Freezer coil icing up solid and blocking cold air flow into refrigerator.
Checked the heating element in the freezer and it read 0.22 OHMS (I assumed it was good) and ordered the adaptive defrost board. Followed the instructions for installation (very clear and easy). Refrigerator has been running for two weeks and the temperature has remained a consistent 35'F. -- Woo-hoo problem solved.

Coils froze up in freezer side.
This was second time I had to replace the Defrost Board. Last time was very difficult due to not understanding the instructions. This time I watched the video a couple of times, then went thru the steps in the video. It was much easier this time.

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.

I had ice building up inside on the bottom of my freezer and a buzzing sound coming from inside the fridge towards the top right
After doing some reading on the internet, someone had mentioned that the drain hole in the freezer might be clogged. Of course, I did not know where to look exactly. I heard the buzzing sound one day and opened the fridge. I placed my hand right under the area that was concealed and isolated roughly (by touch) where the noise was coming from. I started to pull off the cover where the water filter was and started unscrewing with a nutdriver and screwdriver about 5 to 6 screws until I loosened things enough to get the cover off partially. I felt a part and also found a diagram of the fridge. The part felt hot to the touch. After looking at the diagram, I realized that it was the adaptive defrost timer making the noise. I decided to order the part because it was worth it to try fixing and while everything was open, I figured I'd change all the light bulbs as well. Luckily, I have another fridge in my basement and moved all food to that fridge. I unplugged the troublesome fridge and let it defrost. I also removed all the shelves from the freezer and fridge so they could be cleaned. I did not take any pictures, so it took me a while to put them back when it was time. I also located the evaporator in the freezer section. I had to unscrew the back cover to get to it. I noticed that that area behind the cover was also iced up, so I found the source. Sure enough, the drain plug was clogged and water started to accumulate. I unscrewed the evaporator from the top and sheet metal pan from the bottom and removed the pan. I opened up the bottom rear of the fridge so I could located the drain hose and drip tray it fed into. I noticed the pan was totally dry. I removed the hose from the drain plug and stuck an awl from the bottom of the plug going into the freezer and finally dislodged whatever dust and grime was in there and the water started coming through. I then took a can of compressed air and shot it into the drain plug. I also shot compressed air onto the condenser and fan to clean things up a bit (make it a little easier for the condenser to release its heat). I reinstalled the drain hose and ran some white vinegar from the inside. It flowed nicely into the pan. I dried everything up. I also decided that this was the perfect time to clean the fridge and all of its components on the inside (it is a side by side - so both the freezer and fridge area). This took some time, especially disassembling the drawers. At the end, after replacing all bulbs except the 2 small ones by the control area, I removed the old adaptive defrost timer and it took me a good 15 minutes to line up the new one. The new one is bigger than the old one and also encased. I had a hard time getting the plug on since it was hard to see. I was putting this in while the control section was hanging down at a 35 degree slant. Room was limited. I managed to connect the plug and then had to position the ADT so it would fit in its spot perfectly. Only then was I able to put the screws that hold it there. It needed to sit perfectly in there, which it did. I changed the 2 bulbs and put everything back together. Of course, in the middle of all this, I had a video on your site explaining how to remove the control panel and install the ADT. Pretty funny stuff. Pretty much did it the same way. Getting the cover off is a little difficult because the back left corner gets caught even when you pull down on it. It took me a while to realize where the cover was getting stuck. Nevertheless, I finished the repair and the fridge seems to be working great for now. I am keeping my I on it. I haven't heard any buzzing noises and no ice has built up on the bottom of the freezer yet. In fact, this is the quitest my fridge had been for a long time. Hopefully, it was last a few more years. Knock on wood.

Freezer icing up, but not cooling in refrigerator
I followed the video that is posted on the site. It went exactly as it described, and was very straight forward and fairly easy to do.

Grinding, chirping noise
I followed the video you provided. It was extremely helpful. It was actually easier than I expected after watching the video. The cover removal looked scary but the part is extremely flexible (flimsy). Removing the old part required removing the 2 hex head screws. After installing the new part, I had trouble getting the screws back in. After several failed attempts ( the screws kept falling out), I removed the part again and realized that the new part was not tapped to receive the screws. I installed it without the screws and it works just fine. Suggest you check to see if the holes in the two holes are tapped before you install it. It will save time and aggrevation.

