By manufacturer
The brands in these kitchens
Two built-in refrigerators can share a compressor supplier and still need completely different diagnoses, because what separates these platforms is not the cooling — it is the control architecture, the sensors, and how much the appliance will tell you before you put a meter on it.
What the badge changes
Three things, and cooling is not one of them
The first is what the appliance remembers. Some platforms store a fault history you can read at the panel, which turns an intermittent complaint into a list with times against it. Others tell you nothing and every reading has to be taken by hand.
The second is how the sensing is done. A thermistor read in ohms, a thermocouple, a mechanical thermostat and a networked sensor module all fail in ways that look identical from the kitchen and are diagnosed nothing alike.
The third is the parts channel. On some of these makes every component is still catalogued and arrives in days. On others, a board for a fifteen-year-old built-in is whatever is left in the country — and that single fact decides more repair-or-replace conversations than the price of the part ever does.
How they turn up
These names travel in pairs
The kitchens around here are rarely single-badge. A Sub-Zero column beside a Wolf range is the standard pairing in a rebuilt Brookline Victorian. Thermador and Miele arrive as a full suite. Viking tends to be a house that was renovated in one go, twenty-odd years back. Liebherr shows up where an architect specified the refrigeration rather than the homeowner choosing it.
Knowing which suite you are standing in front of is genuinely useful before the first reading — it predicts where the condenser is, whether the unit will show you a code, and how long a part will take to arrive.

Straight in through the back porch, which he appreciated. The freezer half was barely holding. He found the fan blade clipping a ridge of ice, cleared the drain trough and reset the defrost. Unhurried and careful.

Fresh food side crept up while the freezer stayed cold. The condenser was packed with dust and lint off the radiator behind it. He cleared it, checked the fan draw, and the cabinet was back down by evening.

Compact galley on Marlborough Street with about an inch of clearance either side. He got the freezer column out without touching a single cabinet, replaced the defrost heater, and slid it back square.
