It sounds as if the freezer coils and vent stack are frozen solid. This usually requires
removing the back panel in the freezer compartment and defrosting carefully with
a hair dryer. (If this becomes frozen it blocks off the fan/vent that feeds cold air down to
the fresh food compartment) Make sure to unplug unit before servicing as you will need
to unplug the fan to remove the back panel.
While doing this check the defrost termination thermostat (a small device attached to
the tube with two wires coming out of it). The black plastic ones sometimes come apart
and fail.
Once defrosted put everything back together and test.
Hope this helps.

Refrigerator doesn t get cold


If your refrigerator is frost free and been running for a year or two then here is the solution.
Why would you need to defrost a frost-free freezer? Because they do sometimes get frosted up! This is especially common if the door gets left open for long periods without being noticed, then shut again, thereby trapping lots of moist air in the freezer, which can only come out as frost. The problem is that if their defrosting cycles don't manage to cure their problems they get frosted up at the back, out of sight. If your freezer seems to be struggling to keep things frozen but is otherwise working normally you should consider defrosting it before concluding it is broken.

I have found the best way to defrost my not quite frost free fridge-freezer is to empty the freezer compartment contents into the fridge and switch it off overnight, leaving the fridge door shut and the freezer door open. By stacking all the frozen food together as tightly as possible, ideally wrapped in something to help insulate them (such as newspapers) they stay cold for a long time. In the morning I get in my scruffy clothes and wipe up the puddles caused by the visible frost in the freezer and any puddles formed underneath the appliance. However this is only half the story. To ensure all the frosting has been removed from the hidden parts of the appliance I get my hair dryer and blast warm air into all appropriate crevices from inside the appliance and from behind it.

Top shelves in freezer not freezing food. Also no ice from ice maker. Seems cold air has stopped coming out of top vent


We had the same problem with our refrigerator just yesterday. Defrosting (even tho frost-free) cleared up the airflow problem-- If it's frost-free, when it defrosts enough to allow air flow, the automatic defrost can take over. Cause was stored food blocking the vent between the freezer and lower part of fridge.

My freezer (upper) works but my fridge (lower) doesn't. There's nothing clogging the vent. What could be the problem? Thank u!



My fridge is running but not cold enough: Start out with the easy stuff first...make sure the lights go out when you close the door(s), make sure the doors are closing properly and the gaskets are closing fully and are not torn or ripped. Check to make sure the evaporator fan in the freezer is working, this fan blows the cold air around. If the fan is not working, possible bad fan motor - check for power to the f


The most common fridge "not cooling" problem is a frost free failure. Remove the access panel in the freezer section to expose the evaporator coils. If the coils in the freezer section get plugged up with frost, this frost will block the evaporator fan motor from blowing the cold air around. The fan blade can also hit this frost and either become noisy or stop altogether. Locating the defrost timer can be tricky....they are often hidden behind the back bottom corners of the fridge at the bottom, in the last few years the timers have been located in the ceiling of the fresh food section, and some are behind the cold control cover. Once you locate the defrost timer, slowly turn the screw likeknob in the middle of the defrost timer with a straight screwdriver until the fridge shuts off. You are now in defrost. If the defrost heater (s) comes on now, replace the defrost timer and defrost thermostat. If the heater(s) does not come on, you can continuity test the defrost heater for continuity or test for 120 volts to the heater(s). If you have no power to the defrost heater (s) you can also bypass the defrost thermostat to see if the defrost heater will come on, jumper the wires together to bypass the defrost thermostat. If the heater now comes on, replace the defrost timer and defrost thermostat. If the heater itself is bad, defrost the fridge with a hair dryer, replace the defrost heater (s) and defrost thermostat. If the defrost timer seems "hot" to the touch or is noisy ( like a ticking or screeching noise )...replace it.

Side by side thermostat set low seems like it runs a lot more than it use to freezer and fridge are boyh cold


Check your coils underneath the fridge to be sure they are clean.
Check your condensor fan (bottom rear of fridge) to make sure it is blowing air freely.
Make sure you have a good supply in the freezer, All of your cooling comes from the freezer section and a mostly empty freezer will result in more frequent running as ther is not enough stock to help maintian and hold freezing temperatures.
Check your freezer section to make sure there is no visible frost on the back wall of the freezer (down low on the panels behind and slightly above the lowest freezer basket. If you see frost starting to develop it means you have a defrost issue starting and will want to adress it rather quickly. Either a problem with the defrost control board (inside fridge/freezer control compartment) or the defrost thermostat (behind the freezer back panel on top of the evaporator coils).
Hopefully this helps!

We have had a repairman come in 2 times now and the problem still seems unresolved. The freezer wan't defrosting so the fridge was not cold enough(mid 50s temperature on a laser thermometer. First visit...


Check for frost on the lower back wall of the freezer again.
You may have either a defective defrost terminating thermostat (located in freezer at top of evaporator coils behind lower back panel of freezer) this should read closed when testing for continuity with an ohm-meter. Another possibility is the defrost heater itself could be the issue but pretty rare on this model (the heater is a calrod style element like in an oven located at the bottom of the coils).
Good luck!

How to check everything

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.


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.

The fridge gets its cold air from the freezer through a vent(damper) 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 .

Door problem-The lower hinge on each door may have a door closing cam. It raises the door up ¼ inch when opening and this assist in closing the door. If it’s wore out and doesn’t work the door may not seal and the gasket can be damaged. Watch the operation of the door to see if it rises up when opened.

6343ed3.jpg The problem is ice build up on the back wall. The noise you hear is the fan blades hitting the ice. On the back wall water gets trapped, it then builds up over time, and a big ball of ice forms and blocks the fan. Take off the back wall, defrost the build up and cut the insulation off as above. The water will no longer get trapped and the problem will not come back.
