A refrigerator that has stopped cooling properly is the call we treat as urgent, because food safety is on the clock. Before you book anything, there are a handful of checks that take a few minutes and sometimes solve the problem outright.
1. The condenser coils
On most refrigerators these sit behind a grille at the bottom front or on the back of the unit. A thick coat of dust and pet hair insulates them and makes the compressor work harder for less cooling. A vacuum with a brush attachment, done every six months or so, is the single most useful piece of refrigerator maintenance most people skip.
2. The door seals
Close the door on a piece of paper and pull it out. If it slides out with no resistance anywhere around the door, the gasket is not sealing properly and warm air is getting in continuously. A worn gasket is an inexpensive part and a straightforward fix.
3. The temperature setting
It sounds obvious, but a setting bumped during cleaning, or a “vacation” or “showroom” mode left on by accident, causes more service calls than you would expect.
4. Overpacking
Air needs to circulate around stored food for a refrigerator to cool evenly. A shelf packed tight against the back wall vent can block airflow to the rest of the unit.
5. The room around it
A refrigerator in a garage, a mudroom, or against an exterior wall in a Chicago winter can be pushed outside its rated operating range in both directions – too cold in January, too warm in a July heat wave. If yours lives somewhere other than a normal interior kitchen wall, that is worth mentioning when you call.
When to stop checking and call
If the coils are clean, the door seals fine, and it is still not cooling – especially if you hear the compressor running constantly or not at all – that is a sealed-system or control issue, and it is time to call. The sooner we see it, the more likely everything in it is still salvageable.
