Refrigerator Temperature Control Dial – What Do The Numbers Relate To? – Cold, Colder, Coldest

Question: Our older refrigerator seems to be much colder than normal. The dial on the refrigerator setting dial has the numbers 0-9. The problem is that there is no indication of which number (higher or lower) to set the dial to make the refrigerator colder or warmer.

Generally, what number is coldest on a refrigerator? The highest number or the lowest number? Quick Answer: The higher number is the coldest setting.

refrigerator temp control setting numbers

Most refrigerator temperature settings are controlled with a dial or slider. They are sometimes labeled 1 through 5 or 1 through 9. If you are not sure what to set it to, then set it somewhere in the middle. If the dial is numbered 1 to 5 set it on 3, if the dial is numbered 1 to 9, then set at 4.

USUALLY the higher the number on the temp control dial, the colder the temperature your refrigerator will get. If your drinks and food are not as cold as you like, set the temperature dial up one number higher. If it is at 3 and you want your food colder, set it to 4 and test 12-24 hours later to see if your food is at the temperature you desire.

fridge dial settingsMost older refrigerators will have a simple temperature dial control setting as seen above.

Most Kenmore, LG, Samsung, Maytag, GE, and newer Whirlpool refrigerators have an actual digital readout that displays the exact temperature. These newer refrigerators still have temperature control sliders, knobs, dials, and digital touch pad controls. This makes it much easier to know and control the exact temperature in your fridge or freezer.

best thermometer for inside refrigeratorA thermometer like the one above is perfect to keep in your fridge to know exact temp.

An easy way to check to find out the exact temperature is to use a simple inexpensive thermometer in the refrigerator. Most refrigerator controls do not show the actual temperature so using a thermometer is a good idea. Your refrigerator should be below 40 degrees F to be safe. The best temperature to suit just about any refrigerator is ideally at 37 degrees F.

If the settings on your temperature control dial seem to be making the fridge too cold or too warm, use the thermometer reading to adjust the settings dial until you have the best temperature. Allow 12 to 24 hours between each adjustment. Low (colder) temperatures are key to prevent bacteria growth and to keep your food fresher longer. Here is information on storing food at safe temperatures.

refrigerator temperature setting recommendation

If you turn the dial to number 0, that effectively turns the fridge off. Setting the dial to 9, the refrigerator will be working at its max capability. Your personal temperature setting will depend on how much food is kept in the refrigerator. If your fridge is packed with food, it needs to be on a higher number setting to maintain a low (colder) temperature.

The temperature controller dial or slider on your refrigerator is a thermostat. It kicks the compressor on when the refrigerator is not cold enough. The refrigerator then turns the compressor off when the desired temperature has been reached. The more food you have in your refrigerator, the more stable the temperature will be. Set the thermostat to the middle of its range and leave it for 12 to 24 hours.

    The temperature control on your Frigidaire top freezer refrigerator (model FRT21C5AQ7) is designed to adjust the temperature of the fridge compartment.
    The “LO” setting refers to a lower temperature setting, while “HIGH” refers to a higher temperature setting.
    The ideal temperature for your fridge compartment is between 35°F and 38°F (1.7°C and 3.3°C).
    If you want to store food for a longer period, you can set the temperature to the lower end of this range.
    If you want to cool beverages quickly or have a party and need extra space, you can set the temperature to the higher end of this range.
    It is important to note that the temperature control should be set correctly to ensure that your food stays fresh and safe to eat.
    If you notice that your fridge compartment is too warm or too cold, you may need to adjust the temperature control accordingly.

  2. 2003 Frigidaire top freezer refrigerator (model FRT21C5AQ7):

    On the very left on the bottom shelf, there’s a temperature control. It slides from “LO” to “HIGH.” Anyone know “lo” and “high” refer to?
    It’s like when someone says, “turn the AC up.” So they mean, turn it colder or turn the temperature up?
    Obviously, the engineers had no idea how vague the English language can be.
    Anyone know the answer? Yes, I’ve got a refrigerator thermometer, but it will take a while for it to measure/reflect temperature changes, and we’ve got a whole duck air-drying in the refrigerator (need the coldest temp setting).
    And yes, I should have tested this beforehand, but it doesn’t excuse the stupidity of the temperature setting labels.

    I have a Frigidaire side by side refrigerator maybe 5years old the freezer part is freezing perfect but the fridge part isn’t cold enough for me. The thermostat is on 7for the freezer and 7 for the fridge side. The controls go from 0-9 is nine the coldest. If so what should I do. I thing the warranty is long over.

  4. Jeanne Mahoney

    My Hotpoint refrigerator in a rental apartment has no numbers or letters on the control dial, just a grey swoosh, wider at one end. It’s impossible to tell which way to turn it to make it colder.

  5. ALLEN VETTER - DIY Repair Assistant

    Concerning you Maytag French door refrigerator and it’s touch pad for the temperature settings numbers 0-7….
    The highest number is the COLDEST setting, so in your case, it would be 7 for the coldest setting.

