A refrigerator that is starting to fail does not usually stop cooling all at once. It drifts. The food tastes a little off, the milk turns sooner than it used to, and the freezer starts to frost in a way it did not before. By the time the fridge is obviously broken, the food has often been paying the price for weeks.

The early signs
Watch for a motor that runs longer than it used to, or for a hum that changes pitch. Notice ice building up in the freezer or water pooling at the bottom of the fridge. Check whether the door seal is cracked, torn, or no longer grips the cabinet all the way around. Look for milk or other dairy that sours before its date, leftovers that smell off sooner than expected, and produce that wilts in a drawer that used to keep it fresh. Each sign is small. Several together mean a repair visit is worth scheduling.
Check the basics yourself
Place an appliance thermometer on a shelf in the middle of the fridge and check it on a few different days, ideally at the same time of day. A reading that climbs and holds warm is the signal to act. Test the door seal by closing it on a sheet of paper and pulling it out. If it slides out with no resistance, the seal is not holding. Look at the coils at the back or underneath the fridge, and clear away dust and debris so air can move around them.
What goes wrong, and how to limit it
The main risk is food that has been warm for too long. Dairy, cooked leftovers, and cut produce are the usual problems. If you cannot tell how long a food has been out of the cold, the public food safety guidance listed on our Sources page explains the usual rules for throwing food away. Keep the fridge stocked just enough that cold air can circulate, and do not pack it so tightly that the vents are blocked.
Who sees it first
From far away, you will not see the thermometer. Ask a neighbor or a local visitor to open the fridge during a check and read the number aloud, or ask your parent to read it to you on a video call. Give them a simple script: read the number, say whether the door closes firmly, and report any frost or water. Ask them to do the check on the same day each week so the readings can be compared.
When to call for a repair
Ask the repair company to write down what is failing, what the fix involves, and whether the unit is likely to need replacement soon. Ask whether the problem is a part or the whole system, and ask how long the repair is expected to last. A written diagnosis lets you compare options calmly rather than deciding in a hurry.
What to do tonight
Place a thermometer in the middle shelf of the fridge and check the reading tomorrow morning. Look at the door seal while you are in the kitchen and note whether the paper test holds.
What to leave with the doctor
If your parent has been skipping meals or has been eating less because food has spoiled, tell the doctor. Bring a short note of what got thrown away and roughly how often it happened. Ask whether the appetite or grocery pattern should be looked at as part of the next visit.
