What we service

Every Sub-Zero appliance we repair across Los Angeles.

Sub-Zero builds refrigeration only, so this is the whole range — and each one links through to how that repair actually goes.

Sub-Zero Refrigerator Repair

Built-in columns, side-by-side and panel-ready cabinets

Full-height columns and the classic 36″ and 48″ cabinets, most running a separate sealed system for each compartment. The unit comes out of its surround before most of the work starts.

  • Sealed system and compressor
  • Evaporator and defrost
  • Panel and hinge alignment

Sub-Zero Freezer Repair

Columns, drawers and integrated compartments

Frost on the back wall, a drawer that will not seal, a compartment running a few degrees warm. The defrost circuit and the gasket get checked before anything is condemned.

  • Defrost heaters and bimetals
  • Drawer seals and runners
  • Thermostats and sensors

Sub-Zero Wine Storage Repair

Single and dual-zone cabinets

A cabinet sitting two degrees off its set point is worth fixing quickly. Usually the zone sensor, the damper or the evaporator fan rather than the compressor.

  • Zone sensors and dampers
  • Evaporator fans
  • Door seals and UV glass

Sub-Zero Ice Maker Repair

Standalone and in-cabinet ice machines

Water supply gets checked before the module does. Inlet valves, fill tubes and pressure at the saddle valve account for most no-ice calls.

  • Inlet valves and fill tubes
  • Harvest and ejection
  • Drain and reservoir

Sub-Zero Beverage Center Repair

Under-counter, island and bar refrigeration

Small cabinets working hard in a confined space. Ventilation and a clean condenser decide how long they last, and the drawer runners take real abuse.

  • Condenser airflow
  • Thermostats and sensors
  • Drawer seals and runners

Sub-Zero Panel-Ready and Integrated Installs

Flush-fit units behind cabinetry panels

Cosmetically invisible and mechanically unforgiving: a cabinetry panel loads the hinges, and an alignment that has drifted shows up as a seal that will not hold.

  • Hinge and panel alignment
  • Gasket sets
  • Flush-fit adjustment
What goes wrong

Sub-Zero problems we repair across Los Angeles.

What people call us about, and what each one usually turns out to be. Nothing is named as the fault until it has been proven at the part.

Sub-Zero not holding temperature

Sealed system

A cabinet that drifts a few degrees and will not come back. Read against the sensor and put on gauges before anything is named as the fault.

Thermistors Control board Charge check

Sub-Zero fridge warm but freezer cold

Airflow

Two separate sealed systems, so one side can fail while the other holds rock solid. Usually that side’s evaporator, its fan or the defrost circuit.

Evaporator fan Defrost circuit Air damper

Sub-Zero sealed system or refrigerant leak

Sealed system

The expensive end, and the one worth proving rather than guessing. Leak traced, repaired and recharged to the original specification.

Leak trace Filter drier Recharge

Sub-Zero freezer frost build-up

Defrost

Frost on the back wall points at the defrost heater, its bimetal or the control — or at a door seal letting humid room air in.

Defrost heater Bimetal Door gasket

Sub-Zero running constantly

Condenser

A condenser packed with dust, or a fan that has stopped. On a built-in all the heat leaves through the top grille, so a blocked one is fatal.

Condenser clean Condenser fan Grille airflow

Sub-Zero cycling on and off

Controls

Short-cycling is usually the start relay, the overload, or a board calling for cooling the sealed system cannot deliver.

Start relay Overload Control board

Sub-Zero compressor not running

Sealed system

Start relay, overload, or the compressor itself. The relay is the cheapest of the three and gets ruled in or out first, because that is the honest order.

Start relay Overload Compressor test

Sub-Zero ice maker leaking or overflowing

Water

Water supply before module. The inlet valve, the fill tube and pressure at the saddle valve account for most of these.

Inlet valve Fill tube Water line

Sub-Zero ice maker freezing over

Water

A fill tube frozen shut, or a harvest cycle that is not completing. These modules get replaced far more often than they have actually failed.

Fill tube heater Harvest cycle Module test

Sub-Zero water dispenser not working

Water

Dispenser switch, inlet valve, or a line frozen inside the door. The door is where most of these faults live.

Dispenser switch Inlet valve Door line

Sub-Zero wine cabinet not cooling

Wine storage

Two or three degrees off a set point is usually the zone sensor, the damper or the evaporator fan rather than the compressor.

