Kenmore Elite Bottom Freezer Mod. #795 75544401

It will not defrost. Ice is building up on the back of the freezer and on the left side of the right hand freezer drawer. Where is the defrost timer control? Could this be the problem?

    Where is the defrost timer control for my Kenmore Elite Bottom Freezer Model #795 75544401?

    What information do you need to be able to tell me EXACTLY where the defrost timer control is located? I had already assumed it was on the fridge somewhere. Do you need the serial number also?

    I will try one more time. Your answer was in great detail, but it did not answer my question. In your answer was #4 Locate the defrost timer...
    That's what I've been trying to find out. Short of dismantling the fridge, WHERE IS THE DEFROST TIMER LOCATED?

    A very frustrated Tenthumbs!

    The serial is #601KR00406. I'm sorry to be such a pain, but I'm 73 years old and walk with two crutches, so I don't have the dexterity to go fumbling around removing unnecessary parts. I've already paid for a service call to find out that it's not defrosting. Brilliant deduction when the freezer compartment is frosting over, but the evaporator coils are frost free.

    After multiple responses, I am no better off than when I asked the first question. I suppose I have no other choice but to accept the responses (including the multiple identical responses from thaurfen), but my original question was never answered.

While the freezer is cold, cut out defrost thermostat and measure resistance, if open, replace, if it's ok check defrost heater.
Temporarily short the wires that went to the defrost thermostat and now force defrost.
If no defrost, you have a bad adaptive defrost board.

The thermostat cycles the refrigerator on and off. The refrigerator normally runs as long as the temperature inside the refrigerator is higher than the set temperature. If the temperature inside the refrigerator is cold enough and the thermostat still does not cycle off, the thermostat may be defective. If so, you need to replace it, because it cannot be repaired.
If the thermostat is not defective, you may have a problem with the sealed (refrigerant) system, in which case you should contact a qualified appliance repair technician.

    The defrost timer is often located at the bottom of the refrigerator, near the front and behind the kick plate.

Excessive ice build up on the shelves or walls will fool the thermostat into not coming turning the compressor on
Do Not use any sharp objects to scrape or chip ice in the freezer as you may damage the coils, which are the shelves or walls in a manual defrost freezer. You can use a hair dryer, shop vac, a fan setting in front of the freezer with the door propped open or set pans of hot water on the shelves to help melt the ice. If you poke a hole in the coils and the freon leaks out, start looking for a new freezer as it will not be worth repairing.

  • 1) Unplug the refrigerator.
  • 2) With the freezer frozen down, (it must have been running at least a couple of hours to give the contacts in the defrost thermostat a chance to get cold and close) remove the evaporator cover (the cover in the freezer that covers the cooling coil)
  • 3) Plug the refrigerator in.
  • 4) Locate the defrost timer and, with a screw driver, turn the timer to the defrost mode. ( There is a slot on the timer that the screwdriver will fit in. Turn it clockwise. The refrigerator will stop running when it goes into the defrost mode.)
  • 5) Wait about 5 minutes, then see if the defrost heater is heating. It will get VERY HOT, so be careful! If it is heating, the defrost heater and defrost thermostat are good. The timer should be replaced.
  • 6) If the heater is not heating, then the timer is probably good. (While this is not true ALL of the time, in my 15 years in this business I have seen this NOT true only twice. You could still have a bad timer, but is is unlikely)
  • 7) UNPLUG THE REFRIGERATOR!
  • 8) Use a hair dryer to defrost the evaporator (cooling) coil.
  • 9) Visually inspect the defrost heater. Check for a broken or burned area on the heater. Replace the heater if you find this.
  • 10) If you do not have a multi-meter, skip to 13. If you have a multi-meter, check the resistance of the heater by disconnecting the wires from both end of the heater and, with the meter set to "OHMS", put one meter lead on each end of the heater.
  • 11) If you get no resistance reading, replace the heater.
  • 12) If you get a resistance reading, replace the defrost thermostat. (See 6 above.)
  • 13) If you do not have a mulit-meter, make sure the refrigerator is unplugged, then locate the defrost thermostat. It is a round, quarter sized part with two wires coming out if it. It usually mounts directly to the evaporator coil.
  • 14) Make a note of how each wire is attached to the thermostat.
  • 15) Remove all wires from the thermostat.
  • 16) Using a wire nut (you probably removed two of them to remove the wires) connect ALL of the wires that WERE attached to the thermostat together. (NOT THE WIRES THAT ARE MADE ONTO THE THERMOSTAT, BUT THE WIRES THAT WERE ATTACHED TO THE THERMOSTAT)
  • 17) Plug the refrigerator back in. Make sure the timer is still in the defrost mode.
  • 18) Wait a couple of minutes, then check to see if the heater is heating. It will get VERY HOT, so be careful.
  • 19) If the heater is heating, replace the thermostat.
  • 20) If the heater is not heating, replace the heater.

