Tall stainless side-by-side refrigerator with one door wide open on lit shelves of produce, jars and bottles

Independent Sub-Zero service · Lexington, MA

Built-in refrigeration, kept running

Sub-Zero columns, side-by-sides, drawer units, standalone ice machines and wine cabinets across Lexington and the towns either side of Route 2. Diagnosis first, in the kitchen, with the readings written down.

Most of the cabinets around here were fitted into runs that were sized for a different appliance. That is where the diagnosis starts.

What comes off the van

How a call runs

Three steps, in this order

  1. Two people standing at a stainless refrigerator, one holding a tablet and pointing towards the door

    01

    Describe it on the phone

    The model and serial off the plate inside the fresh-food door, and what the cabinet is doing — the temperature it holds, the noise it makes, when it started. Half the fault is usually identified before anybody is dispatched.

  2. Close-up of two hands holding a digital multimeter and pressing a red test probe against a white panel edge

    02

    Readings, not opinions

    Compartment temperatures against the set point, evaporator and condenser behaviour, defrost cycle, thermistor resistance, fan draw, door seal pull. Written down and shown to you at the end of the visit.

  3. Two hands holding a small cylindrical motor beside the plain white carton it was unpacked from

    03

    Priced before anything is opened

    The flat $95 call covers the visit and the full diagnosis and comes off an approved repair. Parts and labour are quoted from those readings, and nothing is ordered until you say yes.

What we work on

One manufacturer, four cabinet types

Sub-Zero built-ins are two sealed systems in one cabinet, which is why a freezer side can hold at zero while the fresh food side drifts into the forties. The work here is refrigeration work: sealed-system diagnosis, defrost and airflow, condenser and evaporator fans, thermistors and control boards, door seals and hinge geometry, ice-maker plumbing and harvest gear.

500 and 600 series
The cabinets already in most Lexington kitchens. Defrost heaters, drain-line ice, evaporator fans and tired door gaskets are the usual four.
700 and 736 drawers
Undercounter refrigerator and freezer drawers, plus the drawer ice makers that share their plumbing.
Column and integrated
Panel-ready refrigerator and freezer columns, often paired, where a removal means clearing the panel and the trim before anything else.
Wine storage
Dual-zone cabinets, glass-door heaters, zone sensors and dampers, rack hardware.

Factory-approved parts where they exist for the model, and the fault explained in the order the readings came in.

Reviews

What people said afterwards

5 out of 5 from 768 reviews

  • Ice cream going soft although the display still read zero. The sensor had drifted several degrees. He recalibrated it, then stayed to watch a full cycle rather than take my word for what it had been doing.

    Roland D. · Belmont

  • Bar machine at the island end was short cycling and running loud. Its condenser filter had never been pulled since installation and was a solid mat. Cleaned, fan checked, and production back to a full bin.

    Ibrahim N. · Meriam Hill

  • Humid stretch in July and the built-in up on Belmont Hill ran nonstop with hot air pouring off the lower grille. The fan blade was cracked and out of balance, and half the coil was furred over besides. He replaced the blade and cleaned it down, and it cycles normally again.
