Fridge/freezer freezing up-and no fanor air circulation:

first check the defrost terminator thermostat it may have gone out. Thus not allowing the heating element to melt the ice.?

AT TIMES The fan usually stops workingAND CAN MAKE FUNNY NOISES AS WELLdue to ice obstruction when the defrost terminator has gone out and u get ice build up? u can check the terminator with a multi meter for continuity but do not check at room temperature. stick the terminator in cup of ice water for 20 minutes then check it for continuity, should be closed when cold and open at room temperature.

May also need to check thedefrost timer,The defrost timer is usually found behind the front grill "toe kick" of the refrigerator.Or in the fridge compartment near middle top section.

u can get by and test manually by placing a small screw driver into the tiny slot or hole underneath the timer and turn slowly clockwise till u hear 1 click. this will engageurdefrost cycle in about 15 minutes u should be able to come back and feel the heat in freezer as it melts the ice providingurterminator is not bad?

Another way to test it is with a multi meter. Remove timer it from fridge and you will see 4 prongs numbered 2,1,4,3 in that order. Placeurmeter prong on prong 1 & 3 (if your fridge has a capacitor wired in series with the windings, then u check for micro fares rather than OHMS) If u cannot confirm this test, still try the next.

Takeurmeter prong and connect to prong 1 & 4, it should read resistance or ohms ( closed) now remove prongs and place on prong 1 & 2, this should now read infinity or open (no ohms) now take a small screwdriver place it in the tiny hole or slot under the timer. Turn it clockwise slowly till u hear 1 click. Nowur1& 2 should read closed ( showing ohms or resistance) now place meter prongs on 1 & 4 and you it should now show open ( or no resistance - no ohms) this is how u knowurtimer is good, Remember when testing for ohms ADJUST meter to use a high ohms rating in the thousands as the resistance is very high in OHMS. And adjusting to low ohms rating may give a false reading or not show the proper resistance..

Another item to check with a meter is theheating elementitself. Located under the evaporator coils. It should show continuity or resistance OHMS WHEN TESTED AT BOTH ENDS OF THE PRONGS .

Lastly check thecold control thermostatwith a meter for both OHMS and volts ( VOLTS is a live test with fridge plugged in so be careful) It must show 110 volts. An open or thermostat that reads infinity will not allow the proper cooling and defrosting cycles to operate and may in fact stop anything from happening as if there is no power to the unit?

ALSO CHECK THE AIR FLOW VENT SYSTEMand THERMISTORSAt times it can get stuck to far closed or open. Some units feature a digital electric adjusting vent system while others are manually set. Check for any ice build up or other obstruction in the vent damper, see if u can manually open or close it. Some times when u have the settings set to the highest it closes off one area while allowing to much cold air flow to the other area!

THERMISTORS in the freezer and fridge section for continuity OHMS and for amount of OHMS current being putout. In most models around 1300( give or take 150 ohms) ohms is required

SOURCE: Kenmore refrigerator won't cool, but freezer does.

by closing that small door you are starving the refrig of cold air . you should be getting a heavy whisper of air through that door. place all controls in the middle position, close the freezer door and check for airflow through that vent.

Make sure the thermister is attached firmly to the fins in the back. The boards on a Norcold can be reset a service center familiar with this process is your best bet. It takes disconecting the board and then shorting it out best to leave it to some one who is familiar.

SOURCE: Kenmore Elite bottom freezer refridgerator

I just went through this with my refridgerator and actually posted one of the questions. Here is what I found ........

In the freezer compartment behind the panel there is an evaporator fan which pulls cold air from the freezer and pushes it up into the refrridgerator compartment. If the fan is not working it is one of three things.. 1) there is so much frost in the fan area the fan blade is stopped and cannot push the cold air into the refridgerator compartment or the air channel is blocked. 2) there is no electricity going to the fan (usually tied to the door switch of the refirdgerator compartment, and 3) the motor is dead and will have to be replaced.

Solution to #1 - defrost but there is another problem in the "frost-free" part of the system which must be addressed or the frost will return and it will happen again in the future.

