MZD2766GEB Maytag Refrigerator - Instructions

Took out all shelves and racks. Pulled out plastic cover. Removed screws holding control unit. Removed unit and accresses defrost circuit board. Replacement is in a cover. One screw would not engage so did not put it back in. Reefer was cold within hour of start and is now 1 week after. Unit would start out cold and then warm up before replacement.
Other parts were snap in furnishings that had become damaged with use.

I called a repair man from a pretty large name to come out and take a look. He found out in about 10 minutes that it was a bad capacitor. The quote he gave me was $75 for the part and $175 labor. I tried my best not to laugh and tell him no thank you. He did have to charge me for him to show up, which was only $98.
So I used what he told(minus the "scrap it") and opened it back up. Although he had left wires everywhere and the broken pieces laying inside, I thought it was enough for me to order the part. PartSelect was very easy to navigate and ordering was a breeze. Took about 4 days to get the part and I ordered in the X-mas craze. Fixed it in about 15 minutes.

First I hired a repairman to fix it who charged $125 to defrost the cooling coils then said the defrost heater would need to be replaced for $125+labor. He had the wrong part and was going to charge me >3x the price it would have been from Partselect.com too. I figure I saved a minimum of $250 vs having him do the work then charge me yet again for the right part.

Should have just done this myself from the start and saved another $125. Information about the cause, how to test and what parts would be needed were all easy to find online once I actually searched.

Unplugged fridge.

Using diagrams from PartSelect.com and other information online anb defrosted coils with hair-dryer. (This requires removing two screws in back of freezer compartment using nut-driver to remove the panels covering coils... literally a two minute job to expose coils!)

Then found and tested defrost heater.
Defrost heater was fine. Per information online problem then had to be Adaptive Frost Control (ADA) circuit board.

In refrigerator compartment:
1) Removed top housing cover (covers lights, temp controls, etc.) This required removing a single screw (with nut-driver) attaching it to back and depressing two locking tabs near the back on either side. Slide it forward and down. The only tricky part of this repair is getting the locking tabs positioned correctly to get the plastic cover off. I did break the left one although it cover is still firmly in place in this case.)

2) Removed entire assembly from roof of fridge. involves loosening two large headed screws above lights and removing two hex-head screws with nut-driver above either side of temp controls. Next slide slightly to the right to disengage the two large-headed screws (or remove them completely... it seemed easier to just leave them in place.) Dropped front end of control assembly down.

3) Opened plastic box surrounding ADA and pried open locking tab holding it to wiring. Connected new board and set ADA assembly back in place.

4) Put everything back together.

Plugged fridge in and all was well. Exposed the coils again a few days later and they were not frosted up at all.

Total time to replace the ADA was about 20 minutes. Total time for everything including defrosting coils, testing, replacing parts, etc. was an hour max.

These so called factory trained techs, at least the ones that looked at my fridge don't know jack. I explained my problem, they replaced T-Stat refridge side, onother time they replaced door gasket, still not cold enough, found your website,
got all the answers. Ordered and installed,defrost
heater and T stat assy and adaptive defrost control. Remove shelves freezer side, remove evaporator cover 1/4" nutdriver ,defrost with hair
drier, unsnap elec. connector and relaced part.
The ADC, removed screws mounted on roofside
was able to lower plastic panel enough to unplug
the ADC, it just laid there, removed and replaced.
Don't know which part was bad, but I do know that
they are interconnected, at this point I din't care to defrost manually which I did for the last 7 months.
Thanks for your guidance. USMC Ross

Chronically faulty electronic board in upper right rear of refrigerator compartment - in Maytag and Jenn-Air. Unplug unit. Remove freezer food to ice chest. Remove baskets and shelves, ice hopper and rear lower panel to expose evaporater fins. Defrost with hair dryer and allow all moisture to dry. Then in refrigerator, remove top shelf food. Carefully remove the upper assembly cover by working the plastic down and slide forward to unhook from rear slide attachments - one on each side. This is the hard part of repair.

Then remove screws from rear wall and just behind the lamps to release the whole control assembly. In the rear right corner is the bad board. Unplug and replace with new board. Reassemble the fridge and freezer. Replug unit.

Confirmed the condenser fan was the problem when I noted it was not running when the compressor was on. Removed 3 mounting screws, unpluggede the fan. Removed and replaced the mounted flange(3 screws) and remounted. Plugged in fan and it started running.

Thanks for the diagrams and quick delivery. This is the second repair on appliances I have made with your parts and probably saved $300-400 in service calls.

