Your mother says the refrigerator is working. She can hear it hum. The light comes on when she opens the door. The milk feels cool.

None of those checks tells you whether the food has stayed cold enough. A refrigerator can run without reaching the right temperature. It can cool unevenly, cycle on and off, or recover after warming long enough to make the history unclear.
The early warning is not always a puddle on the floor. It may be soft ice cream, sweating packages, milk that spoils sooner than expected, or a refrigerator dial that keeps getting turned colder. From far away, you need a number, a time, and someone who can see what the appliance is doing.
Start with the thermometer, not the control dial
Ask whether there is an appliance thermometer inside the refrigerator. The numbered control built into many refrigerators is a setting, not a temperature reading.
The U.S. Food and Drug Administration says a refrigerator should stay at 40°F or below and a freezer at 0°F or below. The U.S. Department of Agriculture also recommends keeping an appliance thermometer in each compartment. These agencies, along with other public sources used by this desk, are listed on the Sources page.
If there is no thermometer, ask someone local to bring one. Put it near the middle of the refrigerator, away from the door, cooling vent, and walls. A reading taken from the door can make a warm refrigerator look better or worse than the compartment where most food sits.
Have the person photograph the thermometer in place. Ask for another photograph after the door has remained closed for several hours. One reading immediately after groceries were loaded or the door stood open does not tell you the refrigerator’s usual temperature.
Recognize the pattern before calling for repair
A single warm reading tells you to protect the food. A small record helps you understand what failed. Ask the person in the house to check these points without taking the appliance apart:
Is the freezer still holding food solid? Is the refrigerator warm everywhere, or mainly near the door? Does the interior light work? Can the motor or fan be heard? Is the door closing without being pushed? Is a package, drawer, or shelf keeping it ajar? Is frost covering an inside wall? Are containers packed tightly against the vents? Is the plug seated firmly? Did another appliance or clock lose power?
Photograph the temperature, control setting, inside vents, door seal, plug, and model label. Do not have your mother pull the refrigerator away from the wall if that would be awkward or unsafe. The model label and visible conditions are enough for the first service call.
These details separate several problems that sound the same over the phone. A brief power interruption is different from a door that never sealed. A freezer that remains cold while the refrigerator warms is different from an appliance that has stopped cooling altogether. A crowded vent may be visible before anyone assumes the machine has failed.
Do not use smell or taste as the test
Ask when someone last knows the refrigerator was at 40°F or below. If nobody knows, say that plainly. Do not turn an uncertain history into a confident estimate.
The USDA says not to taste food to decide whether it is safe. It also says refrigerated perishable food should be discarded if it has been above 40°F for more than two hours. During a power outage, an unopened refrigerator generally keeps food cold for about four hours. Those are different clocks: one measures the outage, and the other measures how long the food itself was too warm.
Make a short inventory before anything is discarded. Separate meat, poultry, fish, eggs, milk, soft cheese, opened foods, cooked dishes, and leftovers from shelf-stable items. Record the thermometer reading and what is being removed. Do not ask your mother to judge each container by smell, appearance, or memory.
If the temperature history is uncertain, use the USDA and FDA guidance for the specific food rather than improvising a rule. A repair technician can assess the appliance. That person is not the one to decide whether warmed food should be eaten.
Make the service call usable from another state
Before booking a visit, have the model number, address, temperature readings, photographs, and a short description ready. Say what still works and what does not. For example: the light works, the freezer food is soft, and the refrigerator thermometer reads above 40°F after the door stayed closed.
Ask the service company to confirm the arrival window with both you and the person opening the door. Ask whether the technician needs clear space around the appliance, access to the electrical panel, or permission to move it. Decide who may approve work and who receives the written findings.
Request a note that states what was checked, what failed, what was changed, and the temperature observed before the technician left. “Running now” is not a complete handoff. Arrange for someone to photograph the thermometer again after the refrigerator has had time to settle.
If you do not have a reliable person who can take the photographs, remove food, and meet the technician, this is a reasonable job for local help in St. Louis. The task is not simply standing in the kitchen. It is closing the gap between the first warm reading and proof that the refrigerator is holding temperature again.
Build an early warning that does not depend on Mom noticing
Leave an appliance thermometer where it can be read without moving food. Put a simple instruction nearby: photograph the reading, the control setting, and the closed door. If someone visits regularly, add the temperature to the visit checklist.
Keep the model and serial numbers, service company, last repair note, and photographs in your household folder. Add the name of the person who can remove questionable food and receive a grocery delivery. The plan should still work if your mother cannot explain what happened.
If warm readings repeat, compare the circumstances. Note whether they follow grocery delivery, heavy loading, a door left ajar, a power interruption, or no obvious event. Repeated readings are more useful than repeated reassurances.
What to do tonight
Ask for one photograph of an appliance thermometer in the middle of the refrigerator and one of the freezer thermometer. If no thermometers are present, arrange for a local person to bring them. Tell your mother not to taste questionable food. Identify who can go to the house if the reading is above 40°F, document what is inside, and follow public food-safety guidance for anything that may have warmed.
Start one note with the reading, the time it was taken, when the refrigerator was last known to be cold, whether the freezer food is solid, and whether there was a power interruption. Keep that note with the appliance photographs and service record.
What to leave with the doctor
You do not need to ask the doctor to diagnose the refrigerator problem. If your mother ate food that may have been held too warm and she later feels unwell, leave the clinician the useful sequence: what she ate, when she ate it, when symptoms began, what symptoms you or she observed, and whether she can keep fluids down. Include her medication list and existing health conditions. Ask what changes should prompt another call or more immediate help, and write down the answer so the local person has the same instructions.
