Maytag MDZ2766GE* Not cooling sufficiently

Fridge and freezer recently started to lose thier cool. Unit was close to the wall and I moved out hoping to find that it was a heat exchange problem. House is not ACed and has gotten much warmer in the last few days. Fridge and freezer seem to have cooled slightly since the move from the wall but certainly not enough to protect. Freezer is keeping stuff marginally frozen. Would guess fridge to be in the 50's or so with switches set to full cold. Fan and air exchange in back seem to be working. Compressor is hot. No obstructions of built up fuzz/dust/lint to be found.

Is there any great likelihood that the system needs charging (134a) and it that user serviceable?

Will go to the coils next to check for icing and will look for any airflow restrictions but would be so grateful for any help in solving this problem. Appreciate it so much. Thanks.

Defrost the fridge, take everything out of freezer and turn off for at least a day, check the drain is clear after defrosted and try again, if it happens again you may need a new defrost heater of timer.

Be sure if you get into the refrigerator disconnect the power!

I posted this earlier below for another problem. you need to make sure anytime you fix a problem like this in any refrig you defrost all ice. I found just stting there the ice will remain for 10 hours in the box. Why I don't know but I saw it happen.
The control could still be the problem if you did not replace the whole bboard. There is a way to check the heater with a meter but I don't remember the value. It has to have Ohms if not it is broken.
I had the same problem and I knew it was the refrigerator. You have to order the control board that controls the fan assy in the freezer. It has an inherent problem with others I see. But don't attempt to change it yourself. There is tricks to it and if you don't do it right you will break more things. I saw the tech broke some tabs and it is stupid way to design something unless you plan to get more business this method.

The control board sits in front of the water filter in the refrigerator. Inside the Temperature control housing cover.

Additionally, you have to take all the frozen food out and defrost manually the fan area and the subsequent ducts to clear it all out. Otherwise, you will have the same problem again. If it breaks and it will. It causes the ice to build up to point you will not get fan movement or airflow. This flow keeps the Icebox from freezing up and causes the air to flow to the refrigerator side.
They make these things so it is harder for DIY to do it.
But they are really simple! At least most of it.
Contrary to popular belief Ice is a good insulator. Once it builds up, no heat transfer takes place because of the inefficiencies it blocks the airflow and etc.

It is my opinion and I stand by it.

I bought many Maytag items and it suppose to have a great reputation. I have now started to look at other providers.

I find these companies are getting cheaper and instead the quality is going down.

So buyer beware not all have across the board quality it depends on the series, the price and the manufacturer.

Oh well another lesson learned.

Here is another problem when using a ice maker unit do not always use the ice crusher. I found that out. The motor that drives the ice crusher is matted with metal to plastic then metal again in the Ice Holder unit.
Guess what, it jams sometimes and it puts great pressure on the ice maker holder unit.

Where the metal meets the plastic is the weakness. It breaks because of in my opinion weak design
The two plastic nibs meeting with the metal motor drive square "U" connector breaks the plastic and eventually you have to get the plastic replaced. I think if I have to order that little part will end up buying the whole Ice holder assembly.
One direction for crushed ice the other direction it turns for solid ice cubes.

I guess I will use the solid Ice cube method until I figure what to do.

Any parts for it replacing the plastic hookup out there?

Good Luck!

SOURCE: maytag mff2557hew fridge not cooling. Freezer ok.

Sounds like the Freezer Fan is wearing out or is worn out. This fan problem is very hard to detect. The reason is that when the motor is starting to wear out the fan will spin, but at a much lower rpm. This is enough to keep the freezer cold. but will not ciculate enough air thru the freezer and the refrigerator to prevent freezer from and refrigerator from cooler. The cost to repair/replace this fan is a minimum of $300.00

Testimonial: "Your solution was right on the mark! The fan was spinning but not fast enough (according to my repair guy). Thanks again!"

Some fridge freezers take the cold air from the freezer and moves it into the fridge via small duct in the back of the inside of the fridge and freezer . Empty frige and freezer , take plug ouy of wall and carefully remove involved panels taking note of any mechanical valves and order for reassembly. Clean and clear all airways and check for any blockages . Over loading of freezer can also obstruct airways . Whilst you are doing this you will allow a good defrost time for fridge and freezer airways . Hope this helps

Its defrost problem.--------- When you open the freezer door, then ice starts getting defrosted, because outside temperature is warm and due to that inside ice gets bit melted.--------- -------------- The working procedure of this unit is as follows: --- The compressor starts then it cools the freezer section. When the freezer reaches its cooling level the defrost cycle starts functioning. In this cycle the fan in the freezer section starts running and the cool air in the freezer section is passed to the fridge section and the fridge section gets cold. The air from freezer to refrigerator passes from the section, in that section the damper is located. ----------- The damper is operated by a motor.Its a complete damper assembly with motor included in it.--The damper has door.Which closes and open with the help of motor.In your case the damper door is blocked by ice, because your refrigerator is not defrosting.But when you open the freezer door, the inside ice gets bit warm and it starts melting and this lets the fridge section get cool.------------------- In this case you will have to manually defrost the ice and inspect, if the problem solves.For manual defrost procedure, click the link below:-------- Click this below for more detail:--- ----------- This will help.Thanks.Helpmech.

Sounds like a defrost problem, is there ice on the back wall of the freezer? If so the defrost system has failed. The most common repair is a Part# 67004757 defrost thermostat and adaptive defrost board Part# 67004704. Even with the parts in your hand, you will need to de-ice the freezer to replace the thermostat in the freezer section, then unplug unit to replace the adaptive defrost board located in the controls of the refrigerator section. Normally it can take about an hour to complete.
Good Luck

Oncce the fridge was shut off and left for a while the cooling had come back . If frost is seen it is a good indication as the compressor is working with sufficient gas within.
If after about 6 hours you observe cooling it is possible that the defrost timer is faulty.
Earlier make sure that the thermostat was set to normal mode for freezer and fridge.
However if Ice forms then observe the fridge for about 24 hours for cooling to continue and the fridge to cut off . If not the auto defrost timer, or the thermostat must be checked.
If defrost timer works but frost keeps forming check while the compressor shuts if the heaters are working, check continuity of the heaters.
replace the defrost timer, heater or thermostat one you have confirmed to eliminate one by one.

Maytag MSD2651HES fridge not cooling freezer works find

Sounds like a defrost problem. Check to see if there is any frost buildup in the back wall of the freezer. If so, it is not defrosting as it should.
  • possible causes:
  1. bad defrost timer
  2. bad defrost heater (in freezer)
  3. bad thermo switch in freezer
If you don’t know what these are then unplug the machine and let the ice melt in the freezer overnight with the door open. Then try it the next day, if is cooling fine then you need to have a service person replace one of the above items.

Maytag fridge

Without knowing the type of fridge(side by side, freezer on top etc.) all I can offer is this: Somewhere between the freezer and the fridge there's an opening thermostatically controlled to transfer cold air from freezer to the fridge. Most have a fan to move the air. So either the fan (if so equipped) stopped, and need to replace, or opening is stuck closed, or plugged.
If freezer is working fine, this is the only problem I can think of.
Hope this helps
