Called a friend that lead me down the right path so i did a search for the part's and found this site. The trouble shooting that outher's had done was the same as mine, I descovered that the coil's in the freezer had frozen up complety. They are located behind a plasic cover in the freezer area, it had frozen up due to the Defrost heater element being defective, when i took it out it was black and burnt looking,It is located at the bottom edge of the coils,2 bolt's and a plug in on each side. That is probally the only part i needed but i went ahead and replaced the sensor and timer also.The sensor wires in the freezer( located on the very top of the coils) had to be cut and the new ones spliced in, only 2 wires and easy access. I also put shrink wrap on the splices to protect them from mosisture. The timer was located in the fridge area by the temp. control knobs. 2 small bolts and a plug in was all on it. It's been 5 day's and so far so good. The worst part was defrosting the frozen coils. This was done with the wife's hair dryer and a couple towel's to soak up the water. Don't just let the water go down the drain hole because the tray that catches it will not hold all the water from the frozen coil's. Just a reminder, don't forget to unplug the unit when working on it. Hope this help's and was very easy install, Cost about $125 in part's and a couple hours of labor(did a good cleaning while it was eampty for the repair) Good luck.

Fridge was not really cold. Fan was working at back of freezer. Romoved the drawers and back panel of freezer compartment. Melted ice with a blow dryer and collected water with a towel so that it would not overflow the drip pan. Installed the new defroster units with 4 screws and the easy plug in wiring harness. Bingo! Defrost timer was probably OK but new one is easy to do.Fixed in one day vs waiting for service call & payng $$$.
Per the trouble shooting guide on the home page of the website. I suspected the defrost timer was bad because ice had heavily accumulated on the back wall of the freezer compartment and the temperature inside the refrigerator was warm. First, I removed all the freezer racks. Then removed the (4) screws on the back wall in the freezer compartment. I then removed the ben from the ice maker to allow more room. Once I saw all the ice, I unplugged the refrigerator, and used a hair dryer to defrost ( it took about an hour to get it all). Once the ice was all gone, I then moved into the refrigerator compartment and removed the top shelve. This allowed me more room and access to the defrost timer which was behind the back panel. I used the trouble shooting guide to test the old timer prior to removing the new one from the package, (just in case I needed to send it back). Through this test I determined that the timer was bad, it wasn't the heating element or the t-stat. It was very easy to access, I removed the two knobs and lifted up the panel. I located the defrost timer and removed the screws as directed. I replaced the timer just as I had removed it, plugging in the electrical terminals per the removal process. I then reversed the order and put the panel and top shelve back on. Once all complete, I then moved back into the freezer compartment and replace the back panel and then the ice ben. I plugged it in and haven't had a problem since. This site has saved me a tremendous amount of money, a service contractor quoted us $300, to determine the problem. I ordered the part and it was sitting on our door stoop the next morning.
The appliance is relatively old. Sears estimated the cost around $300 dollars after diagnosing a thermostat problem. Looked online for model and part number and found Partselect.com. Good reputation on BBB. Site was very easy to use, good customer service and quick delivery. Replacement was easy. Temp control and timer located inside the appliance. Removed temp knob, plastic cover, light bulb and 1 screw to dislodge housing and unplug power. 4 screws to remove temp control unit and timer from metal housing. Took images before disconnecting connectors. Replaced parts, plugged power and re-screwed onto housing. Put back the housing, bulb, plastic cover and knob.Plugged in the appliance and turn on the temp control. NOTE: defrost timer needs to be adjusted with flathead to enable the appliance. Once the timer was enabled, unit is functioning normally. Saved myself $200.
Couldn't find schematic or repair manualFinally found your site which showed the location and part numbers of the timer and heaters.I ordered them; they came immediately.I replaced only the timer, since it was the easiest and took only a few minutes. Defrosting the frezer coils with a hair dryer took about an hour.Rerigerator froze over again in about two weeks.I then replaced the heaters. One of the heaters was 'open circuit'.
