When the fridge freezes everything, usually means that there is a problem in the self-defrost system. You may even have damaged door gaskets. When you open the freezer door, you also let in a blast of warm, often humid air. This moisture usually freezes onto the evaporator coils immediately.

Self-defrost freezers are supposed to self-defrost themselves. Every 6-12 hours they turn off the compressor for a few minutes. A defrost heater then turns on to melt any frost build-up on these coils, which allows the frost and ice to melt, then it drains off to the pan underneath. Unfortunately, though, when a component fails, too much frost can build up on the evaporator coils. With no air flow over the coils, cooling in the freezer compartment becomes almost non-existent.

You can manually defrost your freezer by turning it off for 24-48 hours and turn it back on to see if it begins to work properly. If your freezer now works the way it’s supposed to, test the three other components in the self-defrosting system, the defrost heater, the defrost thermostat, or the defrost timer.

You can visually inspect some defrost heaters to see if there is a break. If it looks physically broken, then it needs to be replaced. Otherwise, check the defrost heater for continuity.

The defrost thermostat, which is just a bi-metal switch, lets current pass through at factory set temperatures. It also prevents current from passing through at the temperatures set by the factory. The set temperatures for the defrost thermostat vary from manufacturer to manufacturer.

You can test the defrost timer by manually advancing to the defrost cycle. You can usually manually advance this timer with a screwdriver. Insert the screwdriver into the advancement pinion and turn clockwise a 1/4 to 3/8′s of a turn. The timer should advance out of the defrost cycle in less than an hour.

If, after testing these components, it still does not cool properly, there may be a problem with the refrigerant level and you will need to contact a professional appliance repair person.

Thank you and good luck!

Are you sure the "Intensive cooling" function is not active?

    Sorry, that function is on the FAB32 model. In your case it may be just a food-related problem, meaning that you put in food with too much moist and that moist eventually freezes, but because those aliments don't have protective coating, then the water spreads and freezes all over the other containers. So, be sure to cover up all water-rich foods with protective foils.

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.

Fridge freezing up


Check the fridge sensor. On my Hoover HNMF2805AL80 f/f, first I replaced control module - still freezing.
Have just replaced cheap fridge temperature sensor. Part No. 97061619. Trouble is you have to cut into insulation at back of fridge to replace. I just plugged in sensor & placed inside fridge at back at the bottom - so far so good, only lettuce freezing now, everything else v. cold but not frozen. :)

GE refrig side by side 7-8 yrs old will not freeze frig not cold


Generally, This would be a sealed system problem. An inefficient compressor or low refrigerant. If you notice a build up of frost on the freezer panel it might be a defrost problem, but, I am leaning towards an inefficient compressor.

Freezer not freezing enough and fridge not cold enough


Hello Scott, remove the food from the freezer side and remove the rear freezer panel. You will see a coil and it should be completely frosted over. If not then you have a sealed system issue. If it is froze solid in frost where you cannot even see the coil, then you have a defrost issue. You should have a little frost on all the coil, the defrost is what clears the frost so the evap fan motor can circulate the air thru out the unit. If frost is good, push the light door switch to start the fan. If it isn't running check for 120 volts. If it has voltage, but not running, replace the motor. Hope this helps.

GE bottem freeze- not cooling


It is not so much the freezer motor icing up but the drain trough that takes the water from defrost down to the pan.Possibly your drain trough is clogged and needs dethawing and cleaning.
