Question about Sub-Zero 690 Side by Side Refrigerator

1 Answer

Overheating condensors both freezer and refrigerator conpressors reach temperature of 160 to 170 degrees, as measured by a wood stove thermometer.  Heat is transferred the bar between the fridge and freezer which it how the problem became evident.  Temperature of both units is above normal, 45 for fridge and 10 for freezer.  The condenser is clean and the fan is working.  The unit is 20 years old; no major problems to speak of.

    Thank you.......Is it normal that both compressors would go out at the same time in that the fridge and freezer operate on separate ones.  Or, is a thermostat somewhere in the system failing.  After reset, i.e. turning both sides off, and then on again, the units behaved normally for a few days, and then the problem began again.  Also this is a Sub Zero 532 and 20 years old.

Bad compressor. Anytime a compressor on anything gets to hot to touch that is a sign that the piston is applying to much pressure to work which in return causes the compressor to go bad if not caught right awya

    It is possible for both to go bad at the same time. Give it a shot on replacing the T-STat that may just solve this problem as I did not know that you already tried reseting the system

My magic chef mini fridge jumps from 55 to 49 degrees and it's set at 41. What can the problem be?


The first and simplest cause of unstable temperature readings occurs whenever people open the door, which almost immediately causes a change in your refrigerator/freezer's internal temperature. In this case, the temperature recorded by the electronic monitoring system is often comparable to a conventional thermometer located in the cabinet. What personnel often don't realize is that typical mercury thermometers have response times measured in minutes, meaning that it can take 5-10 minutes for the temperature shown on the thermometer to stabilize at the new value after a rapid temperature change.

A second source of temperature variation arises from the normal cycling of the compressor used to cool the refrigerator/freezer. Again, if the temperature displayed by your thermometer is being compared to the temperature reported by your electronic monitoring system, the response time of the thermometer may be masking the actual temperature fluctuations in the cabinet.

The final cause is due to electrical noise in the temperature monitoring system. This can often be identified from the temperature data in the form of random jumps in temperature from 0.5 to 5 degrees or more happening over a very short time period (such as seconds). The most common cause of electrical noise is the placement of wires from the sensor.

Hi,

If the refrigerator is not cold enough then please check the following and also click on the blue coloured links for more info.


How To Check the Temperature1x1.gif In most refrigerator freezers, the refrigerator gets its cold from the freezer. The evaporator fan circulates air over the coils in the freezer and cold air circulates into the refrigerator through vents. If the vents are blocked or closed, then the fridge will not get cold enough but the freezer will. If neither is cold enough, then the number of possibilities increases.
Lowering the freezer temperature will increase the cooling cycle activity. Setting the refrigerator temperature may have little affect on the cooling cycles because it simply changes the vent opening size. Decreasing the fridge temperature opens the vents more and increases air circulation from the freezer.
The temperature can be adjusted using the controls found inside the refrigerator or freezer. The ideal freezer temperature is about 0 to 5 degrees (F) and about 38 degrees (F) for the fridge.
Measure the temperature by placing a cup of water with a cooking thermometer into the refrigerator for about 2 hours or more. To test the freezer, substitute alcohol or cooking oil.


Goodluck,

I cannot adjust the fridge/freezer temperature


Hi, there

Purchase an appliance thermometer that is specifically made for refrigerators and freezers. These special thermometers were made to withstand cold temperatures and provide an accurate reading when exposed to such temperatures.

2Place the appliance thermometer in a glass of water.

3Set the glass of water with the thermometer in the refrigerator on the middle shelf.

4Check the temperature on the appliance thermometer after 24 hours.
The temperature should register between 37 and 40 degrees Fahrenheit (2 and 4 degrees Celsius) in order to store food safely.
Only barely above freezing -- say 34 degrees Fahrenheit (1 degree Celsius) is even better for food storage at the cost of slightly higher electricity consumption. But check that food is not slowly freezing in any part of the refrigerator, which could make it less palatable.

5Look for the temperature control dial inside the refrigerator if you have to adjust the temperature, and make it warmer or cooler.
If you can't easily see the control dial, check the owner's manual for a diagram that shows the location.
When looking at the refrigerator temperature dial, you may see numbers rather than degrees. The majority of refrigerators use a set of numbers, with the lower numbers representing cooler temperatures and the higher numbers representing warmer temperatures.

6Move the temperature dial in the necessary direction to adjust the temperature up or down. Be sure to move the dial only one number in either direction because it probably will not take much to change the temperature in the refrigerator.

7Adjust the temperature balance control if your refrigerator has such a dial or sliding switch. This allows you to direct more or less cold air to the refrigerator section from the freezer section.

8Wait at least 24 hours, and then check the refrigerator temperature again.


