Independent Appliance Repair · St. Johns County & Duval County
Thermador appliance repair, Northeast Florida
One manufacturer's built-in kitchen equipment, nine appliance classes, three counties. Not a town service and not a general appliance shop: Meridian Appliance Works is the Thermador specialist for the whole of Northeast Florida, and the pages here are organised by the machine in front of you rather than by where you live.
A Thermador cooktop has no burners to fix
Freedom Induction is one continuous surface with pan detection, so nothing on it corresponds to a burner and nothing on it fails like one. Faults cluster in the coil boards underneath, in the cooling fan that keeps them alive, and in the touch control interface. That is the whole argument for this company: a built-in kitchen is architecture, and it has to be diagnosed as the system it actually is.

What we work on
Organised by appliance type, because that is how these machines fail. Every page names the symptoms we hear, the parts that actually go, and the local factor that drives it.
Induction cooktops
Full-surface induction is an electronics platform under a sheet of glass. When a zone dies it is almost never an element, and diagnosis has to start at the inverter boards.
Gas rangetops
Star burners, ExtraLow simmer and a griddle or grill module in one drop-in top. Most faults are ignition, gas flow or a control that has stopped cycling correctly.
Professional ranges
One appliance doing two jobs. The rangetop half and the oven half fail in completely different ways, and a range visit has to cover both properly.
Wall ovens
Built into cabinetry, carrying a heavy door and a lot of heat. Wall ovens fail at the door, at the sensor and at whatever the last self-clean cycle pushed too far.
Steam ovens
A small water system inside an oven: fill, heat, level sensing, drain and a sealed door. Weak steam is one of those five, and they are separable in an hour.
Speed ovens
Microwave energy and convection heat in one built-in cavity, which means two heating systems, two failure sets and one high-voltage section nobody should open casually.
Column refrigeration
Panel-ready columns installed flush into cabinetry. Service starts with pulling the unit forward on its rails, and the ice maker is the assembly that fails first.
Dishwashers
Quiet, panel-ready and third-racked, which makes a fault easy to ignore. Most calls here are a machine still finishing its cycle and no longer doing the job.
Ventilation
Hoods, inline blowers and roof-mounted units. The motor is often nowhere near the kitchen, and on the coast it is sitting in salt air all year.
The kitchen is where our work stops
Meridian Appliance Works opens built-in kitchen appliances, and that is the whole list: Thermador wall ovens, steam ovens and speed ovens, professional ranges, gas rangetops, induction cooktops, refrigerator, freezer and wine columns, dishwashers, and the ventilation hung over the cooking surface.
We do not service heating, air conditioning or ductwork. No furnaces, no heat pumps, no air handlers, no mini-splits, no duct cleaning and no duct replacement — not as a sideline, and not handed to a partner firm. A house that will not warm up or will not cool down is a licensed HVAC contractor's job, and we say so on the telephone instead of booking a visit we could not finish.
The two trades share some vocabulary and nothing else. A range hood has a duct above it. A refrigeration column has a sealed system, a condenser and a condenser fan, and the ambient of the room around it — air-conditioned or not — is what that condenser has to reject heat into. All of that is appliance work, and it is where EPA Section 608 applies: it permits us to open a sealed refrigeration circuit, not to touch the building's own heating and cooling plant.
The nine appliance classes, one page each · What this company is and is not
Local factor
Power events, salt air, and how the kitchen was built
Around 68 thunderstorm days a year, plus the multi-day outages this coast took after Matthew in 2016, Irma in 2017 and Helene in 2024. Appliance electronics do not always fail on the day.
A board that saw a surge or a brownout can run for weeks and then stop, which is why we ask when the power last went out before we quote anything. A sealed-system compressor with an inverter drive behaves the same way: it restarts, it cools, and it gives up a month later. Diagnosing that as a new fault is how an owner ends up paying twice.
