On most fridge dials, the higher number is colder. GE says 9 is the coldest setting on its 1 to 9 knobs, and Danby says 7 is the coldest on its 1 to 7 mini fridges. But the numbers are not degrees, and Whirlpool warns that you should confirm the direction in your own manual. Start in the middle, change one step at a time, wait a day, and let a thermometer tell you if you’ve hit 40°F or below.
The dial guesses, a thermometer knows. Two I’d look at (why these): TempPro TP110-2 (2-pack) Taylor 5924 dial (Amazon; as an Amazon Associate I earn from qualifying purchases)
Why Your Dial Has Numbers, Not Degrees
A dial with numbers doesn’t measure anything. It tells the fridge how hard to work: a higher setting usually means “cool more”. The temperature you actually get depends on the room, how full the fridge is and how often the door opens. Danby says exactly that in its compact fridge manual. So “5” in a warm kitchen in July can be a different temperature from “5” in a cool basement in January.
That’s also why two fridges set to the same number can feel completely different. The number is a starting point. The thermometer is the answer.
Dial Decoder: Which Setting Is Coldest?
Knob 1 to 9
Example: GE refrigerators. 1 is the warmest. GE recommends 5 for most kitchens.
Mini fridge 1 to 7
Example: Danby compact fridges. 1 is the warmest, 4 is recommended, and 0 turns the cooling off.
MIN / MED / MAX
Example: GE compact fridges. Start at MED and adjust from there.
Digital display
GE recommends 37°F for the fridge and 0°F for the freezer; Whirlpool uses the same factory defaults.
Your dial looks different, or has snowflakes instead of numbers? Check the label next to the dial or your manual. Whirlpool’s help pages say that on many models a lower number is warmer, but that you should confirm it in your owner’s manual.
How to Make Your Fridge Colder (or Warmer), Step by Step
- Find the control. The USDA says it’s usually in the fridge part of the appliance, even on fridge-freezers. On some mini fridges, like the Danby model cited below, the dial sits next to the interior light.
- Move it one step. One number, one snowflake, or one degree on a display. Whirlpool says to adjust one step at a time.
- Wait. Whirlpool’s help pages say to allow 8 hours for a freezer-control change and 24 hours (a full day) for the fridge; a full day is the safe choice. (My advice: don’t crank it to the coldest setting to “catch up”. Whirlpool warns that a fridge at 34°F or below can freeze food near the air outlets.)
- Measure. A thermometer in a glass of water in the middle of the fridge, read after 5 to 8 hours (USDA). You’re aiming for 38 to 40°F.
- Repeat if needed. Still above 40°F? One more step colder. Food freezing? One step warmer.
My tip: write the date and the setting on a sticky note inside the door every time you change it. After two changes, nobody in the house remembers what the dial was on before. The printable temperature log has a column for exactly that.
Fridge and Freezer With Two Controls?
Many fridge-freezers have one control for each section, and cold air moves between them. Whirlpool says a freezer set far below 0°F can push too much cold air into the fridge, and for food freezing in the fridge it recommends starting with the freezer control. GE’s recommended starting point for knob controls is 5 for both sections.
If you change both at once, you won’t know which one fixed it. One control, one step, one day.
Mini Fridge Dials: Two Things to Know
- 0 can mean off. On Danby’s compact fridges, 0 turns the cooling off. If your mini fridge suddenly feels warm, check that nobody bumped the knob to 0.
- The room, the load and the door matter. Danby says the temperature inside its compact fridge depends on the room temperature, how much is stored in it and how often the door is opened. So a mini fridge in a hot dorm room may need a colder setting than the manual’s starting point. (Garage? Danby says its compact fridges are not designed for places that aren’t temperature controlled, such as garages.) GE says its compact fridges typically run between 35 and 42°F, so check that yours is really at 40°F or below before you keep milk or leftovers in it.
What If the Dial Is Already on the Coldest Setting?
If the dial is on the highest setting and your thermometer still shows above 40°F after a day, the dial isn’t the problem. Things worth checking first, from the USDA and Whirlpool: is the door closing tightly, is the fridge packed so full that air can’t move, are vents blocked by food, are the condenser coils dusty? If none of that helps, a temperature control or sensor may be faulty, and that’s a job for the manufacturer’s service or a technician. Meanwhile, keep perishable food somewhere that is 40°F or below.
The opposite problem, food freezing even on a middle setting, has its own list: why your fridge is freezing food. And for what the target temperature is and why, see what temperature your fridge should be.
Fridge Dial FAQ
Is 1 or 5 colder on a fridge?
On most dials 5 is colder than 1, because a higher number means more cooling. GE says 9 is the coldest on its 1 to 9 knobs and Danby says 7 is the coldest on its 1 to 7 mini fridges. Whirlpool says to confirm the direction in your owner’s manual, so check the label on your dial.
What number should my fridge be on?
Start in the middle: GE recommends 5 on a 1 to 9 knob, Danby recommends 4 on a 1 to 7 mini fridge. Then use a thermometer and adjust until the fridge reads 40°F or below.
What is the coldest setting on a mini fridge?
Usually the highest number. On Danby’s 1 to 7 compact fridges, 7 is the coldest and 0 turns the cooling off. On GE compact fridges with MIN, MED and MAX, MAX is the coldest.
How long does it take for a fridge to change temperature after I turn the dial?
Give it time: Whirlpool’s help pages say 8 hours for a freezer-control change and 24 hours for the fridge, and the USDA says to check with a thermometer after 5 to 8 hours. A full day is the safe choice.
What temperature is a fridge on setting 5?
There’s no fixed answer, because dial numbers aren’t degrees. The real temperature depends on the model, the room and how full the fridge is. Measure it with a fridge thermometer.
