Quick answer: this free printable log records each refrigerator or freezer temperature twice a day, at opening and closing, for a full month on one page. Refrigerators must keep food at 41°F or below, and freezers must keep food frozen, with 0°F or below the usual target. Print one sheet per unit and tape it to the door.
A refrigerator temperature log is the simplest food safety record a kitchen can keep, and the one an inspector is most likely to ask about. This one covers a full month on a single page: one row per day, a reading when you open and another when you close, with room for initials and the fix if a unit runs warm. Print one sheet per cooler, freezer, or reach-in, tape it to the door, and file it at the end of the month.
Refrigerator and Freezer Temperature Log
| Date | Opening time | Temp °F | Initials | Closing time | Temp °F | Initials | If out of range: what you did |
|---|---|---|---|---|---|---|---|
Refrigerator: food must stay at 41°F or below. Read the thermometer in the warmest part of the unit, usually near the door. Freezer: food must stay frozen; 0°F or below is the usual target.
If a refrigerator reads above 41°F: probe the food and call for service. Chill and keep TCS food you know has been above 41°F for less than 2 hours. Discard it if it has been longer, or if you don't know how long.
Preview. The PDF has 31 rows, one for each day of the month, on a single portrait page.
How to Fill It In
- One sheet per unit. Write the unit and where it is ("walk-in cooler," "reach-in under the grill," "chest freezer, back room") and the month. Circle refrigerator or freezer.
- Read it twice a day. Once when you open and once before you close, at roughly the same times each day. A reading taken right after a delivery or a long door-open will run high, so wait a few minutes.
- Write the number you see, not "OK" or a checkmark. A column of 38s, 39s, and 40s shows a trend; a column of checkmarks shows nothing.
- Initial every entry. The point of the log is that someone looked.
- Fill in the last column whenever a reading is out of range, even if the fix was just closing a door left ajar. That column is your proof that problems get handled.
- Review it weekly. The manager or person in charge should glance at the sheet once a week and initial the bottom. FDA's guide for operators lists exactly this kind of review as a verification step.
The Rules Behind the Numbers
The FDA Food Code, which most states adopt as their food law, sets the targets this log checks:
- Cold holding: 41°F (5°C) or below for time/temperature control for safety (TCS) foods such as meat, dairy, cooked rice, cut melons, and cut leafy greens (§3-501.16).
- Frozen food must stay frozen (§3-501.11). The Food Code doesn't give a freezer number; 0°F (-18°C) is the target FDA gives consumers and the setting most commercial freezers are built for.
- Raw shell eggs go in a unit with an air temperature of 45°F or below (§3-501.16(B)), so a 41°F cooler covers them too.
- Every cooler holding TCS food needs a thermometer that measures the air in the warmest part of the unit and is easy to read (§4-204.112). An air thermometer has to be accurate to within 3°F (§4-203.12).
Here's the honest part: the Food Code makes the person in charge responsible for monitoring holding temperatures (§2-103.11), but it generally doesn't require a written log. FDA's own inspection guidance notes that, with a few exceptions, formal records aren't required at retail. Some states, counties, and HACCP plans do require them, and the 2026 Food Code moves toward written monitoring records. Either way, a log is the easiest way to show an inspector that monitoring happens.
What to Do When a Unit Reads Warm
The air reading is a warning light; the food temperature is what matters. When a refrigerator reads above 41°F:
- Check the food, not just the air. Push a probe thermometer into a few items in different parts of the unit, especially near the door and the top shelf.
- Look for the easy cause. A door propped open, a blocked fan, a hot pan put in to cool, an overloaded shelf, or a frozen-over coil.
- Move food that is above 41°F to a working unit, or chill it in an ice bath, and note the time.
- Decide what to keep. The Food Code doesn't set a time limit for food found too warm. FDA's guide for operators says the choice depends on how long food has been out of temperature, which is why frequent checks matter: they can mean the difference between chilling food and throwing it out. A common, conservative rule: chill and keep TCS food you know has been above 41°F for less than 2 hours, and discard it if it has been longer or nobody knows how long. If your health department has its own rule, follow it.
- Call for service if the unit doesn't recover, and write down what you did in the last column.
A freezer reading above 0°F isn't a violation by itself, but thawing food is. Probe anything that has gone soft: food still at 41°F or below can move to a refrigerator and be used like any refrigerated food, and anything warmer gets the same keep-or-discard decision as above.

Most commercial units have a built-in display, but built-in sensors drift and often sit in the coldest spot rather than the warmest. A cheap dial thermometer hung near the door is the reading most kitchens actually log. Our refrigerator thermometer guide compares dial, min/max, alarm, and WiFi models.
A 3-inch dial that reads from -20°F to 80°F, with colored zones for refrigerator and freezer ranges. It hangs from a shelf or stands on its own. Pros: no batteries, NSF listed, cheap enough for every unit. Cons: it shows the temperature right now, not what happened overnight. Best for: the everyday reading you write on this log.
A digital display that remembers the highest and lowest readings since you last cleared it. Pros: catches a cooler that warmed up overnight or during a long delivery, which a once-a-shift reading can miss. Cons: needs batteries, and it isn't NSF listed, so pair it with an approved thermometer if your inspector cares. Best for: the walk-in and any unit you don't fully trust.
Check every thermometer against ice water now and then, and record it on the thermometer calibration log. For a full rundown of probe thermometers, see our best food thermometers guide.

Frequently Asked Questions
How often should restaurants check refrigerator temperatures?
The Food Code doesn't set a number; it requires the person in charge to monitor holding temperatures. Twice a day, at opening and closing, is the common minimum. Busy walk-ins and units that have given trouble are often checked every few hours.
What temperature should a restaurant refrigerator be?
Cold to keep TCS food at 41°F or below. Many kitchens set units at 36°F to 38°F so that a busy shift or a delivery doesn't push food over the limit.
What temperature should a restaurant freezer be?
The Food Code only says frozen food must stay frozen. 0°F or below is the standard target, and it's the number FDA gives for safe freezer storage.
Are refrigerator temperature logs required by law?
Not under the FDA Food Code in most cases, though monitoring is. Some states, counties, and HACCP plans require written logs, so ask your health department. A log is still the easiest way to prove monitoring happens.
How long should I keep completed logs?
The Food Code doesn't set a period for these logs. Keep them at least as long as your health department asks; many operators keep a year so that past inspections and any illness complaint can be checked against them.
Bottom Line
Print a sheet for each unit, read it twice a day, write down the number, and act when it's above 41°F. The other five logs in the free log set cover holding, cooling, receiving, sanitizer, and thermometer checks.
