Easy repair
The repair was reasonably simple. The video provided by partselect.com was very helpful. I would suggest that one should also replace the defrost timer.

Fridge too warm. Coils frozen
I followed the videos supplied for the two parts. Everything looked exactly as he described in the videos. Took about an hour. Some patience required for the Adaptive Defrost Timer...just a bit tedious to get the cover off and the area released from the top of the fridge.
It started out as intermediate warming in the fridge...Then obviously it went out..getting the cover off in the fridge compartment was trying..after several attempts it slid right out..Guess I made just the right face..I heat gunned the frozen up cooler in the freezer to get to the heat coil and remove the built up ice...swapping the part
... Read mores was very easy...I watched the videos from the order page.. The temp rod was not turning the gear..I thought that the teeth on the rod were broken..It turned out that the gear had moved up and was not touching the rod.. I pushed it back in place and that took care of that problem.. I did not have to replace the rod..This sure is a great site to get your parts and the repair videos are the best..Thanks guys..Best advice...Take your time getting the fridge cover off... I got frustrated and walked away several times....When it did finally popped out it just slid right out easily..
Ordered parts on line and received next day via FEDEX! Great delivery time. Read on your website describing my problem. It came down to 2 possible parts which were both replaced.

Freezer wasn't cooling and refrigerator side was not working.
I didn't know if I would be successful with this repair because the repairman had estimated $485.00 to fix the problem. This seemed like a serious problem to me and I was dubious as to whether or not I could fix it on my own. Well, I watched the video and re-watched carefully noting the steps. I followed the video to the letter and had

We are able to do these repairs probably better than the repairmen! Thanks for the help PartSelect. I will ALWAYS go to your site if any appliance breaks down in my home. See how much money I saved? And the part arrived in 2 days; faster than a repairman!

Automatic defrost was not functioning correctly, had to manually defrost every week
I watched your video, took notes, ordered the parts and installed them. Refrigerator works great. Might not have needed all three components, however I live in a remote part of Alaska so I ordered the works. Thinking that the other parts were also well used also and probably close to failure. THE REFRIGERATOR IS WORKING LIKE NEW. Your

I followed the video on Part Select which covered everything in detail. The longest time was to defrost the coils. After removing the cover, part of the coils were iced up. The actual repair only took about 10 minutes. I had found my old heater element had bent so it was no longer heating the coils. I also replaced the Adaptive Defrost Ti

Refrigerator not cooling, freezer thawing but cold.
I removed the back lower panel within the freezer compartment. The cooling fan which draws cold air from the evaporator unit was functioning fine. I then unplugged the unit. The evaporator unit was frozen in a block of ice. I removed all food contents from both the freezer and the refrigerator, moving them to a back-up refrigerator.
... Read moreI then allowed the radiator to thaw completely overnight. Upon restarting the unit it became cold within an hour thus I new the compressor was fine. I surmised it must be a defrost issue. I then unconnected the defrost heater and thermostat assembly. The device was easy to remove. I then routed the wire of the new assembly on the side of the evaporator unit and clipped the thermostat back onto the cooper feed, plugged the unit into the connection. Next I turned my attention to replacing the adaptive defrost timer. In the top of the refrigerator compartment, I removed the plastic shroud, by sliding back and pushing the plastic clips in. I took out 4 screws holding the unit to the ceiling of the refrigerator. Slowly lowering this, I could see the adaptive defrost timer in the right rear corner. I simply unplugged the unit and replaced with a new unit. I replaced both items although I am unsure which was not working. Refrigerator is working fine now.
Did a resistance check on the old defrost heater. It was out of the specified resistance. Removed cover over cooling coils in freezer. Removed old defrost heater/thermostat assembly with a pair of needle nosed pliers. Plugged in new assembly, and installed new thermostat, and retaining clip for heater assembly.

6 months ago i replaced the defrost heater & thermostat assy, because it was shorting on the metal fin of the evaporator and the freezer wasn't defrosting. Now the freezer stopped defrosting again but the heater assy looks fine. How do i test the heater for continuity and what resistive value am i supposed to see on the ohm meter? Or do i test for voltage? What sort of test do i perform? According to what i've seen so far, it's either the heater assy, or the adaptive defrost board that causes this problem. What do you think?
For model number WP61006199
Hi Rick,
Thank you for your question. Before you test the part for continuity, please unplug the appliance from the electrical outlet or turn the circuit breaker off and then remove the heater from the refrigerator. A continuity test will not work on some defrost heaters, because the ohms reading may be too high to register on a continuity test. If you have an auto ranging multimeter, set it to the ohms setting. If you have a manual ranging multimeter, set it to the lowest ohms setting. Place one of each of the probes on each of the heater's wires or terminals. You should get an approximate reading of 10 to 150 ohms. If the display on the meter does not change or if your ohms reading is far off from that then you have a bad heating element. Where there is a thermostat attached to the heater you will need to make sure that it has cooled down below its closing temperature before doing the ohms test. I hope this helps. Thank you and have a great day!

Ice maker door seems to open and close properly. I get frost build up between the shut and the door?
For model number MZD2766GES
Hi Jim,
Thank you for the question, Sounds like the door might be bent or warped enough to let a bit of air through and it is causing the frost build up. I suggest replacing the Ice Dispenser Solenoid and Door Kit.
Hope this helps!
My freezer/frig runs, then stops and almost thaws, then runs again. I went into the top refrig area and took the cover of the controls and when i move some items, the compressors starts, but usually stops. It's this reason that i do not think it's the defrost heater/thermostat. Compressor looks clean. The freezer has half frozen food and the frig not cold. Ideas?
For model number MZD2766GES
Hello Ken, Thank you for the question. I suggest testing the Run Capacitor,PartSelect Number PS11743364. This part helps the compressor kick on and off while maintaining a constant temperature to keep things frozen in your freezer. If you are noticing temperature issues with your refrigerator or freezer, the run capacitor may need replacing.Hope this helps, good luck with this repair!

My freezer working fine but ref.Is not cooling at all
For model number mzd2766ge
Hello Francis and thank you for writing.
It certainly sounds like it could be a faulty defrost heater and thermostat PS11743281 and/or a faulty run capacitor PS11743364, you should check for signs of damage, and replace if necessary. We hope this helps. Please contact us anytime if you require further assistance.
