Maytag fridge getting too cold

Remove the housing that covers the evaporator inside the fresh food section and remove any ice or sludge that may be blocking the defrost drain below that evaporator. Insure no ice or water is touching the defrost sensor for that section. This is a common problem that Samsung has with it's dual evaporator refrigerators. With that drain blocked the problem will only become worse.Thanks Sea Breeze

Hello,

Insufficient cooling is a fridge repair job that you can do without the help of a professional. Often the fridge has a frost-free failure, or the compressor is faulty but there are many other reasons for a fridge not cooling properly.
Step 1 - Find the Problem

Your first job is to locate the source of the problem. Consider each of the following:

* Gaskets - Make sure the gaskets/seals are not torn and are sealing properly.
* Evaporator fan - Make sure it is working. If it is now working you may have a problem with the fan motor. Check for power to the motor and also examine the fan switches around the door (not all fridges have these switches).
* Air damper - Sometimes the air damper will not open up to allow the cold air from the freezer part to blow into the fridge section.
* Condenser coils - Check to see that the condenser coils don't have a dust build-up and that the condenser motor is working.
* Compressor - Make sure your compressor is working with on and off clicking noises.

Step 2 - Frost-Free Failure

This is the most common cooling problem in fridges. Expose the evaporator coils by accessing the panel in the freezer section. The coils in the freezer section can sometimes get clogged up with frost. This can stop the evaporator fan motor from blowing cold air around, or cause the fan to hit it and stop, or become noisy. The defrost timer can be a bit tricky to find but it is usually located behind the back bottom corners of the fridge, although they can sometimes be found in the ceiling of the fresh food section, or behind the cold control cover.
Step 3 - Find the Timer

When you find the timer, turn the wheel-like screw slowly with a screwdriver until the fridge shuts off. The refrigerator is now defrosting. If you find that the fridge starts now, you will need to replace the defrost thermostat and the defrost timer.
Step 4 - Volt Test

If the heaters do not come on, use a volt meter to ohm test the defrost heater or volt test for 120 volts to the heater. You can bypass the defrost thermostat if you haven't got power to the defrost heater to check if the defrost heater will come on. To bypass the thermostat, join the two wires together. Replace the defrost thermostat and the defrost timer if the heater comes on now.

If there is a ticking or squealing noise in the defrost timer, or it seems hot to touch, replace it.

Many fridges have and inline fuse on both sides of the defrost heater. You will need to replace the whole heater if one of those fuses blows. Check these fuses with a volt meter if the defrost heater doesn't work.

A quick check if you have a cooling problem is to inspect the evaporator coils. If there is a build up of white snow on the coils, this indicates a frost free problem; if there is balled ice on part of the coils with the rest bare, this indicates a system problem, like a problem with the pumping compressor.
Take care in solving the problem....

Either, the defrost timmer has had it, or the freezer defrost element has failed, the element is the most common cause of this type of problem. You have ice build-up in the freezer cores because it cant defrost, all frostfree units rely on cold air from the freezer to blow into the fridge, if the freezer cores become blocked, air can not pass to the fridge side. I bet you, if you left the unit off for 2 days to defrost totally,,,,with the doors open...then plugged it back in, it would work like new for 2 weeks.
Timmer or defrost element needs to be replaced...do not fall for the trick that the fridge mech. has to take it away, you tell him that this is the problem and you will save yourself ALOT of cash.

Dont forget to vote for the solution...regards Russ

Click Here for your user manual=> MQU1556AEW.pdf The settings for defrost should come automatically every 12 hours. You may test the defrost timer that appears to be behind the kick plate at base and front bottom of refrigerator by removing the kick plate first and using a flathead screwdriver turn slowly clockwise until compressor stops. After a few minutes you should be able to hear a crackling noise or sizzle by opening the door and listening. Leave the timer like that for up to 35 minutes and if the freezer does not start on its own the the timer is not working properly and will need replaced. Click Here=> MQU1556AEW Unit parts number 15 in photo is defrost timer. The defrost timer is part number=> 4357124 Defrost Timer Check for air leaks around door seal as this will cause the same symptoms. If by chance the defrost timer works and the defrost does not then let me know here or here=> Appliance 911 The only other parts are the defrost heater number 16 in photo MQU1556AEW Unit Parts and part number for defrost heater is Click Here=> 8201749 If you change the defrost heater it is always good to replace the defrost thermostat number 18 in MQU1556AEW Unit Parts The defrost thermostat is part number=> 1-81801-001 The most likely problem is the defrost timer but I needed to cover every possibility. If you have questions please feel free to ask, Thanks, Sea Breeze

the clicking sound is normal it sounds like valve operating or you may have the water pressure up to hgh for the unit. for your second problem is the fan operating inthe fridge this stops the cold air to transfer from the freezer, also check the operation of the damper this is the flap the controls the amount of air into the fridge this is uasualy controled by a by metalic thermostat or motor. thirdly which mostly common is the defrost heater is not working signs are frozer evaperator in freezer and air duct the checks are defrost timer, heater element terminatinion thermostat and someunits have thermofuses goodluck

Your tech doesn't have the issue completely fixed. You have a defrost issue and defrosting manually is just the start to resolving your issue. You have to diagnose why it fails to defrost. You have a heater, control thermostat,frost sensor, etc. to check for a failure after defrosting it. Get someone that knows how to complete the job right!

It is possible the refrigerator has gone into defrost and stuck there. I'm not sure what features to tell you to look for but you probably have a defrost timer or something called Adaptive Defrost Control board. They are the part that most likely causes the problem. If you could send me the model number found on the door frame on most refrigerators I would help you locate the parts.. Anyway when they stop cooling like that it reminds me of a defrost timer caught in the defrost cycle and the only way to locate it and turn it clockwise may get you going until the defrost timer can be replaced. I have seen thermostats do the same thing. Thanks Sea Breeze

Check for complete model number for me to look up the correct refrigerator. Possible the defrost timer or defrost board. Could also be the defrost element or other problem. Will try to help you if you can find the model number, Let me know, Thanks Sea Breeze

The thermostat should be a close circuit when requesting cold temps. or when asking the compressor to come on. The exterior surface on some freezers warm when asking for cold inside. Yours has a condenser coil on the back and that should warm when cooling. If compressor is runningit should be wrm if no freon has leaked from freezer somewhere.
The defrost timer should rotate clockwise during the day and give approx. 3 defrost daily or about every 8 hours. Until the thermostat is resolved and asks for a closed circuit the compressor will not come on. Unplug freezer from outlet,remove thermostat wires, then turn the thermostat to its coldest setting and check again. If no closed circuit the thermostat will need replaced first. Hope this has helped you, Sea Breeze

                     

 I am trying to contact Leibherr; I see that production is located in the United Kingdom. I have found an office located in New York. I’m sure this is not helpful and your freezer is very expensive and I will try to get technical information (if they will allow me access). Sounds as if the defrost timer is not working and that would be the first thing I would look at if I could see the wiring diagram. If it is a common defrost it will be a timer that cycles every 8 hours. If it’s a digital defrost with circuit board I won’t be able to locate it until I get a response from Leibherr. The problem could also be in the defrost element. Here is the link that I have found.  Let me know anything or information you have obtain since the beginning of your search that will help me help you get the problem solved, Thank You, Sea Breeze HVAC
