Freezer Repair

Frost build-up, failed defrost parts and temperature drift on Sub-Zero freezers and freezer drawers.

Two compressor domes in the open lower machine compartment of a built-in unit, manifold gauges laid across the frame and a hand at the service valve between them

What people describe when they call

  • Ice sheeting across the rear panel until the drawer will not close
  • Freezer holding in the teens instead of near zero
  • Compressor running without ever resting between cycles
  • Food taking on freezer burn within a week

Any one of these is diagnosable on the first visit. The $89 service call covers finding out which it is.

What it costs

A range before anyone opens the cabinet.

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

Door gasket or seal replacement
$260–$700
Evaporator or condenser fan motor
$320–$740
Defrost heater, thermostat or sensor
$280–$680
Ice maker, water valve or supply line
$300–$860
Electronic control board
$430–$1,010
Compressor or sealed-system repair
$1,370–$3,080

Each line is a range because two cabinets with the same symptom rarely need the same part. What you get on the day is one figure for your unit, agreed with you before any work starts and before anything is dismantled — and the service call above is credited against it the moment you approve.

For scale: a comparable built-in replacement, before installation and cabinetry work runs $12,140–$22,020, which is why even sealed-system work is usually the cheaper road.

How the call runs

  1. You describe the symptom What the display says, what the cabinet feels like, and when it changed. Half the diagnosis is in the description, and it decides which parts ride along.
  2. A slot, not a window all day Visits run 8:00 am – 8:00 pm, seven days. The phone is answered around the clock, so an overnight failure is on the board before the crew starts.
  3. The $89 diagnosis Temperatures at both circuits, pressures where they matter, and electrical checks on the suspect part. The fee is credited against the repair.
  4. A price before anything comes apart You hear what failed, what it costs to put right, and what happens if you leave it. Nothing is dismantled on an unknown number.
  5. Verified, then put back The cabinet is brought back into range and watched through a cycle before the technician leaves, and panel-ready joinery goes back the way it came out.

  • Ice built into a sheet across the back of the freezer, which is odd in air this dry. Failed defrost heater. He replaced it, cleared the drain, and explained why the frost comes back if it clogs.

    Delaney H.Cherry Creek

  • Scrape-off duplex, tiny kitchen, and the undercounter freezer drawer kept refreezing into a solid block. Drain heater had quit. He worked in a space barely wider than the drawer and did not mark the cabinets.

    Bridger W.Highland

  • Our kitchen faces west and bakes all afternoon, and the freezer had been running near fifteen degrees for weeks. A tired compressor start relay was the culprit. Replaced, then he watched a full cycle before leaving.
