Setting the Right Temperature: 40 Degrees for the Fridge, 0 for the Freezer
Last verified: September 2026
Everything you need to get your fridge and freezer to the right temperature — the two numbers that matter, why the dial isn't degrees, and how a thermometer settles the question. Rather have a hand? My number is (330) 200-8042.
Setting Your Fridge and Freezer Right, at a Glance
Two numbers do almost all the work here: keep your refrigerator at 40 degrees or below and your freezer at 0 degrees or below. The tricky part is that most dials aren't marked in degrees at all, so the only way to know you're really there is a thermometer. This guide covers the two numbers, why the dial can't be trusted on its own, and how to dial in and verify both appliances, for town and rural homes alike. There's a printable 29-page version up top.
Common Questions
1 What temperature should my refrigerator be set to?
Set your refrigerator to 40 degrees Fahrenheit or below. Most dials aren't marked in real degrees, so check the actual number with an appliance thermometer.
2 What temperature should my freezer be set to?
Set your freezer to 0 degrees Fahrenheit or below. That keeps food solidly and safely frozen for the long term.
3 Why doesn't my fridge dial show degrees?
Many fridges use a simple 1-5 or low-to-high dial instead of real degrees. The only way to know your actual temperature is to check it with a thermometer.
4 Is it bad if my fridge is colder than 40 degrees?
Colder isn't automatically better. A fridge set too cold can freeze lettuce, eggs, and milk. Aim for just under 40 degrees, not the coldest setting available.
5 How long should I wait after changing the temperature setting?
Give it about 24 hours to settle before checking again. Adjust a notch at a time and recheck, rather than making one big change all at once.
6 Do I really need a thermometer if the fridge feels cold?
Yes. 'Feels cold' isn't the same as 40 degrees or below, and you can't tell the difference by touch. An appliance thermometer is the only way to know for sure.
Would You Rather I Just Help?
Getting the fridge and freezer set right is one of the simplest, most useful visits I do — and once it's dialed in, it usually stays that way. I'll put thermometers in place, get both appliances reading right, and answer whatever else is on your mind, with nothing to sell you. $99 flat for a visit, 30-day come-back-free.
Would you rather I just do this for you?
No shame in it — plenty of folks would rather hand it off, and that's what I'm here for. I'll come to your home, set it up right, and make sure it's working before I leave. Flat $99 per visit — no jargon, no upsell, and every visit is 30-day come-back-free.
Not a hardware job? I can often fix it remotely for $49 — a secure screen-share, up to 2 hours, that you watch the whole time and can end whenever (included free for $39/mo Support Plan members, and it counts toward the $99 if it turns out I need to come out).
