Sub-Zero Freezer Repair
Freezer drawers, upright freezer columns and the freezer half of a built-in unit. Frost patterns, defrost faults, blocked drains and start-up behaviour are all read from the same appliance rather than guessed at.
Flat $95 service call · credited against an approved repair
How it gets described on the phone
The complaint, in the caller's words
- Frost sheeting across the back wall within days of clearing it
- Ice cream soft although the panel still reads zero
- The drain freezing over so meltwater tracks onto the floor
- The unit starting, clicking and shutting down again within a minute
On the visit
What gets measured before anything is replaced
- Cabinet temperature against the panel reading, not instead of it
- Defrost heater continuity and terminator behaviour through a cycle
- Drain line clearance and the state of the trough beneath the evaporator
- Start-up sequence: compressor draw, relay and overload behaviour
- Frost distribution, which tells you where the warm air is entering

What these repairs come to, before you ask
Flat $95 service call covering the visit and full diagnosis, credited against the repair once you approve it.
Typical all-in totals for the repairs that come up most often out here — parts and labour together, from the low end of a straightforward job to the high end of an awkward one. Which end of a band a particular unit lands on is what the visit establishes.
- Door gasket or seal replacement $270 – $770
- Evaporator or condenser fan motor $300 – $650
- Defrost heater, thermostat or sensor $310 – $720
- Ice maker, water valve or supply line $280 – $720
- Electronic control board $520 – $900
- Compressor or sealed-system repair $970 – $2,190
Against replacing it
$8,630 – $20,330
That is the appliance alone. Set the repair band beside it before deciding — on a built-in, the cabinetry usually decides the argument rather than the compressor.
Where those replacement figures come from
A comparable built-in refrigerator, appliance only — before delivery, installation, custom panels or cabinetry work. Undercounter and wine units sit below this band; a column replacement is usually two purchases rather than one.
Four things decide where inside a band a job lands:
- Which part failed A door gasket, an evaporator fan and a sealed-system component are three different orders of job. Until the fault is found, any number would be a guess.
- Whether the part is still made Current models are straightforward. Older units sometimes need a superseded part sourced, and that changes both the price and the timeline.
- How the unit is installed A panelled column in a run of cabinetry takes longer to get at than a freestanding unit with clearance on both sides. Access is real labour.
- What else is close to failing If a second component is visibly on the way out, you hear about it while the unit is open rather than on a second call.

The drawer would not seal after we reloaded it from the garage. Rail alignment was off and one gasket corner had folded under itself. Twenty minutes of adjustment and it shuts with that suction sound again.

Meltwater was tracking onto the floor from a blocked drain line. He steamed it clear and checked the slope of the trough. Quick, clean, no upselling.

Ice cream was going soft although the panel still read zero, so I nearly ignored it. He measured real air temperature at the vent rather than trusting the display, found the defrost heater open, and swapped it. He also traced the stain that explained the smell.

Where
Sub-Zero Freezer Repair across the four towns
Each town has its own page with the housing and access notes that actually change how a call runs out there.
-
Sherborn
Sherborn holds two-acre zoning and virtually no commercial strip, so the housing runs to antique colonials and shingled custom homes set well back in the trees. Renovated kitchens often sit at the rear of the house with a butler's pantry or a second undercounter unit off to one side.
-
Medfield
Medfield pairs a compact village centre of 19th-century houses with post-war and 1990s subdivisions out toward the Charles. Kitchen work in the older centre houses tends to be a full gut with integrated refrigeration and tight galley clearances on either side.
-
Dover
Dover is large-lot country: long driveways, older farmhouses and newer custom builds spread thinly along the Charles. Kitchens are big and frequently carry a second refrigeration unit in a pantry or mudroom.
-
Westwood
Westwood mixes Islington's older village housing with wooded subdivisions off High Street. The newer kitchens are open-plan with island seating, and refrigeration is nearly always integrated behind cabinet panels.
