Sub-Zero Repair Sammamish: Not-Cooling and Sealed-System Work
When a built-in Sub-Zero stops holding temperature, the cause is found under gauges before anyone mentions a price — and if the word is "compressor", you see the repair and the replacement side by side before you spend anything either way.
- Sealed-system diagnosis under gauges
- Visits 8 am to 8 pm · phone answered 24/7
- $89 service call, credited to the repair
Why it stops cooling
Four reasons a Sub-Zero stops cooling
A warm cabinet traces back to one of four places in the circuit. The numbers on the drawing match the cards, and the diagnosis visits them in this order: cheapest to put right first.
-
The condenser cannot get rid of its heat
Room air drawn through the grille carries heat off the condenser. Dust on the fins, trim across the grille or a stopped condenser fan cuts that air, and the cabinet warms while everything else seems to work. It is checked first on a warm unit because it is the cheapest to put right.

-
The evaporator fan has stopped moving cold air
The evaporator can be ice-cold while the cabinet warms if the fan that pushes air across it has stopped. A fan motor is one of the smaller jobs on the price list, and a quiet cabinet with the compressor running is a common clue.

-
The evaporator has frosted over
A heater clears frost from the evaporator at intervals. When the heater, the thermostat that ends the cycle or the sensor fails, frost builds until air can no longer pass the coil, and a sheet of it on the rear wall inside the freezer is how it often shows.

The sealed system has lost its grip
When the compressor stops pumping, or refrigerant has leaked away, no amount of airflow helps. It is the costliest of the four and the only one that takes gauges to prove, which is why it is diagnosed last and quoted in writing.

Repair or replace
Three situations that come up on the plateau
Each one is set out as two columns, repair and replacement, with what each involves and when each wins. No verdict — the choice stays yours.
$1,460–$3,380 sealed-system repair $11,550–$20,400 new built-in, unit only
- 01 The compressor has failed at twenty years Past the factory sealed-system cover, in a cabinet that may or may not deserve a new pump. Both columns
- 02 A remodel is on the calendar Carry the old unit through the work, or let the new kitchen decide for you. Both columns
- 03 One of a matched pair has failed Repair the one, replace the one, or replace both so the pair still matches. Both columns
The repair figure is from Sub-Zero Repair Sammamish's own price list and is agreed in writing before anything is opened; the replacement figure is a market reference for a comparable built-in, before installation and cabinetry work.

Why this shop
Built for the call that says "compressor"
Plenty of Sub-Zero calls end at a fan or a sensor. The ones that do not need gauges, refrigerant handled under EPA Section 608 certification, and someone willing to set a repair figure beside the cost of starting over.
- Sealed systems are the core of the work Compressors, leaks and refrigerant charge are read under gauges and repaired here, and refrigerant is handled under EPA Section 608 certification.
- One brand, built-in only Sub-Zero columns, drawers, undercounter units and wine storage. No dishwashers, no laundry, no other makes of refrigerator.
- The figure comes before the screwdriver $89 covers the diagnosis and is credited to the repair; the repair itself is agreed in writing before a panel comes off.
- On the plateau since 2019 The business holds a licence and carries a bond and insurance. Ask when you call and the licence number is given to you, spoken or in writing.
How a visit goes
Describe it, find it, fix it
The order does not change between a fan motor and a new compressor: the cause first, then one figure you agree to, then the work.
-
01 Say what it is doing
Read the model and serial from the tag inside the unit, then describe what it is doing and since when. That is often enough to know which parts to bring along to the first visit.
-
02 Find the cause in the kitchen
Cabinet and evaporator temperatures logged, the defrost circuit run through, fans and door seals checked, and the sealed system read under gauges when the signs point there. You hear the cause, not a hunch.
-
03 Repair it, then show the readings
Once you approve the figure the repair goes in and the unit is brought back down to temperature, and the readings are shown to you before anyone packs up.
The $89 visit comes off the repair bill in full when you say go ahead.

4.9 / 5523 reviews
After a power cut up here the temperature began swinging several degrees a day. He read the control board, found a thermistor drifting badly, and changed that rather than the entire board. Rock steady since.
Odette L.TrossachsAug 2025 Cubes were coming out hollow and then fusing into one lump. The inlet screen was half blocked, so the fill tube kept freezing. Screen cleared, tube heater replaced, and he stayed for two harvests.
Winnie F.SahaleeSep 2025 Water kept collecting under the crisper drawers and I was mopping every third day. The defrost drain had plugged with sludge. He cleared it, flushed it, then ran a whole cycle while I watched. Bone dry since.

Why Sammamish Ice Makers Scale Up and Seattle's Don't: 3 to 6.5 Grains of Well Water on the Plateau
Sammamish Plateau Water draws mainly from its own groundwater wells and reports a blended hardness of about 3 to 6.5 grains per gallon, several times Seattle's surface supply, so mineral scale is the default first hypothesis for a slow Sub-Zero ice maker anywhere on the plateau. Read it -
Sub-Zero Wine Cooler Zones Drifting Apart: What to Check
When the upper zone of a Sub-Zero wine unit holds and the lower one will not come down, the cause is usually airflow, a tired door seal or a single failed sensor — not the compressor. Here is how to tell which. Read it
Before you call
Asked on the phone
Anything else, ask when you ring. A question costs nothing; only a visit carries the service call.
(425) 610-8986What is included in the $89 visit?
The drive to your kitchen and a complete diagnosis: temperatures logged, fans and defrost tested, and gauges on the sealed system when the signs lead there. Say yes to the repair and all $89 is taken off its price. Book with Sub-Zero Repair Sammamish on (425) 610-8986.
Is a twenty-year-old built-in Sub-Zero worth repairing?
It depends on the cabinet, not the birthday. A compressor is a smaller bill than a new unit plus cabinet work, and it is worth paying when the doors seal, the control behaves and the compartment is dry. Sub-Zero Repair Sammamish puts the repair figure in writing first.
Do you repair compressors and refrigerant leaks?
Yes. Sealed-system work, meaning compressors, leaks, restrictions and recharges, is the core of what Sub-Zero Repair Sammamish does, and refrigerant is handled under EPA Section 608 certification. One firm figure from the compressor and sealed-system band is agreed before anything is opened.
When is the phone answered, and when do visits happen?
The line is answered 24/7, so a unit that quits after dinner is logged that evening. Visits run from 8 am to 8 pm every day of the week, and the booking page shows the slots still open. Sub-Zero Repair Sammamish, (425) 610-8986.
The unit is still under warranty. Who should I call?
Call Sub-Zero first. Its residential warranty covers the whole unit for two years from installation and the sealed system for five, and that work should cost you nothing. Sub-Zero Repair Sammamish is independent, so we take over once the warranty has run out or when you want a second opinion.
Which parts of Sammamish do you cover?
All of it. Klahanie, Pine Lake, Sahalee and Trossachs each have a page of their own, and every other street on the plateau is booked the same way. Tell Sub-Zero Repair Sammamish your neighborhood when you call (425) 610-8986; it helps plan the day's route.
