifications when someone comments.

Please rate and ask me as much as you like. Thank You, Sea Breeze
