Hello and welcome.
It's clear that your self-defrost system has ceased to function. What needs to be determined is which part has failed. This depends what make and model you have, as there are some parts that are common failure parts on some models that almost never fail on another.

The basic defrost system consists of a heater (which is either a glass tube/radiant style or a calrod element), a timing device (either a simple clock with fixed defrost intervals or an electronic control that adapts to the environment and changes the frequency of the defrost cycles, and finally a cycle termination thermostat, which terminates the the cycle in the event the timing system fails or the temperature of the evaporator rises to a point where heat is no longer needed.
What I will do is force a defrost cycle to start and then check for amperage in the circuit with am amp probe. You often do not even need the amp-probe, because you can hear a sizzling and popping sound if the heater is energized on many units.

Without knowing what make and model, this is all the info I can provide at this time. I hope you found it useful.

Check your gasket on the freezer it may not be sealing properly. that is the main cause of the freezer compartment frosting up. also when you defrosted it did you otice if the drain line was clear and the water was going out of the freezer?

Freezer blowing air but getting warmer and stopped making ice. Fridg also seems to be warming up. no unusual noise.


If there is no cooling at all on the fridge section but the freezer works then it is confirmed that the compressor and gas pressure is OK. But if the freezer also gets warmer it can be failure of the auto defrost making the vents choked. Now shut off the fridge and leave it powered off while you clean and check the evaporator for frost. If frost is seen it is a good indication as the compressor is working with sufficient gas within.
Now after about 6 hours plug in the fridge to start. Observe cooling to happen in about one hour and ice to from under three hours.
Earlier make sure that the thermostat was set to normal mode for freezer and fridge.
However if ice forms in the freezer 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. Frost formation without defrosting could block the air flow and so shut the air passage to the fridge. Also the blower fan must work and if this is not working then the fan can be faulty. Also a fault on the control unit is a suspect to non functioning of any one of these components.
If defrost timer works but frost keeps forming check while the compressor shuts if the heaters are working, check continuity of the heaters.
So try this test using a multi-meter on the defrost timer and the thermostat and make your observations so that we come to the solution.

Our top mount Kenmore fridge (Model # 253.77872509) is frosting up in the freezer section. Have turned off & defrosted the freezer on several occasions - it works for a few weeks but then begins...


Hi,


Normally when frost build up occurs it's because warmer outside air is getting into the freezer and the moisture from that warm air cools and condensates then freezes into frost or ice. You either have a bad seal like the other listing states try leveling the front a little higher than the back. Or you may have an issue with the defrost heater, thermostat or timer. Do you have a light that comes on from time to time? If so you have an auto defrost unit. If there is no light you may not have a frost free freezer which means you will have to remove the frost manually.

Frost Buildup in Frost Free unit.


You will have to check the defrost timer to make sure it is turning if it is working properly and you are getting power to the defrost heating element below the freezer coil it should get hot if you have a 115volts or so to the element and it does not get hot then you have a bad element

Maytag side by side refrigerator - freezer side working ok but refrigerator side geeting warmer, have it all the way to the coldest setting 9 but it not getting colder seems to be holding around around 40...


you probably have a defrost problem. what you would see is frost on the rear panel of the freezer section at the back bottom.
this is common and you most likely need to replace the adaptive defrost control.
it is located inside the refr control box. you have to remove the cover and then the air housing with the lights attatched to it. once you have this housing down, then the "adc" is on the right rear and looks like a computer board.
dont try to figure out how it works, just replace it and then let the freezer warm up to remove the frost from the freezer coils. have a towel ready to pick up the excess water that will drip off the coil and onto the floor.it will take about 6 hours or so of being shut off.
after it has defrosted then turn the unit back on and with the new board it will start cooling properly again.

My freezer gets ice buidup


If it's on the surface of all the food it may be caused by leaky door gaskets or frequent door opening.


If it's on the back wall..
Your evaporator coils frost up in normal use and every eight hours or so the entire unit shuts down and the defrost heater comes on to melt the frost. This cycle last about 20 minutes. The melted frost drips into a drain pan and through a drain tube to the drain tray under the freezer/refrigerator where it's evaporated by the condenser fan.


Your drain tube may be stopped up with ice at the upper end because it drains too slow because it's stopped up at the lower end in the evaporator pan under the unit at the floor. It can get dust and mold in it. Once you get the ice out at the top a little pressure with a turkey baster will usually clear it out. Flushing it out with hot water and clorox may help.
Make sure it drains quick enough to prevent refreezing. . The drain should be located below the evaporator coils on the lower back of the freezer.
How to check everything
http://www.acmehowto.com/howto/appliance/refrigerator/refrigerator.php
If the evaporator coils behind the back panel of the freezer are icing up because of auto defrost failure that will stop the circulation of cold air and eventually affect the freezer too.

check defrost timer, defrost heater, defrost thermostat. In most newer models the timer has been replaced by an electronic control board. If the heater and thermostat are ok it’ll be the control.

You can turn the defrost timer till it clicks and everything shuts down. The heater should now come on. If it does, replace the timer. If it doesn't, check the heater and defrost thermostat. Turn the timer again till everything starts back up to end the defrost cycle.

Freezer compartment has frost buildup


This can be caused by the drain hole below freezer coil being blocked by ice. You MUST remove all ice in drain under freezer coil. Use turkey baster to squirt hot water into hole and use hairdryer to defrost. Possible defrost thermostat is defective. Unit never goes into defrost, ice forms on coil and in floor of freezer. After defrosting may work OK for a week or two but gradually gets warmer because ice is blocking ports where cool air gets to refrig. May also have water in refrig box. Can also be caused by defective defrost timer.

The freezer on top unit was keeping everything up top nice and cold, but the customer began to notice things in the fresh food section getting a little to warm. When the temperature selectors were adjusted to a colder setting, it seemed to help for a day or two, but then started getting warmer again. Sounding like a defrost problem, I paid this refrigerator a visit with hairdryer in hand, and parts in the van. Frost free refrigerators use a defrost heater to periodically assist with the melting of frost that builds up on the fins of the evaporator located in the freezer section. Frost forms each time the doors are opened to the unit, and the warmer, moist air from outside gets inside and heads toward the cold surface of the evaporator. As the frost continues to collect, the air passages in and around the evaporator start to close up and begin to prevent air circulation by the evaporator fan from the freezer to the fresh food section. As the cycle continues, the temperature in and around the evaporator will be cold, but the fresh food section will get warmer because warm air is not being exchanged with the colder air from above. The defrost sections of most units will consist of the same components. Namely, the heater itself, the bi-metal terminator, and the timer or defrost control. Each one of these components need to work properly for the defrost cycle to properly keep the unit frost free. On this unit, the timer could be advanced to begin a defrost cycle, but there was no current flow to the heater. After checking all connections and doing a quick resistance check of the circuit, I determined the bi-metal terminator had failed open. These bi-metal devices are used to prevent an overheating situation in the freezer section should the heater remain on to long. Once the trip temperature is reached, the bi-metal will open up a set of electrical contacts thus opening the circuit. Then when the unit cools back down to it's reset temperature, the contacts will again close, closing the circuit for the next defrost cycle. Because this bi-metal didn't reset, the circuit remained open and no defrosting took place. After using my trusty hairdryer and warm water squirt bottle to defrost the evaporator, I wired a new defrost terminator in line with the heater. With all the frost removed, the cold air started circulating again, and now everything within the fresh food section stays properly chilled.