First i unpluged the power then cleaned everything out of freezer and removed all the drawers and racks them removed the 2 screws at bottem of freezerand removed panel then removed 4 screws on the bulbs and unpluged the wire and took off the sensor and replaced with new one put everthing back. Then on the top of refigerator side on the top behind the adjuster is the defrost timer pulled handle out and off removed plastic shield and removed 2 screws and unplug the timer and change it then put everything back and pluged back in and everything worked in a few minutes
1. Unplug, remove control knob from both temp control sliders, remove upper light bulb and light shield from refrigerator compartment. 2. Remove screw holding top of bracket control mod in place. 3. Lift bottom tab from slot and remove control mod from ref compartment. 3. Unplug temperature control and defrost timer and replace. (Each are held in place with two screws.) 4. Replace control mod. This part took me the longest because the space between the top of the control mod and the top of the ref. compartment is very small and replacing the nut was difficult. Use a nut driver with a long shaft. 5. Use screw driver to turn control button of defrost timer to start cycle. 6. Replace bulb cover and light bulb. 7. Set temp control to initial setting. 8. Have a Margarita and celebrate. It's been over a week and the refrigerator/freezer is working perfectly.
The comments from customers experiences gave me the confidence that the defrost timer was the problem since the compressor was still working and it went just as they all said, four 1/4' hex head screws and I had access to the old timer, unplugged the old ,plugged in the new and put the four screws back in. Nothing happened so after a while I looked a bit harder at the accessable part of the timer after intallation and saw what looked like a dial. I turned the dialclockwise and immediatly the compressor turned on. I have not found any information as to how much or little to turn this dial which obviously is an adjustable cycle setting so I just turned it all the way, so far everything is working alright.
Got part overnight. Unscrewed cover plate at top of regerator compartment, disconnected old part, connected new part. Screwed back plate. Voila!I saved a bunch of money!
pretty straight forward,removed threw screws to replace the defrost timer and reverse the procedure. To replace the defrost unit 1st removed metal back plate in freezer. Step 2 defrost freezer. step 3 remove four screws that hold defrost elements in freezer compartment. Step 4 install new defrost elements and secure back in place with four screws. step 5 optional read old defrost heaters with ohm meter to confirm the defective part. step 6 plug back in frig and enjoy a cool brewski ahhhhh. By the way only one defrost element was bad (open) but as mentioned in literature which came with new derost elements I replaced both of them. Thanks again for all the help on this, saved me $2000 on a new frig.
Removed cowling unpluged timer and pluged in new one.Great Service, got part in one day
After a little research I realized my problem could be one or possibly two components of three that caused the problem. Instead of changing one at a time, I took another approach. I just bought and changed all three to save time and prevent having to do the job all over again. Each time I would have to melt the ice off of the cooling coils and this is time consuming and annoying having to melt the ice repeatedly. I put a very accurate thermometer in the fridge and have been monitoring it since I changed the components. After one week it seems to be working fine keeping the fridge at 34-38 degree F.
After diagnosis though Part Select I determined it must be the defrost heater. I took the panel off on the inside of the back wall of the freezer and used a hair dryer to thaw the ice buildup. I found the bottom element was burned out. I ordered the defrost heater kit and the defrost timer in case that was faulty too. Parts arrived next day. I installed the heater kit and replaced the panel. Then took off the plastic cover inside the refrigerator. One screw near the top of the metal box allows you to remove it to get to the defrost timer.
This is a old 2000 side by side Kenmore frig bought from sears. left Freezer side was building up ice in the back, while right side was not cool at all. The Defrost Timer was behind the light panel on top in compartment side. Easily remove unit and unscrew things. Works like a champ.
Removed housing around timer. Unpluged andreplaced timer. Defrosted freezer witk small portable heater. Freezer has worked greater since.Saved a lot on service call.
