Refrigerator Repair

The order a warm compartment gets worked through

• A logged temperature in both compartments against the set point, over a full cycle rather than a single reading
• Condenser condition, and whether the installation gives it the air path it needs
• Door seals tested all the way round, and hinge alignment, because a leak here explains most of the rest
• The evaporator, looked at directly — frost pattern says more than any code
• The defrost circuit: heater, terminating sensor, and whether cycles are completing
• Evaporator fan behaviour, and the damper metering air into the fresh-food side
• Sensors, against an independent thermometer, before any board is suspected
• Only then the sealed system, and only with the readings to support it

The failures that account for most of it

Door seals, evaporator fan motors, defrost heaters and sensors, damper assemblies and ice maker components make up the great majority of refrigerator repairs on built-in equipment. They are all wearing parts, they are all replaceable in the kitchen on most designs, and none of them is a reason to think about a new appliance.

Control boards are less common than the internet suggests. A board is genuinely at fault often enough to matter, and it is also the easiest thing to blame when a sensor is lying to it, so it is confirmed rather than assumed.

When repair stops making sense

The line is the sealed system. A compressor failure or a refrigerant leak in a foamed-in evaporator on a cabinet that is well over a decade old is the one case where replacement deserves serious thought, and even then it depends on the cabinet: a built-in column integrated into custom joinery carries a replacement cost far beyond the appliance itself, because the cabinetry rarely accepts a different unit without work. Everything above the sealed system is straightforwardly worth fixing.
