Built-in refrigeration, and nothing else
A built-in column is joinery as much as it is an appliance. It was fitted before the counter went on, it shares a cabinet run with things that cannot get wet, and pulling it forward is a half-day job on its own. That is why the diagnosis has to be right before anything is unscrewed.

It held around twenty and went no colder. He measured across the evaporator and found the fan turning slow on a failing motor. Replaced it, then stayed to watch the pull down before leaving.

Nothing at all after a full day. He found the module motor seized so the harvest never completed. New module, and he ran three cycles in front of me before packing up his tools.

Musty smell and damp inside even though the display looked normal. The drain pan had cracked and the coil was sweating onto the base. New pan, a full cleanout, and the smell has gone.

What a call looks like
One
Model and serial off the plate inside the door, what the display is showing, and when it last held temperature. Ten minutes on the phone decides which parts ride out with the van, and that is the difference between one visit and two.
Two
Compartment temperatures against a calibrated probe rather than the panel, evaporator and condenser behaviour through a full cycle, fan and defrost circuits under load, and the control board only once the mechanical side has been cleared.
Three
You hear the fault, the part, and whether the rest of the unit justifies the work. Factory-approved parts where they exist. If the sealed system has gone on an older cabinet, you will be told that plainly instead of being sold a compressor.
Why the brand matters here
Most refrigerators run one compressor and share the cold. A Sub-Zero column runs two sealed systems, so the fresh food side can drift warm for a fortnight while the freezer stays hard and nobody notices until the milk turns. The complaint that arrives is "it is not cold enough". The fault is almost never in the compartment being complained about.
The same is true of the magnetic door seal, the anti-condensation heaters around the frame and the vacuum condenser. Each of them changes the way the unit behaves without ever throwing a code. Reading the panel and stopping there is how a two-hundred-dollar gasket becomes a compressor quote.
The whole book of work
Where the van goes
Newton Centre 02459 Large shingle-style and colonial revival houses around the Green Line loop and Crystal Lake, most built between 1890 and 1930 and renovated at least twice since. Kitchens are typically rear additions with full-height built-in refrigeration set into custom cabinetry. 
Oak Hill 02459 Newton's most suburban corner, with mid-century ranches and split-levels on wide lots south of Route 9. Kitchens here are usually original-footprint remodels, where a built-in has been fitted into a wall that was framed for a freestanding refrigerator. 
Belmont 02478 From the estate houses on Belmont Hill down to the Waverley and Cushing Square two-families, the housing spans a full century. The hill kitchens often carry paired refrigerator and freezer columns, while the older houses run a single built-in in a tight back kitchen. 
Newton Highlands 02461 Newton Highlands is a walkable village of Queen Anne and Colonial houses packed close around the Green Line stop. Renovations here tend to keep the original footprint, so a full-size professional range goes in where a narrow stove used to be. Ten minutes on the phone with the model number decides which parts ride out with the van. The service call is flat $95 and it comes off the repair.
