Refrigerator and freezer not cooling as required, compressor running continually
Turned refrigerator and freezer controls to off, removed icemaker bin, unplugged icemaker plug and removed two screws holding icemaker in place and removed icemaker. removed screws holding auger motor and freezer compartment light plate, unplugged and set aside. Remover screws holding freezer coil cover in place and removed cover. Allowed coils to defrost completely and then removed screws that hold the two defrost heater coil mounting plates in place, unplugged the two wires that connect the defrost heater coils to the connector block that is located above the freezer coil. Remove the entire defrost heater by working the connecting wires out from along side the freezer coil. Remove the clips that hold the old defrost heater elements to the mounting plates. Install new heating elements into the two mounting plates with the clips. Reinstall the two mounting plates to brackets on freezer coil and reinstall connecting wiring up to connector block and reconnect them. Reinstall freezer coil cover, icemaker auger motor and freezer compartment light plate, and icemaker and bin to complete job. Due to the confined space in the freezer compartment, reinstalling the freezer coil cover and light plate was difficult as I could only use one arm at a time resulting in many dropped screws.

Refridgerator constandly running
Turned out the defrost heater has burnt out in the freezer compartment on both heater tubes. To get to it. 1) take out all the shelves 2)remove the light bulb 3)unscrew 6 screws for back panel 4)Mine had a lot frost build up on the evaporator coils which I used a portable heater to defrost. which it took about 2 hrs to get all the frost thawed out. 5) Defrost heaters are located below each of the coils remove 2 screws on each plate there are 2 plates holding the heaters in place. 5) You may have to bend the sheet metal in order to get the heaters out and trace the wires to where it connects to towards the top or the freezer. 6) Put in the new heaters and plug in then put back together. 7) I also replaced the Defrost thermometer which it is easy to replaced while I had it apart. Now the fridge works perfect just like new.

defrost heater burn out
Frist pulled everything out of freezer put in refridge then took out ice maker box then removed ice maker motor removed back panel took hair drier defrosted the coil then removed bracket screws that hold heaters in place removed bad heater, the hardest part of the job was getting the wirers back around the coils when done just reversed the process.I have a side by side so there was not a whole lot of room to work with. I only weigh 160 lbs it was a tight fit for me. But all in all it went well.
Thanks

Ice Build Up On Evap Coil
Removing the old heater coil was a bit of a task as you need to take off all the brackets holding the heater coil and then remove the wiring from back of the coil. Installing the new heater coil assembly in the brackets and feeding the wirings back up to the top was a major task. Need to have long arms as the heater is located way back in the freezer compartment. The part was the exact match. The part was delivered in 2 days. Thanks alot. Will use your site again.

Freezer-side cold; Fridge-side warm of side-by-side Refridgerator
evaporator coils were frozen solid and air wasn't flowing across them

read all directions first, then consider which steps you'd like to take

in any case...
- check for blockages in the upper and lower air vents that allow air from freezer side to cool the fridge-side
- inspect that the fan in the freezer side is actually turning and not blocked


- if no blockages and air is flowing between the sides...

- unplug the unit
- remove all goods from freezer and fridge
- remove freezer side racks
- remove rear panel on freezer side using philips screwdriver (note that the ice-cube tray motor housing must be freed by removing its screws. it can be pull out a bit to get to a single screw holding the top of the rear panel in place)
- allow the evaporator coils to evaporate all ice off, checking the drain pan under the fridge frequently - accelerate the process using a hair dryer or paint stripper (heat gun)
- disconnect the white wires from the connection block located about 2/3 of the way up the rear wall and check resistance using an ohmeter (see specs on back of fridge on circuit diagram)
- if you get a very high resistance reading, the heater element is likely broken. if so...
-- remove the 2 metal shields located horizontally across the evaporator coils (behind them are the two series-connected defrost heater elements)
-- visually inspect the elements - if they are discolored green or black, remove and inspect more closely (most likely they are blown, just like a light-bulb filament that shows black on the glass)
-- if you see nothing, remove them anyway (since high reading) and check connectors
-- replace them (likely only $30 to $75, depending on type)

- if coils seem ok, or if not suspect, check the defrost thermostat WHILE IT IS STILL IN A WORKING/COLD FREEZER.
- get the defrost thermostat into a coil chamber (other freezer or bucket of ice?) and check resistance using an ohmeter. It must be WELL-BELOW 40F to test it. When it is truly immersed in cold (as it would be in a working freezer), test the resistance. it should be 0-ohms when <<40F and some much higher resistance (>200KOhms) when > 40F.
- if not, replace it

-lastly, if neither the defrost heater elements are bad nor the defrost thermostat is bad, open up the defrost timer
-- the defrost timer is located in the fridge side, likely with the fridge thermostat knobs/controller
-- it is a 5-pin part that cannot be repaired. If all else is checked, most likely the defrost element is never coming on because the timer is not turning it on

Not defrosting
Removed existing and installed the new part. The hard part is reaching to the back of freezer as it not very wide and is farily deep. Hard to get to arms in at the same time.

The freezer section would work OK but the refrigerator stopped cooling
Tips from internet forums helped me figure out the problem: The defroster heaters were not working and the freezer side would frost up and prevent cold air from entering the refrigerator side. I removed the drawers, drawer slides, ice maker, then the back panel to expose the cooling coils. You can check the heaters for continuity before rempving them by disconnecting the two lead wiresonce you have the back panel removed. Not getting any continuity, I removed the old heaters after defrosting the coils. Removing the heaters was the most difficult part as they are a little "long" for where they fit, but with care it can be done, the same applies to installing the new heaters. I had to cut the connecting wire on one of the heaters to remove it, but got the new set installed OK. Works fine now, the bottom heater was defective, and since the are wired in series neither one will work independently. Everything works fine now, problem solved.

refrigator would cool properly
The most difficult part was determining what the problem was, was it the defrost timer, the themostat or the heater. Once I diagnosed the heater the ordering was easy. Installing it took about 30 minutes but waiting for the frig to cool to the point where the thermostat opened took a little longer than I thought. When I saw that orange glow from the heater I knew I saved myself a hundred buck.
