The evaporator coil behind the cover on the back wall inside the freezer will ice up under normal conditions. Every 8 to 10 hours for around 20 minutes the defrost timer (or in most newer models the electronic adaptive defrost control) will turn the defrost heater on to melt the built up ice. There is a defrost thermostat which prevents the heater from overheating the freezer by breaking the heater circuit when the temp reaches close to 32 degrees F. The entire cooling system shuts off during the defrost cycle and starts back when the timer advances through the cycle.

If this ice is not melted it will continue to build up until the air can’t flow over the coil to circulate the cold air through the freezer and into the fridge. The temperature change in the fridge is usually noticed first followed by the freezer.

If the defrost thermostat is bad, it can prevent the heater from coming on OR it won’t turn the heater off when it gets too warm. It is clamped to the evaporator coil at the top to sense the temp. If it appears to be misshapen it is bad.
With an ohm meter it should show continuity when cold and none when warm.
You can also bypass(disconnect the two wires plugged into it and twist them together) the thermostat to see if the heater comes on then. If it does then you know the thermostat is bad and needs replaced.

The defrost heater is located on the evaporator. It is in a tube which is at the bottom and can also go up the sides of the evaporator. On some types you can see a burnt spot if it’s bad. With an ohm meter it should show continuity from end to end when disconnected from the wiring in the freezer. You can also test the wiring for voltage when it’s in the defrost mode.

If you have a defrost timer you can test it. It can be located under the fridge behind the kick panel on the front. Some are in the fridge with the controls at the top. 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 because that means the timer is not running. If it doesn't, check the heater and defrost thermostat. Turn the timer again till everything starts back up to end the defrost cycle.

If you have an adaptive defrost control instead of a timer, replace it if the heater and thermostat test good. It is located in the fridge with the controls in some models and on the back in others. You can post your model number into one of several appliance parts sites on the internet and search for defrost components to find your parts.

Issue with Kenmore Refrigerator/Freezer


ok,1st check on fridge side toward upper back of the top and feel for air coming thru, and there is another one down possibly behind crisper .I had this same deal. Had to do total defrost,, put food in cooler,, theres two blower fans in these types of fridges,,one in the bottom back,, and one in the back of the frezzer,, I used an old hair dryer and let it blow warm to top interior of frezzer,, careful not to let any cords hang/drop in any water!!,ok once done dry out as much water as possible, turn fridge on set both controls to 4,when fridge kicks on do the feel test,, you may need to close the frezzer door, air should be felt near top inside of fridge,if so than shut fridge side and feel inside frezzer near bottom and air should be felt,, side-by-side need to circulate air from frezzer to fridge, then back to frezzer

I have a ffa90 futre fridge & bottom frezzer. the fridge is frezzing the food in the door & in the fridge. have tryed water in botles & they get ice on it .in the door the food frezzers so


Find where the supply air is coming into the fridge part. It comes from the freezer and could easily be supplying -18 air direct to the door. This would give you a 2 in the fridge but anything in the direct air path could freeze.

Vegetables keep freezing in the bin even though I have the temp control set at 1. The freezer compartment is also set at 1 and the freezer works fine at this setting.


Please VOTE FOR ME AND GIVE ME YOUR TESTIMONIAL IF POSSIBLE, IF THIS WAS HELPFUL
ITWILL BE MUCH APPRECIATED.
The cold control needs replacing. Thats the knob with the numbers that turn the Ref OFF and ON.
What I do is call my local Appliance Parts Store with my model no. They are extremely helpful .
Get freezer and ref thermometer. Ref is probably too cold.
Freezer should be 0 to 10 degrees. Ref 33 to 35

WATER SPLASHING IN FREEZER AT ICEMAKER
THE FILL TUBE IN BACK OF REFRIGERATOR CAN SLIP
AGAINST THE FILL RESERVOIR CAUSING A PARTIAL BLOCKAGE
OR BECOME CLOGGED WITH ICE.
REMOVE THE ICEMAKER AND INSPECT THE FILL TUBE.
RUN WATER IN TUBE TO ELININATE BLOCKAGE AND CHECK
TEMP IN FREEZER. IF TEMP IS BELOW 0 DEGREES, THATS
OVERKILL AND USUALLY A WASTE OF ELECTRICITY TO KEEP IT THAT COLD, NOT TO MENTION THE FILL TUBE FREEZING UP

My Kenmore refrigerator is not cooling properly. Freezer portion works fine but not refrigerator. Came on suddenly.


I had the same problem. The frezzer worked but the fridge was not getting cold. What I have learned is that the frezzer make the fridge cold, so if the frezzer is working then something is blocking the cold air to get into the fridge. Most likely ice. The air come in at the bottom of the inside of the fridge next to the frezzer. Pull everything out of the frezzer, then unscrew the plannel that runs along the back and you see if there is ice. If so turn frezzer off and dry out the frezzer. I used hot water.

Jenn-Air bottom freezer ice maker not working


I took the arm of the ice-making machine out of the slot and put it back in, pushing it snugly inside the slot, then raised and lowered it several times. Then, with the arm in the up (stop making ice) position, I felt inside the ice-making tray, where I noted there were ice cubes as well as a sheet of ice at the base of the ice-making tray. I poured approximately 24 oz. of hot tap water into the tray to melt the sheet of ice. I turned the freezer temp control to "warmer". I think the freezer temp setting was too cold, causing the ice maker to freeze the water before it could make cubes. I have a working ice maker again!

Fridge and freezer not getting cold


If it was layed down to move and not let sit for a while before using it again it would not work. Somtimes leaving in off and let it settle will straighten it out but not all time. The oil in the compressor get into the cooling lines and blockes the freon. Other than that, check the condenser coil which are near the compressor. They should be warm when the compressor is runnin. If they are not warm there is a compressor or freon problem.