Solution #2 - check to see there is power to the fan. (most are 110VAC but some are 100VDC. Use a meter and check)

Solution #3 - If there is power, the motor is dead. Replace the motor. Be aware that AC and DC motors are different and replace per manufacture's specifications.

The same control PCB is used for the refrigerator and freezer, but the setting of the PCB is 1 if fitted in a freezer and 0 if fitted in a refrigerator. Does anybody know how to change this setting?


Look for a jumper much like the kind you find on Hard drives and computer motherboards. If there is one. there will be indicators printed on the board.

The Refrigerator's Freezer is not working but the fridge is, what is wrong?


You probably have one compressor that cools the freezer section and the refrigerator section. Usually the freezer gets cooled directly with the cooling coils. A fan blows cool air to the refrigerator section. The air flow to the refrigerator may be modulated with some time of "air door". What you have written says to me, is that the fans and air doors are working but there is enough cold for the refrigerator but not enough for the freezer.

Here is what I would do:
  1. Put a thermometer in the refrigerator and in the freezer.
  2. Be sure the coils underneath or behind the refrigerator are clean. If they are very dirty, clean them.
  3. Keep the doors shut for at least 12 hours and then read the thermometers and write down the temperatures.
  4. Freezer temperature
    1. If the freezer has started freezing again, you fixed it by cleaning the coils
    2. .If the freezer temperature is between 0 deg F and 32 deg F, consider putting the food in a cooler and packing in some dry ice to try and save it.
    3. If the freezer is warmer than 32 deg f, throw away the food.
    4. Doctors and hospitals are pretty expensive. I would throw away the food no matter what the thermometer read.
  5. Look inside the freezer at the cooling coils. See if they are ice coated or not.
    1. If the freezer is above 0 deg F, and the coils are ice covered, the defrost control is not working. Unplug the refrigerator for 12 hours and let the ice melt. (Keep the doors shut.) Then, plug in the refrigerator for 12 hours and check the temperature like in step 3.
    2. If the freezer is above 0 deg F, and the coils are NOT ice covered, the compressor is not working.
  6. Call the service technician. When she comes out show her the temperatures and tell her what you found out about the ice on the coils.
Good luck

What is the normal fluctuation range of a top freezer in a freeze-refrig combo? That is if I set the temperature of the freezer a 0 F, at what temperature should the freezer come on to keep the air i


Hello Richard;

My name is Peter. I am a retired field service refrigeration technician.

The normal range for a freezer is -2 to +2 Deg. F.

The normal range for the fresh food section is 35 to 40 Deg. F.

If you set your freezer at 0 Deg. F. it will stay at 0 Deg. F.
When the freezer temperature drops below 0, your compressor will kick in to bring the freezer back to 0 Deg. F.

Lg lfx25960st not cool enough


1. What are your controls (freezer & refer) set at?
LG recommends 0 deg for the freezer & 37 deg for the refer.

2. The way a modern refrigerator works is, the freezer is cooled directly and cold air then is blown into the refer section. The incoming vents in a French door LG are at the back, top. Return are at the bottom. Make certain that nothing is blocking these vents and than the refer has good air circulation.

3. Vacuum the coils at the back of the refer. A large build up of dust, dirt, animal hair etc. will affect efficiency.

Freezer won't stay cold. it remains at about 10 deg, not 0 deg like it is set for. fridge seems to be warmer than set point also, but not as extreme. GE model PDW22SISRSS.


Three possible reasons, you have a main control board inside the fresh food section that may be defective. It's hiding behind the controls, then the defrost heater and defrost thermostat inside the freezer. I think I found the board replacement. we just need to look at the board with power unplugged to fridge. We will go from there if you need my help please double check the model number. I found 2 similar numbers but not yours. I will walk you through this if you want, let me know, Thanks Sea Breeze

Refrigerator cools, but not cool enough, even with temp adjustment turned to coldest setting. Freezer only gets down to 0. Fridge at 44 degrees


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.

The fridge gets its cold air from the freezer through a vent between the freezer and fridge.The fan in the freezer blows air through it. There is a flap you adjust with the fridge temp. control. Make sure it's opening and closing when you adjust the fridge temp ..


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.
