Go to the back of your fridge and listen to it carefully. See if you will hear a hizzing sound. If you hear a hizzing sound, then there's a leak in your fridge. The reason why the temp is dropping because the refrigerant is decreasing. You need to contact a pro to check where the leak is coming from and have him reload the refrigerant of what we call the freon.

Thank you and good luck!

Hi,

I'm pretty sure that the unit has a fault that will need to be looked at professionally but can you discount the following:

1. Have you put too much fresh food into the freezer without

activating SuperFrost?

2. Does the door close properly?

3. Is the appliance sufficiently well ventilated?

4. Clear ventilation grilles if necessary.

5. Is the ambient temperature too hot?

6. Has the appliance been opened too often or left open too

long?


If you want to have a go yourself you will need to find a service manual. There are quite a few things that could cause the fault you have.

My fridge suddenly stopped cooling, if i restart it, the freezer start getting cold, may even make ice, but it all quit after few days ar few hours. Any clue?


If the capillary tubes are visible on the back, take a hammer and lightly tap on them about every half inch all the way around to break up the grunge.

Sub zero 532 fridge is not cooling porperly but freezer is fine


Top of Form

If there is no cooling at all on the fridge section but the freezer works then it is confirmed that the compressor and gas pressure is OK. Now shut off the fridge and leave it powered off while you clean and check the evaporator for frost. If frost is seen it is a good indication as the compressor is working with sufficient gas within.
Now after about 6 hours plug in the fridge to start. Observe cooling to happen in about one hour and ice to from under three hours.
Earlier make sure that the thermostat was set to normal mode for freezer and fridge.
However if ice forms in the freezer then observe the fridge for about 24 hours for cooling to continue and the fridge to cut off . If not the auto defrost timer, or the thermostat must be checked. Frost formation without defrosting could block the air flow and so shut the air passage to the fridge. Also the blower fan must work and if this is not working then the fan can be faulty. Also a fault on the control unit is a suspect to non functioning of any one of these components.
If defrost timer works but frost keeps forming check while the compressor shuts if the heaters are working, check continuity of the heaters.
So try this test using a multi-meter on the defrost timer and the thermostat and make your observations so that we come to the solution.

Hello,

When the refrigerator side is getting too cold this is because the control of the compressor has gone bad in some way...

There a few different things that could cause the unit to lose control over the temperature of the fridge side.

If your refrigerator has a damper door that opens and closes to allow cold air to move to the fridge side the damper linkage or the damper motor may have broken or gone bad.

The coils in your fridge may have frozen over and now the air does not move at all so then the ice builds up and can freeze parts of the fridge side.

The thermostat has gone bad and so now the compressor runs continually. This will not be noticed readily on the freezer side but will show up quickly on the fridge side.

Many newer model refrigerators use an electronic sensor or thermistor to read the temperature and supply the info for the circuit board and often a digital readout.

So, here is how I would go about troubleshooting this problem.

Check the coils for ice, defrost the coils with a heat gun or hairdryer, then check for the reason why they iced over. Defrost control or defrost timer bad? Evaporator fan bad?

Check the damper door to see if it is stuck in the open position. If it is then check the motor and the linkage.

Check to see if the refrigeration unit will shut down if the thermostat or digital setting is turned up to a higher temperature. If it continues to run then find the cause and fix it. It may be a bad thermostat, sensor, or control board.

Sometimes with a change is weather to a cooler climate this will be enough to also affect the inside temperatures. Make sure that a bit of adjustment in the thermostat or setting of the temperature will not solve your problem very simply.

I hope the above helps.

Good luck.

My Panasonic refrigerator NR-B420T is not cooling, however the freezer part still cooling.

Since there is cooling on the freezer the fault can be the defrost timer. So shut off the fridge and leave it off while you clean and check the evaporator for frost. If frost is seen it is a good indication as the compressor is working with sufficient gas within.

If defrost timer works but frost keeps forming check while the compressor shuts if the heaters are working, check continuity of the heaters.
So try this test from the outside and make your observations so that we come to the solution.

I have a Teka A-FCI340 fridge/freezer. The fridge is too cold and freezes items put into it. No matter how I turn the temperature control dial it still seems to be too cold.


I had the exact same problem with the same model and mine was just 3 years old. My problems started when I defrosted the freezer. I spent 75gbp on an engineer who told me that I had probably 'spooked' the fridge when I defrosted the freezer, that this particular model of fridge wasn't designed to last longer than 2 years.

I would recommend you check the door is shutting properly (check the screws at the top, it might be just slightly out of alignment).... I turned the whole unit off for over 2 days to allow absolutely everything to defrost (both inside and on the back of it)... within 30 minutes of turning it on, the back of my fridge was already frosted over.

Engineer told me not to waste money calling them out again, and to buy another one...

If it's American, the temperature probably reads as fahrenheit. If so, 20 degrees F is 12 degrees F below freezing which converts to only -6.67 degrees Celsius.

Domestic freezers should be set to -17 degrees Celsius (= 0 degrees F), so the beeper is warning you that the freezer compartment is far too warm. If it's working correctly and has the temperature control set correctly, then it should achieve the correct temperature if you leave it for 24 hours and do not open the door nor try to use the ice dispenser. If the freezer is full of unfrozen items and so has to cool those down as well, then it may take even longer to reach the correct operating temperature.

Te operating manual for your appliance will tell you how to set the temperature correctly and whether it's possible to select between fahrenheit and Celsius scales. Most models allow you to set an override on the beep alarm as well. I cannot guide you on this without knowing the exact Samsung model.

Please take a moment to rate my reply.

Siemens fridge freezer kg30u694gb has droped temperature from -23 to -4 is that normal also alarm is on


No. The freezer's ideal temperature is -18 and if this has dropped it can be due to many issues.
It can be the gas pressure, the pumping of the compressor if there is no coling even after switching off for several hours.
If cooling returns after several hours it can be auto defrost timer, thermostat or poor defrost heating

Shut off fridgge and power on after some 6 hours. If the temperature in freezer goes to below -5( ideal -18) then the system is working fine. If the freezing stops after several hours then it is possible that the thermostat is not working or the auto defrost timer is not shutting off the system,
However is there is no cooling then the compressor or gas pressure is down.

it is possible that your fridge has developed a snag in its cooling system. what could be done from your end will be to first of all switch off the fridge for at least 8 hours. allow it to totally defrost. then switch on to see if the cooling returns. if so reduce the thermostat to 7 degrees and check. if the cooling returns then you will need to check for frosting inside due to failure of the thermostat or the auto defroster. if there is still no cooling then your gas has leaked, failureof the compressor, failue of the valves in the compressor could be suspected. Probe with these inputs. Good day