This was very easy. I removed all the shelves in the freezer compartment. I removed two nutscrews to remove the back wall. Then I removed the little radiator looking part by removing two more nutscrews. I unplugged the old thermostat assembly and installed the new one exactly like I removed it, then I reversed the procedure to put it all back together. Very easy my wife could have done it. ThANKS!! to Parts Select for the help of all the blogs I read before doing the job.

Removed the ice bucket from the freezer. Removed the single screw on the left side with a nut driver, then lift and pull the tray toward you...there is a wiring harness in back of the tray that I had to unplug...easy, pinch the sides of the plastic connector and it disconnects..and the tray came out of the refrigerator...and the cussing started. Since the threaded yoke was stripped it could not be unscrewed from the motor shaft...I took my trusty Dremel Tool and cut the shaft off so the yoke could be separated from the motor shaft and the motor could be removed from the plastic housing. From here on it was a piece of cake...install the new motor and screw the new yoke onto the motor shaft... I think it has a left handed thread, like the old propane bottles used to have..slide the tray back in, reconnect the wiring harness (it only plugs in one way), make sure the tray is sitting on the 4 side supports, put the single screw on the left side and you are done....put the ice bucket back in and flip the bail down and you should be back on business....!!

This was not a difficult project at all.
I removed the ice bin and then unplugged the wiring hareness.
With the old enclosure removed I first removed all of the screws holding the solenoid (look at the way it is mounted before removing all screws). I then removed the drive motor for the ice crusher/dispenser.
The yoke on the drive motor has a left hand thread.
Grip the motor shaft behind the yoke with a thin pair of channel locks or pliers and tap on the yoke in a counterclockwise direction with a small hammer to loosen and remove the yoke.
I then reattached the motor and reinstalled the yoke and then reinstalled the solenoid.
It was a bit of a trick to plug in the wiring harness, but if you use a small mirror you can do it with ease.
Be sure and align the drive motor yoke with the couple on the ice bin at a 90 degrees from the yoke on the motor. Also make sure the dispensing mechanisim on the ice bin moves freely. If not remove all ice from the bin and locate where the ice is jammed and remove it.
Trust me this will save the new enclosure you just installed.

I Removed the two wires from the old relay. I Then pulled the old relay off the compressor. Next, I had to get the overload seperated from the old burnt relay, which took some care not to break. The old relay and overload is in a plastic compartment. Then I followed the directions that came with the new relay. The only confusion came with getting the two wires back onto the terminals of the new relay, mainly because the old relay was burnt so badly I didn't have any idea how it was originally wired. I crossed the two wires on the terminals of the relay. The compressor would click off and on, but would not start blowing cold air. I swapped the wires on the terminals and it started working immediately.

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. I 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.

Upon careful inspection, I found that the dispenser also would occasionally fail to shut off when dispensing whole or crushed ice, which led me to think that the problem was in the dispenser actuator rather than in the water solenoid or fountain switch control board. To inspect the actuator mechanism, I shut off power to the refrigerator, removed the escutcheon mounting screws, the escutcheon, the cable from the fountain switch control board, and finally the fountain bracket assembly. There was a small amount of hard water scale on the back of the actuator pad, but no groove in the plastic part of the pad that actuates the switch. I replaced the pad and switch (1 screw) and reassembled the dispenser. The dispenser no longer sticks and shuts off normally.

followed the instructions provided and that's it!

I don't know anything about repairing a refrigerator - I'm a computer tech. I noticed that the outside of the fridge was warm to the touch and the inside was not getting as cold as it should. I took the lower back panel behind the fridge off and noticed that the fan was not spinning. The local parts dealers did not have the condenser fan motor that was needed but they did say that they do go bad. I decided to order one from PartSelect.com and do it myself. Using a 1/4 inch nut driver and a flat head screw driver to pry the old motor out of the casing, I got the job done in about an hour or so. It's a relativly easy job. Besides the ouside panel screws, there's 3 screws on the inside near the fan blades you have to reach in to get. Pop out the whole assembly, unscrew the nut that holds the blades on and pry out the old motor and replace.. Try it yourself and save a couple hundred bucks!

UNPLUG YOUR FRIDGE BEFORE YOU START> First I removed the shroud covering the lights and controls in the top of the refrigerator side. This was the hardest part, actually. Their are two indentations on the back of the cover and it is really hard to pull that cover off. Anyhow, once you do that, their are two screws, one by each light bulb in the top of the fridge that need to be removed. Their are also three hex head screws that need to be removed, two in the front corners of the assembly, one in the center, back of the fridge. Take those out and the whole assembly drops down. In the back right had corner of the assembly is the adaptive defrost control. Unplug it and set it aside. Plug the new one in. Put everything back together and you are back in business.