Refrigerator section was getting warm, due to frosted coil in freezer section.
I actully did two replacements at one time. I replaced the defrost heater and thermostat plus the adaptive defrost. I chose to replace both as I had no way of diagnosing which was the problem (excecept for the heater of course). Firstly make sure you keep track of where the screws come from when you disassemble the plastic and metal panels. Once the coil is defrosted in the freezer, it is easy to remove the panel covering the coil, then it is very easy to remove and replace the thermostat and heater. Just be careful to route the wires the same way as the origional configuration and do not force anything near the coil evaporator coil as it is only aluminum. The adaptive defrost component is simple to change out, the hard part is to CAREFULLY remove the plastic panels under which is located the adaptive defrost. Again, remember where the screws go and how the parts go together. The video for changing out the adaptive defrost is extremely helpful. Patience, patience and more patience is required when fooling with the bits of plastic. Allow plenty of time to do the project and do not rush. All of the parts go together like a jig saw puzzle but are very logically assembeled. Good Luck, I saved about $300 in doing these fixes my self.

fridge and freezer was warm
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 parts 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..

The refrigerator was worming up while the freezer was at zero.
I called a local Appilance Co and the responding repair man stated Oh ! a Maytag that is a big problem. This unit has a Mother Board in the top of the Refrig. that is costly and very difficult to replace. When questioned he stated that the part had to be ordered and would not be in for (5) days at a repair cost of replacement and labor or $296.00 The best advice he gave me was to put this unit to the curb as it was shot. I asked him about this so called Mother Board ie (The Brain) and he said they ordered this on line BINGO !I contact you service department spoke with a very fine and concerened rep. and he advised me correctly and the part was ordered. Wow! delivery with in 24 hours with out and special pricing just regular ground Fed. Ex. I watched the Video you company had posted of the removal and install of the new 3 x 3 1/2 by 3/4 in. plug in part and with the video insturctions is was more then simple. Total time less then 10 minutes. Thanks ever so much for everything. By the way Mr. Repair man service was charge was $79.95 for 5 minutes of bad advice. Total cost of repair with you was $64.00 the repairmans advice not priceless but a lesson learned. So for all those persons out there take time to investigate on this web site before waisting your money needlessly. This was a great experience with this company, video and sales rep. Keep up the good work, Oh another thing with is the boyfriend writing at did the above but a female would had done the same and as we know they usualy have more ability when it comes to time consuming work.

Evaporated completely frosted over how can i tell if is the defrost heater/thermo, or adaptive defrost board, thanks
For model number Maytag mzd2766ges

Hi Frank, Thank you for your question. I would suggest testing your defrost heart and thermostat with a multi meter to be sure that they are both working. If they are both working then you may have to replace your board. Good luck with your repair.

Is this an oem part . Does it read Maytag on the board . The serial number is 10900931zm revision 10
For model number MZD2766GEW
PartSelect logo
Hello Marty, thank you for your question. All parts that we sell are OEM parts. They come directly from the manufacturer and would be the same parts you would receive if ordered through them. The board may not read Maytag on it as Maytag is now a Whirlpool brand. Sometimes the parts are manufactured with part number tags on them, sometimes they are not. However, as previously mentioned, all parts we sell are OEM parts. I hope this answers your question!

I already replaced the heater element and my coils still frost over after several days. Can you tell me what the next part I should try to remedy this problem?
For model number JSD2789GES
PartSelect logo
Hi John,Thank you for the question. I suggest testing the defrost thermostat that attaches to the heater. 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. If the thermostat is good, I suggest replacing the Adaptive Defrost Board. Hope this helps!

Hello. My freezer is perfect. But the fridge is not cold enough. It's 46f. And the adjusting level doesn't seem to work. Because no matter where i put it at, the temperature is not changing. What do i need to check?
For model number JCB2389DRS

Hi Jaekwan, Thank you for your question. I would suggest testing your defrost heater and defrost thermostat. You should also take a look at your run capacitor as well. You may want to also take a look at your evaporator fan motor as well. I hope that helps. Good luck with your repair.
