Freezer Repair

Defrost circuit, evaporator and door-seal work on Sub-Zero freezer columns and built-in freezer sections.

How it lands on the phone

  1. Solid frost slab building on the rear panel behind the baskets
  2. Freezer drifting up to 15°F and ice cream going soft
  3. Loud rattling or buzzing that stops when you open the door
  4. Door frame sweating and frost forming around the gasket

What happens on the visit

Temperatures logged at both compartments before anything comes apart, then the sealed system read under gauges and the defrost and control circuits tested in sequence. A Sub-Zero rarely fails in a way that needs guessing — it fails in a way that needs measuring.

You get the cause, the reading it came from, and a firm number for parts and labour. Nothing is opened up or ordered until you have said yes to that number. The bands that number comes from are set out further down this page.

Rest of the work

What it costs

The bands we quote from

Parts and the labour to fit them, grouped the way the faults actually arrive in Tacoma. Once the readings are in, your job sits inside one of these six.

Service call

Flat $89 service call covering the visit and full diagnosis, credited against the repair once you approve it.

You are quoted one firm number from inside the relevant band, agreed with you before a single screw comes out — and the service call comes off that number the moment you approve the work. Nothing is ordered or opened up until then.

Door gasket or seal replacement
$290–$660
Evaporator or condenser fan motor
$310–$700
Defrost heater, thermostat or sensor
$270–$680
Ice maker, water valve or supply line
$260–$780
Electronic control board
$390–$1,000
Compressor or sealed-system repair
$1,440–$3,390

These are ranges, not starting prices. What moves inside one is the part itself and how far the unit has to come out of its cabinetry. For scale, a comparable built-in replacement, before installation and cabinetry work, runs $11,550–$21,190 — which is the comparison worth making before you decide either way.

  • Door frame was sweating and frost formed around the gasket every night. He traced it to a failed door heater circuit. Arrived at the very end of the window, but the diagnosis was right.

  • Undercounter unit out on the deck stopped holding below zero. Salt air had eaten the condenser fins away. Cleaned, resealed the door, and it has held steady through a warm week.

  • Buzzing that stopped whenever I opened the freezer door. The evaporator fan blade was catching an ice ridge from a lazy drain. Cleared the drain, new blade, and the noise is gone.

it is doing

Model number and the symptom is enough to start. Most faults get named on the phone; the visit confirms it under gauges and the price is agreed before a single screw comes out. The line is answered 24/7.