  6. Have a Maytag French door refrigerator and it’s a touch pad for the temperature settings. For the freezer the numbers are 0-7. What is the coldest setting.

  14. My refrigerator temperature control only have cold and colder (green n white colour) Which one should I use to get the actual temperature?

  15. I have a beko frost free (it’s supposed to be frost free) fridge freezer today I decided to have a go at cleaning drain pipe as I was getting ice frost buildup in back of fridge even tho I only have it set at say 3 there’s 1-6 and a min max as well so using bicarbonate of soda I put a teaspoon in drain hole and poured 2+mugs of hot water to flush pipe through u wouldn’t believe the amount of gunk that came out luckily I’d had the foresight to place the end of drain tube into a large bottle I’d also noticed that the drain pipe wasn’t even connected fitted drain hole in back of fridge so I fitted it as best as I could everything seems to function but I’m still getting frost ice in back of fridge door seals seem ok I’ve turned fridge down to min.

  16. Dials numbered 1 to 9. If the default is 5, by how how many degrees is the temp changed in the freezer and in the fridge by moving the dial by 1 number in the freezer and in the fridge? What is setting 1 equivalent to in degrees Fahrenheit in the freezer and in the fridge? Likewise setting 9 equivalency?

  17. I have a 20 year old Whirlpool refrigerator and have a problem with temperature setting. There is a sliding knob. At the top it says “cold” and at the bottom “cooler”. please let me know which way to turn the knob to lower the temperature. Thanks

  18. I have a Whirlpool Gold refrigerator-on-top, freezer-on-bottom. The ice cream in my freezer seems to hard, but I have it set on “1.” “Off” is right next to the “1” setting, so I figured this was the lowest/warmest setting. Just seems weird my ice cream is hard as a rock. FYI, the refrigerator above is set at “4.” I’ve owned this refrigerator since 2001, so 17 years. Has run fine.

  19. I have a 2000 KitchenAid refrigerator model number ktrs22mjxh00. Temp # on both fridge and freezer go 1-7. It was working fine until we had a hurricane and somebody put the refrigerator and the freezer on the lowest setting so they stay colder longer when the power went out and ever since then, I can’t seem to get it back right because I don’t remember how it was set to begin with. So I set it at #4 for both but now there is water dripping from roof in fridge area, coming from freezer and it pools into area below produce drawers. I frigured the freezer not cold enough, turned it up to 5 waited a couple days and its still doing it. Is this something other than temp control? Its a self defrost but should i turn it off so if there is some ice build up somewhere i cant see can thaw, and then set it. And what is the proper settung #’s? Thanks

  20. I’m just relieved that I’m not the only one who is baffled when I go to adjust the temp on every fridge I’ve ever owned or used!
    Initially I think I know exactly what the labels mean (my 1st instinct is correct).
    Are they saying turn it left for warmest or that the warmest temp is on the left hand side of the dial (which means you’d actually have to turn it right to get the warmest setting.)
    And I struggle between whether 1 is the coldest setting since it’s the lowest # or is 5 the lowest?
    I think manufacturers could have done a lot better job with clarity on the labeling (ridiculous to need a manual or Google every time I need to adjust the temp) and it seems like newer fridges have done that.
    In the meantime I think a Post-It note inside my fridge will come in handy till it is time for a newer model fridge.

  21. The higher the number the colder the fridge, therefore 9 would be the coldest setting and 0 the warmest.

  22. Linda Bingham

    I have a old side by side refrigerator from 2000.
    It has slider controls numbered from 0-9 what number is colder?

  23. If the controller is a thermostat, it should trigger when the temperature inside gets too warm. So why does it need to be changed for summer vs winter ? is it because the temperature is uneven in a fridge and so where the thermostat is, it needs to be colder in summer?

  24. DIY Project Help Tips

    Check to see if there is any blockage that is preventing the air from flowing as designed.
    It could be frozen and covered with ice.
    Try defrosting the fridge and go from there.

  25. I have a Whirlpool WRNA232 refrigerator.
    7 days ago we’ve changed the timer and bought the same brand one but after 2 days the top level got froze and fresh food compartment didn’t flow air.
    It’s very slow air movement in the fresh food compartment.
    I set both the temperature control to middle level but the problem continues.

  26. DIY Project Help Tips

    J. Brown,
    Try turning the knob up “higher” or to a larger number or more snowflakes to make the fridge colder.

  27. I have a new whirlpool side by side. model wrs325fda 0. I set the refrigerator on the center position two weeks ago. at first it seemed ok. now it gets too warm/ and my fridge is in the danger zone in the 40 degrees. If I turn it to colder 3/4 or more it will stay in the safe zone. This does not seem normal to me. I think it should be cold to the point of being safe at the medium setting. Am I wrong?

  28. I have a 4 month old Whirlpool refrigerator that has ‘snowflakes’ rather than numbers on the dial. It’s not cold enough but I have no idea which direction to turn the dial to make it colder. The manual is no help at all. It was factory set at 3 snowflakes but the temperature is routinely around 42 degrees or sometimes higher. Do I set the dial to 4 snowflakes or 2?

