Sub-Zero Refrigerator Repair
Most of the Sub-Zero refrigeration in this corridor is panel-ready and built into millwork, so a repair is a repair — there is no simple swap waiting behind it. We take on sealed-system diagnosis, evaporator and defrost faults, control boards, fans, hinges and gasket replacement on both classic built-ins and the current integrated line.
Word for word
What gets described on the phone
- Temperature alarm on the display with no obvious cause
- Compartment cooling unevenly from the top shelf to the bottom
- Interior lighting out and the controls unresponsive
- Warm air you can feel at the top of the door when it is shut
Sealed system, evaporator, defrost, boards, fans, hinges and gaskets.
On the visit
What is actually measured
- Both compartments read against their set points, top shelf and bottom
- Evaporator inspected in each compartment for ice or a stalled fan
- Condenser loading and fan behaviour behind the base grille
- Door seal along its full run, plus hinge sag at the top corner
- Control board and sensor readings against the platform specification
Cost
The bands this work falls into
Three things set the figure: 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. A fan motor behind an interior panel and a sealed-system repair in the same cabinet are not remotely the same job, so what follows is a range and your number is quoted after the diagnosis.
| Repair | Range |
|---|---|
| Door gasket or seal replacement | $300–$730 |
| Evaporator or condenser fan motor | $300–$620 |
| Defrost heater, thermostat or sensor | $280–$670 |
| Ice maker, water valve or supply line | $300–$690 |
| Electronic control board | $520–$860 |
| Compressor or sealed-system repair | $940–$2,150 |
Flat $95 service call covering the visit and full diagnosis, credited against the repair once you approve it.
A like-for-like replacement is the other half of that decision: a new built-in of this class runs $8,660–$19,630 for the appliance alone, before delivery, panels, cabinetry or the fitting itself. That is the comparison worth making before a control board is written off as too expensive.

Shingled Victorian, rear kitchen, and a doorway that barely takes a column. He got it out on straps without marking the casing. The condenser fan bearing was dry and dragging, which explained both the noise and the warmth.

Drawers set into the island of a postwar ranch up in the Heights, and the top one had stopped holding temperature at all. The gasket had rolled over at one corner and was quietly drawing warm air in. A new gasket and a hinge adjustment sorted it.

Temperature alarm on the display with nothing obviously wrong inside. He put gauges on and found a slow leak at a brazed joint rather than a board fault. Repaired and recharged, and the alarm has not come back.
