Freezer Repair

Frost build-up, weak cooling and defrost faults on Sub-Zero freezer drawers and full-height freezer columns, including undercounter units set into island cabinetry.

Word for word

What people describe when they ring

  • Frost building on the back wall of the freezer
  • Ice cream soft although the display reads zero
  • Drawer freezer that will not close flush
  • Defrost cycling but the frost returns within days

Defrost, airflow and frost that keeps coming back after a week.

On the visit

What is actually measured

  1. Defrost heater continuity and where the cycle actually terminates
  2. Drain line clear from the evaporator tray through to the pan
  3. Evaporator fan speed and the airflow reaching the compartment
  4. Drawer runners and seal alignment on drawer freezers

What it costs

Bands, not a quote

The number depends on three things: which component failed, whether the part is on the van or has to be ordered for the platform, and how much has to come apart to reach it. These are the ranges this work falls into — the figure for your unit is quoted after the diagnosis and before anything is opened.

  • Door gasket or seal replacement $270–$740
  • Evaporator or condenser fan motor $290–$600
  • Defrost heater, thermostat or sensor $300–$670
  • Ice maker, water valve or supply line $310–$680
  • Electronic control board $520–$880
  • Compressor or sealed-system repair $1,020–$2,230

Flat $95 service call covering the visit and full diagnosis, credited against the repair once you approve it.

For comparison, a like-for-like new built-in in this class runs $8,190–$19,230 for the appliance alone, before delivery, installation, panels or cabinetry work. That gap is why a control board or a fan motor is almost always the cheaper answer — and where it is not, you will be told so.

    Compact galley on Marlborough Street with about an inch of clearance either side. He got the freezer column out without touching a single cabinet, replaced the defrost heater, and slid it back square.

    Ice cream soft although the display still read zero. The defrost thermostat had failed open. He tested it in front of me and fitted the replacement.

    The freezer drawer stopped closing flush and ice was creeping along the runner. He pulled the basket, melted the ice back properly and replaced a cracked roller. Explained why our load height made it worse.
