Freezer Repair

Defrost faults, frost build-up and temperature drift on Sub-Zero freezer columns, drawers and built-in freezer sections.

$89 service call covers the visit and the diagnosis, credited against an approved repair.

What people describe when they call

  • Sheet ice across the rear evaporator panel
  • Freezer sitting in the teens instead of near zero
  • Drawer no longer closing flush, with frost forming around the opening
  • Food shrinking and drying out, a sign air is not moving

What it usually is Frost you can see is an airflow story. A defrost heater or sensor that has stopped working, a drain line frozen solid, or a gasket that has gone hard in the dry air and stopped sealing. The compressor is rarely the answer here.

On the visit itself

  1. Rear panel off where the frost is, so the evaporator and defrost heater are seen rather than inferred
  2. Defrost heater resistance and sensor readings taken cold, then a forced defrost watched through to completion
  3. Drain line cleared and traced to where it empties, since a refreeze there brings the fault straight back
  4. Drawer alignment, hinge sag and gasket compression measured — the frost-at-the-opening cause

What it costs

The six bands a quote comes from

Once the readings are in, a freezer repair lands in one of these six. You are told which band it is, and the firm number inside it, before anything is opened up or ordered.

Service call

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

The repair itself is one firm number from inside the relevant band, agreed with you before any work starts. Approve it and the service call comes off the total; decline it and the visit is the whole of what you have paid.

Repair Parts and labour, fitted

These are ranges, not starting prices. What moves a job inside its band is the part itself and how far the cabinet has to come out of its joinery. For scale, a comparable built-in replacement, before installation and cabinetry work, runs $12,600–$23,120 — which is the comparison worth making before you decide either way.

  • Freezer drawers stopped closing flush and a rim of frost built up around the opening. Hinge had sagged and one corner of the seal was crushed. Adjusted and replaced, with no upsell attempted.

  • Freezer went warm every afternoon, when the west sun hits that wall of the house. Airflow was choked behind the toe panel and a vent had iced shut. Better since, but I waited five days.

    Stellan L.Park Hill

  • The freezer half of our paired columns crept up into the teens and everything inside fused into one lump. Defrost heater had gone open circuit. Replaced, and he stayed to watch it recover.
