Start with what you own
Refrigerator types
The word refrigerator covers eight quite different appliances. A built-in is serviced from the front without leaving its opening; a column is two appliances that fail independently; an undercounter unit breathes through one grille and nothing else; a chest freezer in a cold garage may be behaving exactly as designed. Knowing which one you have answers half the question before anybody arrives.
Built-in refrigerator
Flush with the cabinets, serviced from the front, and almost always repaired rather than replaced.
Refrigerator column
Separate refrigerator and freezer towers, each with its own sealed system — so a fault stays on one side.
French door refrigerator
Two fresh-food doors over a freezer drawer — the most common premium layout, and the one with the most to go wrong at the door line.
Side-by-side refrigerator
Full-height freezer beside full-height fresh food, with the ice maker and dispenser built into the freezer door.
Undercounter refrigerator
A single 15 to 24 inch unit under the worktop — front-vented, tightly enclosed, and easily starved of air.
Not sure which you have?Start from what it is doing
If the cabinet in your kitchen does not obviously match one of these, work from the symptom instead. It reaches the same answer from the other end.
18 problemsIn order of costWhat to check first Go to the problemsWhat a repair
usually costs.
A useful rule: weigh the repair against what the appliance would cost to replace in the same opening. On a freestanding unit that is a straightforward comparison. On a built-in or a column it is not, because the replacement has to match the cabinetry, and that is why sealed-system work on those types is still normally worth doing.
| Repair | Relative cost | Notes |
|---|---|---|
| Door gasket or alignment | lowest | Often the cheapest job on the list, and frequently the real cause of a much more expensive-sounding symptom. |
| Defrost heater, thermostat or sensor | low | The usual answer when frost has built up and the fresh-food side has drifted warm. |
| Evaporator or condenser fan | low | Common, quick, and the reason a freezer can be cold while the refrigerator is not. |
| Water inlet valve or line | low | Covers most no-water and no-ice calls once the filter and the shut-off have been ruled out. |
| Defrost drain clearing | low | The sheet of ice under the bottom drawer, before it becomes water on the kitchen floor. |
| Ice maker assembly | moderate | Replaced as a module rather than rebuilt on nearly every current design. |
| Control board | moderate | Priced against the model, and on built-in units the part is the majority of the cost. |
| Compressor or sealed system | highest | The one repair where the decision is genuinely open, and where the type of appliance decides it. |
| Maintenance visit | lowest | Not a repair. The visit that prevents the largest share of the ones above it. |
Not a refrigerator? Each of these is its own appliance, and has a site of its own.
