FREEZER STOPED FREEZING
It took me longer to remove all the shelving than it did to replace the part, at first I had a small short, [a bare wire was open, cut off too much casing,] thought it was faulty, but I cut back on the wire, wire caped it, then taped it with electrical tape, reinstalled, workes just fine now, at temp #6on dial. should have paid " MORE ATTENTION TO STEVE". I would highly recommend [ PARTS SELECT] TO ANYONE WHO NEEDS A PART, IF you pay attention to the video, you will find it not too difficult to repair.
Mr. PAUL KLUGH [KLU] THANK you PARTS SELECT. PS THEY would have replaced the part if need be.

No cooling in Frig or Freezer
Removed all items from Freezer. Removed back panel of Freezer (3 screws). Defrosted cooling fins with a heat gun. (about 45 minutes). Removed old Defrost Heater (2 screws). Removed two power lines from Heater. Attached power lines and installed new Heater. (Old Thermostat was O.K.). Replaced back panel. Runs like a champ. Without the defrost time, it took less then 30 minutes. I had this same project done by a service a few years ago and it cost about $300. I order the parts at about 3pm with express shipping. The parts arrived about 10am the next day.

Refrigerat
rerfrigator side not cooling After determinating that the defrost timer was running I turned it to defrost and watched tosee if frost started to melt. When it didn't I checked the heater with ohmeter, checked OK, so the only other component in the defrost system is the thermostat. Then just a matter of cutting and splicing wires and snapping the new thermost in place

refrigerator compartment got warm
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.

Freezer would not auto defrost. Food side would be warm.
Your customer installation comments were very helpful. After unplugging the unit, I took out all the freezer shelfs and the back panel (4 screws). I hadn't realized the coils were also covered in solid ice. It took awhile to defrost with a hair dryer, and I needed to use more than one towel to soak up the melting ice. Locating and splicing in the new thermostat was very easy. I used "cold weather" electrical tape to splice the wires back together. After reassembling the back panel and shelfs, I snapped in a new light shield that had been broken for awhile. It's been over a week now, and I do not see any problems. Overall, it was a easy fix. Just took a little time to defrost the coils.

Freezer was still simi-cold but refrigerator was not.
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.

Refirgerator side started to get warm. Soon after the freezer side started to thaw.
Repair was very easy. First, be sure to turn the appliance off. I removed the 5 screws holding the panel in the back of the freezer. I used a hair dryer to thaw the condenser coils so I could access the heater and related wiring. I removed the 2 screws holding the heater in place and unplugged the heater. Plugged in the new heater and replaced everything in reverse order. I then cut the 2 wires to the defrost thermostat and removed it. I attached the new thermostat to the wires with wire nuts. Then replaced the cover in the freezer and turned everything back on. It is important to use the hair dryer to remove the ice from the condenser coils.

Refrigerator and freezer are on warmest setting (1 and 1) but freezer is -15 to -10 degrees and refrigerator is 25 to 34 degrees (freezing items in the bottom 2 shelves and veggie drawer). The evaporator fan runs all the time.

Hello Frank, Thank you for the question. I suggest checking the Defrost Thermostat. The best way to do this is to remove the thermostat from the refrigerator so you can control the temperature of the sensor. You can let the sensor warm up to room temperature. With the sensor warmed up to room temperature the sensor should read approximately 6.2K Ohms at 68°F. With the thermistor submerged is a glass full of ice water, the sensor should be very close to 32°F which should read approximately 16.3K Ohms. If the values that you are getting are far off from these readings, then the sensor is bad and should be replaced. Hope this helps!

Hello Arnold, Thank you for your inquiry. The other part to check is the door gaskets to make sure that they are not leaking or defective. You can test the defrost timer before you replace it with a multimeter to make sure it has continuity. Hope this helps!

Hi Pilar, Thank you for your question. Because all the parts are in the same general area, I would make sure to check the wiring connections between all the parts and use a multimeter to verify if all the parts are working correctly. I hope this helps. Thank you and have a great day!

I've recently submitted a question about my freezer section of my refrigerator.I've just replaced the defrost temp.Sensor & the defrost heater. The defrost heater was replaced few months ago, refrigerator was working fine to about a week. 2 weeks ago I was told to replace the defrost temp sensor, done that and now the condenser coil bottom half is all iced up, almost like a block of ice while the upper half of the coils had no ice on them at all. The freezer is still about 30-40 degrees. It's getting to the point that there's no solution for this refrigerator or freezer is there?