9Observe the amount of frost in the freezer section of the refrigerator if you are unable to properly set the temperature.

10Defrost the freezer if the amount of frost is more than .25 inches (.64 cm) thick.

11Repeat the steps as necessary until the temperature is within the safe range.

12Use a permanent marker to draw a line on the dial after you locate the best setting on the refrigerator temperature dial. This will give you a reference point in case your dial moves and needs to be adjusted in the future.

Hope that helps in solving the problem...

How to set fridge temp


    1. The first thing you must know is that your refrigerator should be set at 37-38 degrees. Anything at 40 or higher and you are risking food born illness (food poisoning) or spoiling your food. Place your magnetic thermometer in the refrigerator.

    2. Set your dial on your refrigerator to the second lowest setting. (If your refrigerator is already equipped with a digital thermostat, simply set it for 37 or 38 degrees and do not move on to the next step)

    3. After 2 hours, check your thermometer reading. If your reading is 38 degrees, there is no need to go higher and you are ready to put your groceries in. Be sure not to open and close your refrigerator during these two hours or your temperature reading will be incorrect.

    4. If your reading is higher than 38 degrees, move your dial up to the next coldest setting and repeat the steps every two hours until you reach the correct temperature for your refrigerator.

    5. Once you have reached the correct refrigeration temperature for your refrigerator, place the magnetic thermometer in the refrigerator permanently and watch for changes.

    Typically, your refrigerator temperature will need to be adjusted with the seasons, a higher setting in the summer and a lower setting in the winter.

How to set a temperture


Hello,

By keep your refrigerator or freezer too cold, it unnecessarily wastes electricity. The recommended temperature is 37 to 40 degrees for the fresh food compartment of the refrigerator. The recommended temperature for the freezer compartment is 5 degrees. If you have a separate freezer for long-term food storage, it should kept at 0 to -5 degrees.

The following steps below is how to set the temperature of your refrigerator.

The first thing you must know is that your refrigerator should be set at 37-38 degrees. Anything at 40 or higher and you are risking food born illness (food poisoning) or spoiling your food.

Step 2
Place your magnetic thermometer in the refrigerator.

Step 3
Set your dial on your refrigerator to the second lowest setting. (If your refrigerator is already equipped with a digital thermostat, simply set it for 37 or 38 degrees and do not move on to the next step)

Step 4
After 2 hours, check your thermometer reading. If your reading is 38 degrees, there is no need to go higher and you are ready to put your groceries in. Be sure not to open and close your refrigerator during these two hours or your temperature reading will be incorrect.

If your reading is higher than 38 degrees, move your dial up to the next coldest setting and repeat the steps every two hours until you reach the correct temperature for your refrigerator.

Step 5
Once you have reached the correct refrigeration temperature for your refrigerator, place the magnetic thermometer in the refrigerator permanently and watch for changes.

Typically, your refrigerator temperature will need to be adjusted with the seasons, a higher setting in the summer and a lower setting in the winter.

Hope this helpout and take care.

I am having LG GR-B352 YC , what is the best temperature that i can keep initially and future??


Generic instructions to set temperatures in fridges:

Many manufacturers design these appliances to operate at 0 degrees F in the freezer and 34 to 36 degrees F in the fresh food compartment.

To set the temperature correctly, fill a glass with water (8 to 12 ounces) and place a thermometer capable of indicating 32 degrees and up into the glass with water (if the temperature goes below 32 degrees, the water will freeze - so no need to find a thermometer that indicates any lower). Place the glass with the thermometer in it on a shelf and wait. Putting the thermometer in a glass of water helps preserve the temperature reading while the door is open. You can skip the water and glass if you want - but you'll need to read the temperature as soon as you open the door.

The freezer will require a thermometer capable of displaying 0 degrees F. Place it on a shelf where it can be seen readily - but preferably in the rear - between items (to prevent the warm air from driving the indicator up when opening the door to read it).

It will probably be easier to set the freezer temperature first. Adjust both the freezer and fresh food thermostats to mid-points (if the fridge is empty - otherwise skip this step). Adjust the freezer thermostat up or down as needed to reach the desired 0 degree F temperature.

Once the freezer adjustments are complete, adjust the fresh food compartment thermostat as needed up or down to reach the desired temperature for it.

If you fridge is fully stocked, it may take some time for the temperature to stabilize and warm / cool the fridge's contents completely. This is further affected by how often the door(s) are opened and for how long. 24 hours is often claimed - but you might be able to sneak an 8 - 12 hour soak before reading the thermometers.

After the temperatures are set, you may find that the lower part of the fresh food area is partially freezing - simply adjust the thermometer up *slightly* as needed.

Please rate this reply if it was helpful - good luck!
