Normal 0 MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman"; mso-fareast-font-family:"Times New Roman";} DEFROST PROBLEM
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.

Fridge fine, freezer defrosting


What is the model number? I believe you may have a problem with a defrost heater, defrost thermostat or defrost control. Will need to manually defrost the fridge by placing hot water in the freezer area with the door shut and the power to the fridge disconnected for a few hours. Then we can try to find the cause

Fridge not getting cold...but freezer is working


the fridge gets its cold air from the freezer fan blowing it through small air passages between the freezer and fridge. when you adjust the temperature in the fridge you are increasing/decreasing the amount of air being let into the fridge. Two common problems that could cause the freezer to freeze but not the fridge getting cool is the freezer coil is frooze like a ice cube blocking the air going to the fridge or freezer fan is not working could be bad or froze up due to too much ice. If fan works after manually defrosting problem could be in the auto defrost mechanism. If fan don't work after manual defrost replace fan. Manual defrost by putting a pot of very hot water in freezer with door closed change water foten until defrosted.

The dam thing is only two years old, just started defrosting, all functions is normal , stoped working,started defrosting


there is a hole in most fridges where you can see the defrost timer you can manually turn it if it gets stuck. and put it back to operation mode for most fridges its in the fridge top looks like a screw driver would fit in it all plastic. Read manual to find it but you can manually bring it out of defrost mode by turing this hidden switch.

Got a hotpoint ffa97, freezer was still cold and no alarm had gone off to say that that there had been a power cut yet the fridge temp had risen enough to curdle milk??\r\ntemp gauge was still showing...


Milk can sometimes curdle in a working fridge. But it does sound like your defrost system may be malfunctioning. Can you empty your freezer and inspect the defrost system behind the air circulator fan?

I know that defrost elements sometimes go bad and the controllers can pop too. You should check your operators manual and see how to put the fridge into manual defrost. *(it usually involves turning the fridge light on and off by hand. See if the freezer drains during manual defrost. If you have lots of food that dries out in a frost free unit the moisture contains a lot of contaminants that can plug the defrost drain. Which leads to a blocked air passage between the freezer and fridge sides.

You might want to get a small backup fridge for a while to run this down.
Or just use up the food in your fridge before running the tests.

Good luck and be careful.

How do i defrost my 4.cu ft manual defrost fridge?


Turn it off or unplug it, put a big towel inside to catch the water, afterward, wipe off the water and turn it back on. Some manual defrost fridge has a defrost button, you can push it once and it will defrost it for you.