      the link is having proper diagrams of the timer please check it sir.thanks.and do not forget to rate the solution.

    • tech expert12 Aug 29, 2008

      the timer is located on the rear of the unit, behind the kickplate, of in the console area

    • tech expert12 Aug 29, 2008

      located inside the freezer, on the right side behind the white plastic panel.



      Be careful when removing the white panel because a fan is mounted to the left side of the white panel and plugs into the back left side of the freezer compartment.

      technical help is much advisable as it will just take 15seconds to locate the timer.



      please rate the solution sir.

    They are often hidden behind the back bottom corners of the fridge at the bottom, in the last few years the timers have been located in the ceiling of the fresh food section, and some behind the cold control cover.

    Hope that helps.........

    Kenmore classic bottom freezer refrigeration warm but freezer is cold


    I would guess you have just caused a build up of ice to block the air way, which normally takes cold air into the fridge. manually defrost (unplug and wait until the ice goes away) then restart and it should be fine

    where is the ice,is it on the food and shelves or is it on the back inside wall of the freezer?if it's on the back inside wall of the freezer you have a defrost problem,bad defrost thermostat,heater,timer or board depending on your model number,if it's on the shelves,door and food packages warm air is getting into the freezer somehow either from the door not closing or the door was left open,could have a bad gasket on the door,the ice chute door could be broke and not closing.let me know what you find and the picture shows a side by side but i'll need the model number too,if it's a side by side or freezer on the bottom the model number should be in the fridge section,on the right hand wall up near the ceiling,if the freezer is on top the number should be on the left side wall in the fridge section up near the ceiling.but with this hot wheather we're having if the door was left open this will happen,you can shut down the machine or unplug it,remove the food from the freezer and melt the ice with a hair dryer,don't do this with the machine running because the hot air will cause the same problem,after the ice is melted you can put the food back in and restart it.

    I had water in bottom of kenmore fridge. This is now fixed but soon after I had frost building up on back wall of freezer.


    you now have a defrost issue,remove rear panel inside freezer if the evaporator is covered with a heavy ice and frost build-up then either the defrost heater under the evaporator coil is open or the defrost thermostat on top of the coil is bad you need to check both for continuity or the defrost timer if equipped or the A.D.C. adaptive defrost control is bad and not supplying power to the defrost circuit

    Water leaking into freezer


    It may be the defrost thermostat. This thermostat turns on a heater in the freezer a couple of times a day and melts the ice in the freezer which should go into a tube that leads to a pan underneath the refrigerator, where it sits and evaporates from the heat of the compressor. It could also be the timer which tells the refrigeator to turn off a couple of times a day and tells the defrost thermostat to turn on.

    Kenmore elite - top freezer


    if there is ice build up at the back wall of the freezer section, then you have a problem with your defrost cycle. the freezer would not be very cold for the ice maker to work.

    it's either your timer, defrost heater or your bi-metal.

    The unit was built bt LG. It is a computer controled unit and the timer is built into the main control board on back of the unit. However, the most likely cause of the broblem is the defrost terminator located on the evap on the upper right hand corner. Also, try unpugging the unit it will reset the computer board. You will also have to defrost the unit.
