Sub-Zero
Independent Sub-Zero repair across St. Johns County
Sub-Zero built-in refrigeration is the most common thing we are called to in this county, and airflow is the answer far more often than the sealed system is.
Six makes
The brands we work on, and what each one actually builds.
Half the service calls that go wrong start with a brand that does not make the appliance in question. Sub-Zero builds refrigeration and no cooking equipment at all. Wolf builds cooking equipment and no refrigeration. Thermador and Viking build both. Each page below says which, and what fails on it in St. Johns County.

Wolf
Independent Wolf cooking-appliance repair in St. Johns County
Wolf builds cooking appliances and nothing else. That narrows the diagnosis usefully, and it puts the whole of the water story on the steam side of the line.
Thermador
Independent Thermador repair across St. Johns County
Thermador is the broadest line we work on, which means one house can have four Thermador appliances failing for four unrelated reasons.
Viking
Independent Viking Range appliance repair across St. Johns County
Viking Range builds professional-style kitchen equipment, and the Viking in this county tends to be twenty years old and still worth keeping — which makes parts availability the first question.
Miele
Independent Miele repair across St. Johns County
Miele builds the most fully integrated kitchen line we work on, which makes access and correct part identification matter more here than on any other make.
Bosch
Independent Bosch repair across St. Johns County
Bosch dishwashers dry by condensation rather than with an element in the tub, and that one design decision changes what a drying complaint actually means.
Why the brand names are here
Naming a make says one thing: whose appliances we repair.
Naming a make is descriptive, never a claim of approval. The affiliation statement is printed in full in the footer of every page.
St. Johns County Appliance uses no manufacturer logo, brand typeface or brand color anywhere on this site. Every brand name on it is set in the site's own faces, as plain text.
What repairs run
Does the make change what a repair costs?
The visit is $80 flat and comes off the bill. What the repair costs depends on which part failed, so these are ranges, not quotes.
| Repair | Typical range |
|---|---|
| Oven thermostat or temperature sensor | $190–$550 |
| Igniter, spark module or surface element | $190–$520 |
| Electronic control board | $400–$990 |
| Diagnostic visit, credited to the repair | $80 |
Parts are itemised on the written estimate, and nothing is fitted before you have approved the figure.
Questions
What do people ask about the makes?
- Does the brand change what a repair costs?
- Far less than people expect. The band is set by the component: a control board is $400–$990 on any of these makes, an oven sensor or thermostat $190–$550. What the brand changes is availability and how the appliance is built into the room, which is the labor.
- Do you fit genuine parts?
- Genuine OEM parts, bought through ordinary distribution. Parts are identified against the model and the serial number rather than the model alone, because manufacturers make running changes mid-production and the same model can take two different components depending on when it left the line.
- What if the part for my appliance has gone out of production?
- Then you get told before the estimate rather than after. On older equipment the parts question decides the repair, so it is checked first. Where the part is gone and no sound alternative exists, the honest answer is that the machine has no future, and it gets said plainly.
Customer feedback
Three recent calls, across the six makes
Rated 4.4 out of 5 across 100 customer reviews. Each is one visit, described by the person who paid for it.
The compressor was running without ever satisfying the thermostat. Rather than quoting a sealed system straight away he checked the controls, found a stuck damper motor and a blocked return, and it settled within a day of the fix.

The bridge zone stopped recognising anything wider than a saucepan. He tested the coils individually, found one detection sensor out of range and replaced the pair so they match, then checked the whole top with our own pans.
Seraphine R.2026-01-27
It would not start a programme at all after a power cut. He found the door interlock had failed closed, replaced it and checked the board for surge damage while he was in there. Running normally since.
