Verdict: False. USDA advises keeping eggs in their carton in the coldest part of the refrigerator, not in the door, and Whirlpool says the door is the part of the fridge most prone to temperature swings, so it suggests the lower shelves for milk.
Where the idea comes from
The refrigerator itself seems to answer the question. Many models come with an egg tray in the door and tall door bins sized for milk jugs, so it's reasonable to think that's where those foods belong. The door is also convenient: milk for coffee and eggs for breakfast are within reach without moving anything.
What the evidence says
USDA's Food Safety and Inspection Service, in its fact sheet Shell Eggs from Farm to Table, says to store eggs in a refrigerator set at 40°F or below, and to "keep them in their carton and place them in the coldest part of the refrigerator, not in the door."
Whirlpool's guide to organizing a refrigerator explains why: "The door is the part of the fridge that is most susceptible to fluctuations in temperatures." It recommends milk on the bottom shelf, toward the back, and eggs on a middle shelf, where temperatures are steady. It describes the lower shelves as typically the coldest part of the fridge and suggests using the door for condiments and other less perishable items such as nut butters, pasteurized juices, ketchup, mustard, pickles and olives.
Every time the door opens, the bins on it swing out into room air. In a busy kitchen that happens many times a day.
What to do instead
- Keep eggs in their original carton on an inside shelf.
- Put milk on a lower shelf toward the back.
- Move condiments, dressings, sauces and pasteurized juices into the door bins.
- Use an appliance thermometer to confirm the main compartment holds 40°F or below. Our post on what the numbers on a fridge dial mean explains how to set it.
- Keep door openings short, especially on hot days.
Exceptions worth knowing
- •The egg tray isn't dangerous to own. It's a matter of where food stays most consistently cold. Use it for small condiment jars if you like.
- •Small fridges in apartments and ADUs have less shelf space, so prioritize shelf space for eggs, milk, meat and leftovers.
- •Hot weather increases the swing. A door opened often in an un-air-conditioned kitchen during an LA heat wave is warmer than usual.
- •A door that doesn't seal makes the whole fridge warmer. Close the door on a strip of paper; if it slides out easily, the gasket may need attention.

The short version: Eggs and milk go on inside shelves; the door is for condiments.
A main compartment that won't stay at 40°F, even with food stored the right way, is worth a refrigerator repair visit. TrueFix Los Angeles is at (213) 787-3989.
