Fridge side not cooling no cold air blowing that side


If easy to remove back panel of the freezer section of your fridge do it. If not then dont go for it. Rather look at the type of fridge you got. If thats a digitilozed panel in front then you can manually defrost the fridge throgh that.
If you can remove the back panel anyhow , test the thermostat. If you got a multimeter just unplug the thermostat while its is still frozen and test the two ends of the wires ( if that thermo is not frozen enough it will gove you wrong read). In digital multimeter it will read above 1 if that thermo is ok. If not then it will read all the time 1. You can replace that faulty thermo with any universal thermo available anywhere.
if that thermo is ok then check the continuty of heater rod. If thats also ok then chck the defrost timer. However, for digital panel the timer is embeded with it it. So you need to change the entire panel with less than 50 percent success in solving the problem. I would rather keep the fridge as a gadget that requires manual defrost every 1 week or so. Cheers.

Freezer works, warm air in fridge.


If the ice/frost buildup is fairly thick and only on the back freezer panel then you have a defrost problem. Most likely the defrost thermostat is bad. It would be hard to explain how to test this in writing but there is a tech sheet underneath the fridge behind the grill on the r/f. It is in plastic which is stuck to the fridge. This tech sheet will tell you how to put it into diagnostic mode. First take the back panel of the freezer off (may need to get frost off first). Should be four 1/4" screws in each corner of the panel to remove. Will need to remove racks, door (should just lift off), and ice maker first. Remove vent in center of freezer panel by pushing up little tab in the center of the vent and using a screw driver to pop it loose on each side of the vent. Then remove thermistor cover on right hand side of panel. Remove (by pushing thru) ice maker plug. Once the panel is off put the fridge into defrost by the instructions on the tech sheet. If it goes into defrost (heater will get hot) then the main control board is bad. If not shut the doors to reset, defrost evaporator with a hair dryer and remove the defrost thermostat. It is a little metal round piece with two wires coming out of it and just clips onto the evaporator. Cut the two wires coming out of the thermostat, strip them back and splice them together. Now put it into defrost again. If the heater comes on then you know the thermostat is bad. Diagnostics mode can also test all functions i.e. condensor motor, compressor, evaporator fan, and thermistors. With all of that said, if it isn't a thick frost buildup the evaporator fan motor may be bad which is the most common repair on this model. It sits just behind the vent in the center of the freezer panel. Let me know what you find.

How to Replace a Thermostat in a Fridge?


If there cooling and defrosting problem in your fridge. Also over cooling or not getting cooling properly problem. Then the problem relates to thermostat.
The procedure to replace the thermostat is as follows: ---
1) First of all unplug the fridge/refrigerator unit from electrical outlet for complete safety.
2) In top freezer and bottom refrigerator model units. The thermostat is located at the rear of freezer side. But in some units its located in the bottom of the refrigerator floor panel.
3) In side-by-side refrigerator the thermostat is located at the back of the freezer side.
4) To remove the thermostat you will have to remove the screws from the icemaker section located in the freezer section.
5) After the screws from the freezer’s inner section are removed. The inside panel will get loose and come out.
6) Many a time the screws are hidden under rubber type butches. So its bit hard to locate the screws. So check out properly that all the screws in the inner section are properly removed.
7) After the inside panel of the freezer section is removed. You will see the thermostat. It has wires connected to its terminals. Be care full that you don’t pull out any wires. They are very thin and delicate wires.
8) The wires are connected to the thermostat by a connector. So slowly remove the connector from the thermostat using a needle nose pier. Take care you don’t put any force while doing this. It’s very delicate but not very hard to do.
9) After the wires are removed. Remove the screws holding the thermostat .In some models the thermostat is screwed to evaporator coil tubes. In that cases take care you don’t damage the tube while removing the screws holding the thermostat.
10) Before removing the thermostat take care you note down the position of old thermostat. so after the old thermostat is removed out by removing the screws. Place the new thermostat in the same exact position.
11) Refit all the parts which you removed while removing the old thermostat in reverse method. Take care you don’t miss any part fitting.
This will help. Thanks.

How do I replace the thermostat switch on a Zanussi ZCE 7701CH? I have removed the screws for the side panels at the rear but cannot access the screws for the side panels at the front. The Product No...


Hi,the problem you are encountering is as a result of the fact that the thermostat which regulates the cooling temperature in the fridge/freezer is bad hence there is no regulation of the cooling temperature in the fridge/freezer section, hence the food in the fridge freezes up.

The solution is to replace the thermostat of the unit,here is how you go about it;

1.You have to disconnect the fridge from the power source.
2.Locate the thermostat at the bottom of the unit,at the top left corner above the condenser.
3.Now you need to locate the wire ends or wire harness and unplug them.
4.Replace the thermostat,reconnect it back,put the back cover back and you have completed the job.

Take care of yourself

Fridge freezer - freezer working but fridge not. red warm light is on


Hello,

If refrigerator is not cooling properly can be due to a defrost timer, which is causing the fridge to go into defrost cycle. Usually it takes 45-60 minutes for refrigerator to come out of defrost cycle. If the timer goes bad then it will not come out of defrost cycle and can result in this kind of issues. It can also occur due to defrost thermostat, it allows current to pass through it at temperatures of 20 to 30 degrees Fahrenheit and prevents current from passing through it at 40 to 60 degrees. This is difficult to test, though, because it takes a prolonged, very-cold temperature to turn it on. The defrost thermostat is snapped onto the top portion of the evaporator. The thermostat sends temperature information to the processor. The defrost heater must be replaced when replacing the thermostat.

1. Remove the lower fan duct work from the evaporator cover.
2. Remove the 1/4-in. evaporator cover screws and remove the evaporator cover.
3. Disconnect the defrost thermostat wiring connector.
4. Remove the defrost thermostat from the evaporator.

I hope the above helps.......

Good luck.

Not getting cold


Hello,

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 behind the cold control cover. Once you locate the defrost timer, slowly turn the screw like wheel 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 ohm test the defrost heater for continuity or volt 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, join the 2 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* and defrost thermostat. If the defrost timer seems "hot" to the touch or is noisy ( like a ticking or screeching noise )...replace it.

Would also appreciate if you could provide us the model number of your fridge so that if the above solution does not resolve your issue would look into the matter specific to your type of model.

I am sure this solution would help you to resolve the issue.

God Bless

Freezer works fine but fridge has lost its temperature.


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

..
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.