The other two factors are geographic. Within a few miles of the ocean, chloride reaches condenser fins, hinge hardware and roof-mounted blowers years before anything wears out mechanically. Inland, the constraint is usually the cabinetry and the circuit: a pre-war opening that was widened by hand, a column with no clearance to come forward, a hood duct with more elbows than the blower was sized for.
What a technician checks, and in what order
The order is not arbitrary. Each step either eliminates a whole class of cause or is cheap enough that skipping it costs more than doing it.
Supply first
Voltage at the appliance, the breaker, and whether the circuit is genuinely dedicated. A board replaced on an undersized or shared circuit fails again.
The complaint, reproduced
We run the appliance and watch the fault happen rather than accepting a description of it. Intermittent faults get a longer cycle, not a faster guess.
Sensors before boards
Thermistors, level sensing and door switches are cheap, measurable and fail far more often than the board reading them. A board is a diagnosis of exclusion.
Airflow and clearance
Cooling fans, vent paths, condenser access and the cabinet opening itself. An appliance closed in by joinery or a counter substrate will keep failing the same way.
Model and serial, then parts
The serial number decides which variant of a part fits. We read the data plate before we order, and we tell you the lead time in writing rather than after the fact.
Price bands
Parts and labour together, for work completed.
What does a Thermador repair cost in Jacksonville?
Between $80 and $2,420, depending which component is at fault. Before the appliance is opened a band is the honest answer; a single number is a guess in a quote's clothing.
| What turns out to be at fault | Typical range |
|---|---|
| Diagnostic visit, credited against the repair | $80 |
| Refrigeration column sealed system | $920–$2,420 |
| Control board or touch panel | $440–$1,100 |
Asked before the first call
Is the $80 diagnostic charged again if a part has to be ordered?
No. $80 is charged once; the fitting visit is the same job, and the charge is credited against the repair once you approve it. A written estimate comes before any part is ordered or fitted.
How far do you drive, and when are you open?
40 miles by road from Fruit Cove. Every distance quoted on this site is drive distance, not a straight line. We work Mon–Fri 8am–6pm · Sat 9am–4pm, by appointment. There is no night or weekend premium on this site because there is no night or weekend service to charge one for.
Do you work for Thermador?
No. Meridian Appliance Works is independent and holds no Thermador or BSH Home Appliances accreditation of any kind; the full statement is in the footer. Our one credential is EPA Section 608 certified for sealed-system refrigeration work, a federal permission rather than a manufacturer endorsement.
Do you service heating, air conditioning or ductwork?
No. Built-in kitchen appliances are the whole business: ovens, cooktops, rangetops, ranges, refrigeration and wine columns, dishwashers and the ventilation over the cooking surface. Furnaces, heat pumps, air handlers, mini-splits and duct runs belong to a licensed HVAC contractor, and we are not one.

What owners said after the visit
One visit each, in the words we were given, unflattering ones included.
The fault was cured at the second attempt. The first visit changed a part that turned out not to be the problem, and although I was not charged twice, it cost me another day at home.
Clemency A.2026-04-16
Steam was reaching temperature slowly and food came out uneven. He replaced a heating element in the generator and cleaned the outlet ports. Better, though it is still not quite as quick as it was new.
Bianca A.2025-08-21
Clicking would not stop on the right hand pair long after they had lit. He replaced a switch body that had taken moisture and it is greatly improved, although it still ticks once on damp mornings.

What we are
Stated once, in plain words, because it is the whole basis on which an independent shop is allowed to name a manufacturer at all.
Independent, and saying so first
Meridian Appliance Works is an independent service company. We name Thermador only to say which appliances we work on: built-in equipment from Thermador and the rest of the BSH Home Appliances line, diagnosed and repaired by our own technicians using genuine OEM parts.
- EPA Section 608 certified for sealed-system refrigeration work. That is a federal requirement to open a sealed refrigeration system, and it is the only certification we hold out.
- Licensed and insured in the State of Florida.
- Parts come through the same BSH Home Appliances distribution channel that serves Bosch and Gaggenau, which is why lead times on a Thermador part behave the way they do.
