Freezer Repair

Frost sheets, soft ice cream and drawers that will not seal on Sub-Zero freezer columns and drawer units.

What people describe on the phone

  • Thick frost building on the back wall within a week of defrosting it
  • Ice cream going soft even though the display still reads 0°F
  • Freezer drawer springing back open or icing to the frame
  • Compressor running constantly and the kitchen feels warm beside it

What the assessment covers

Cabinet and evaporator temperatures logged, the defrost circuit run through a full cycle, airflow and door seals checked, and the sealed system read under gauges when the symptoms point there. It ends with the actual cause and a firm parts-and-labour figure to put it right — the ranges further down are what that work has come to on Sammamish kitchens.

What it costs

Repair prices on the plateau

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

Below is what the work itself has come to on Sammamish kitchens, as ranges rather than single numbers. After the diagnosis you get one firm parts-and-labour figure for your own unit, in writing, before anything is opened up — and once you have agreed it, that is the figure on the invoice.

Door gasket or seal replacement
$300–$630
Evaporator or condenser fan motor
$330–$720
Defrost heater, thermostat or sensor
$300–$690
Ice maker, water valve or supply line
$260–$740
Electronic control board
$400–$940
Compressor or sealed-system repair
$1,460–$3,380
Replacing the unit insteada comparable built-in replacement, before installation and cabinetry work
$11,550–$20,400

Where a job lands inside its range is decided by the part your model takes, whether the unit has to come out of its cabinetry to reach the fault, and whether a component has to be ordered against your serial number. If the repair is not worth it against the value of the unit, you will hear that first.

  • Frost kept coming back and two earlier visits by somebody else only ever scraped it away. This time the drain trough was iced solid and the door sat a hair out of square. Both put right.

  • A sheet of frost on the back wall days after I defrosted the whole thing by hand. He metered the defrost heater, found an open circuit, and had the replacement on the van. None since.

  • Freezer was frosting over every couple of weeks. He traced it to a defrost terminator rather than just scraping the ice out and calling it done. Six months on, no frost at all.