  29. samantha Ashton

    I have purchased a used Whirlpool chest freezer, no model number, it’s working but does freeze up.
    I’d like advice on what the signs mean = e2

  30. My fridge is currently on zero but it freezes everything on top. it has dial ranges from 0-7, please assist.

  31. Christian Oppong

    My Hitachi (110v) table top refrigerator (weighs about 25kg) has a separate chamber for freezer and fridge.
    But the freezer cannot solidify a 1.5 liter bottle of water alone in a period of 5 hours.

  32. My GE has no numbers on dial…where to set it..in the middle keeps fridge on 40…should I turn to right or left for colder? if colder ice builds up around fan in freezer.

  33. My Hotpoint fridge has no numbers, just a fan symbol. How to adjust it? It is too cold!

  34. My 1989 Kenmore freezer on top has: Freezer manual control of hinged door allowing control of how much cold air drops down from the freezer; with flashlight you can see door wide open 1 and closed down 4.
    Refrigerator thermostat control determines how long compressor runs where 0 = off and 4 = wide open coldest.

  35. DIY Project Help Tips

    Yasin Najib,
    If the freezer knob is stuck, you can try unplugging the refrigerator/freezer and removing the knob and temp control assembly to see if it needs to be replaced or can be repaired.
    It may just have gunk stuck in it and therefore will not turn or it may have failed and needs to be replaced.

  36. My wife’s Aritson-Hotpoint refrigerator’s freezer knob is stuck at “S” and it wont budge.
    It has graduations from 1 to 5 and then S.
    Could you please advise on how to go about this problem?

  37. DIY Project Help Tips

    Allan Calhoun,
    For side-by-side Whirlpool refrigerators, A is coldest, B is medium, and C is warmer usually.
    If you can give us the model number we can tell you for sure.

    Jeff Geiger,
    5 asterisks on your Maytag refrigerator should be the COLDEST SETTING.

  40. My Maytag refrigerator shows 1 asterisk up to 5 asterisks. Which is the colder setting?

  41. DIY Project Help Tips

    Peter Bird,
    Put a multimeter on it and check to be sure it is working properly. It may also have something to do with the wiring going from there to the main control. Troubleshoot to find the issue.

  42. There are only two wires so i don’t think i could have mis-wired it. It is a universal part. Any way to tell if cold control is faulty?

  43. DIY Project Help Tips

    The cold control on your Admiral refrigerator may be faulty or installed wrong if now it is ultra cold and it has no ability to control temp. Check the wiring. Is the part you replaced universal or OEM?

  44. Just replaced the cold control on our 1996 Admiral side by side frig. Originally not staying cold enough and things thawing out. Replaced cold control and now stays too cold and stuff freezing even in fridge area despite setting. Cold control will turn fridge off when I turn it to the off setting but seems to be no adjustment when trying to set coldness. Compressor will shut off so I don’t think its a run on compressor.
    Any suggestions?

  45. Berniece Schafer

    I have a 19 year old Fisher & Paykel. The temperature control is dual. It has 0 to 7 plus two thermometers. One is with the mercury right to the top is at the 0 end, and the other is with the mercury right at the bottom is at the 7 end..
    So, Is the mercury right to the top indicating that is the coldest or the warmest. Very ambiguous.

  46. DIY Project Help Tips

    After replacing any part in your fridge, you may need to give it a little extra time to get to temp… Either way if you put the temp setting at 3, it should level out and be okay. Keeping the temp setting at 5 does make the compressor work more but should not be a factor. Keep the temp setting at the number you need to keep your food at the “right” temp. Try going back to temp setting 3 and make sure the fridge gets and STAYS at the temp you desire.

  47. I just replace a fan in my freezer. I set my temp setting to 3 (5 coldest) , the temperature in the frig reached 40 degree F. Then I set the temp setting to 5 coldest, the temperature in the frig dropped to 38 degree F (which is OK).

    My question:

    1. if I turn back the temp to 3, does the temp still keep the temperature 38 degree F?
    2. Keeping at 5, does it damage the compressor fast.

  48. DIY Project Help Tips

    It may be possible your fridge temp setting of 0 is coldest and 9 is the opposite. That is unlikely but may be possible. What make and model fridge is it? How old is the fridge? If you are in an apartment, you should be able to call maintenance and have them look at it. The temp dial may be malfunctioning and the complete temp assembly may need replaced.

  49. I’ve just moved into a new apartment and even with the temp setting on 0, effectively off my food etc is still freezing. Any ideas what the problem could be and/or how to fix this?

  50. DIY Project Help Tips

    Norma Guiterrez,
    No, changing the temp on your fridge often will not damage your refrigerator. Just allow 24 hours each time you adjust the refrigerator temp controls for the temperature to stabilize.

  51. Norma Gutierrez

    Does changing the refrigerator temperature settings too often cause damage the refrigerator?