Zone sensor Damper Evaporator fan

Sub-Zero display or control panel dead

Electronics

Read, not guessed. Some indicators are scheduled reminders rather than faults, and a code narrows it to a circuit that still has to be proven.

Why MKH

What makes a Sub-Zero repair hold.

Plenty of shops will turn up. These are the parts of the job that decide whether the repair actually holds.

High-end appliances are what we do

Sub-Zero, Viking, Wolf and Thermador are built differently from mass-market machines, and they fail differently. These are the units our techs are on every day, so the fault gets recognized rather than hunted for.

Warranty of up to a year

Parts and labor are covered for up to twelve months depending on the repair, and the term is written on your invoice rather than left vague.

Original OEM parts

Parts that match the original specification. A cheaper substitute in a sealed system is how a one-visit repair becomes three.

$99 service call, waived with the repair

The visit costs $99. Go ahead with the repair on that same visit and the fee comes off the bill, so the diagnosis is effectively free. Decide not to, and you have paid $99 for a straight answer and owe nothing further.

A written quote before anything is touched

You see the price and approve it first. No work starts, and nothing is ordered, until you have said yes.

Same-day visits

Most calls across the Valley get a technician out the same day, and anything leaking or unsafe goes to the front of the run.

Licensed, verified and insured

BHGS #50900 for Major Appliance Repair, independently confirmed by Yelp. Fully insured, so a mistake in your kitchen is our problem and not yours.

We leave the kitchen as we found it

Floors protected, the unit back on its rails, and the packaging gone with us. A built-in has to come out before most repairs can start.

From the first call to the final test, every step is built around your time and your kitchen.

Common questions

Sub-Zero repair questions: cost, parts and warranty.

The things people ask us most, answered plainly. If yours is not here, phone and ask.

(213) 523-3555
Are you an authorized Sub-Zero service center?
No. MKH Appliance Repair Inc. is an independent repair company with no affiliation to Sub-Zero, Inc. and no authorization from them, and we are not a factory service provider. What that means for you in practice: we work on out-of-warranty appliances, we set our own prices, and we are not restricted in which Los Angeles neighborhoods we will drive to.
How much does Sub-Zero repair cost in Los Angeles?
The visit is $99, and it comes off the bill if you go ahead with the repair on that same visit. The repair is quoted in writing before anything is touched. The common jobs — a fan motor, a defrost component, a gasket set, a control board — sit far below what one of these units costs to replace, and replacing a built-in means cabinetry work as well.
Do you use genuine Sub-Zero parts?
We fit Original OEM parts — components that match the original manufacturer specification, not a cheaper substitute. We are not a manufacturer parts distributor and we do not claim to be. In a sealed system in particular, the wrong part is how a one-visit repair becomes three.
My unit is over twenty years old. Is it still worth repairing?
Usually, yes. These cabinets were designed to be opened up and rebuilt, which is exactly why so many of them are still running in Los Angeles kitchens. The honest exception is a sealed-system failure on a unit that has already had one — we will tell you when that is where you are.
Do you repair wine storage and under-counter units too?
Yes. Wine cabinets, under-counter refrigeration, refrigerator and freezer drawers, ice machines and beverage centers are all routine work.
The condenser or service light came on. Is that a breakdown?
Often it is not. Several of these indicators are scheduled reminders — the condenser wants cleaning, or a filter is past its interval. Call and describe what is lit before you assume the worst; it may be a maintenance visit rather than a repair.
Does the appliance need to go anywhere to be repaired?
No. Every job happens in your home. We are a mobile service and we have no walk-in location, which is the normal arrangement for built-in refrigeration — these units are not something you take anywhere.
My Sub-Zero is still under manufacturer warranty. Can you work on it?
No, and you should not want us to. If the appliance is still covered, the manufacturer's own authorized network should do the work at no cost to you. We handle appliances that are out of warranty.
How long does a repair usually take?
Most are finished on the first visit, in sixty to ninety minutes. Where a model-specific board or a sealed-system component has to be ordered, it is a second visit, and you will know that at the point you approve the quote rather than afterwards.
Which areas do you cover?
53 cities and neighborhoods across Los Angeles and the Conejo Valley, from the Conejo Valley to the coast. The full list is further down this page.
