Holding around twenty and going no lower no matter what I set. Thermostat read fine, so I assumed compressor and a big bill. He found a defrost cycle that ran and cleared nothing, traced it to the thermostat sensor. Relieved.

Sub-Zero repair
Built-in refrigeration that is meant to outlive the kitchen it sits in. Most of what we see is a twelve to twenty year old unit where one subsystem has aged out while everything around it is still sound.

How this one fails
What we find on Sub-Zero
Sub-Zero splits its cooling into two independent sealed systems on most built-ins, which is why a unit can hold a perfect freezer and drift warm on the fresh food side at the same time. That symmetry is diagnostic: it tells you the compressor is fine and sends you to the evaporator, its fan, and the defrost circuit that serves that half. The 500 and 600 series are still everywhere in Boston kitchens, and parts for both remain available, which is the question most owners actually want answered before they spend anything.
- Fresh food side climbing while the freezer stays cold — one of two sealed systems, not the whole unit
- Condenser packed with dust behind the upper grille, in a unit that has never had it cleared
- Defrost heater or thermistor failed, leaving a slab of ice under the lower basket
- Ice maker filling but not releasing, usually the mould heater or the harvest arm rather than the valve
- Door gaskets hardened and no longer sealing at the hinge corner, running the compressor continuously

Sub-Zero in particular towns
Where the local detail changes the job
- Newton The Newton built-ins we see are mostly 600 and Classic series in kitchens redone between the late nineties and the mid two-thousands.
- Brookline Brookline built-ins are frequently boxed into period cabinetry made to fit the appliance rather than the other way round.
- Rockport Rockport is as exposed as our coverage gets, and it shows in the condensers.
- Gloucester The most exposed condensers we service are in Gloucester.

Fridge was fine but the noise behind the cabinet panel had got loud enough to hear from the hallway. Turned out to be the condenser fan, not the compressor I had convinced myself it was. One part, one visit, no drama.

Front left burner sparked and sparked and would not catch. He checked gas first, then spark, then found the cap fouled and shorting the spark somewhere useless. Cleaned and reseated. He did not sell me an igniter I did not need.

Independent, and clear about it
We are not authorised by Sub-Zero and we do not claim to be. We fit parts made to the manufacturer's specification, we diagnose before we quote, and the $95 service call comes off the repair once you approve it.
