Built-in refrigeration
Built-in refrigeration repair across St. Johns County
Built-in refrigeration is repaired around a cabinet opening, not replaced out of one. That single fact changes what is worth doing when it fails.

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.
What people call us about
Symptoms we see on Thermador in this county
- Gas burner lights but will not stay on the lowest simmer setting
- Induction element cuts out under load, then resumes after it cools
- Refrigeration column runs but the freezer column beside it drifts warm
- Dishwasher runs far longer than the time it displayed at the start
- Steam oven produces visibly less steam or takes longer to generate it
- Wall oven door hinge no longer holds the door against the seal
- Hood or downdraft blower cuts out intermittently under high speed
Symptoms, not fault codes. We describe what an appliance does rather than quoting a code we have not read off your machine.
Thermador covers more of a kitchen than anything else on this site. Gas and induction cooktops, professional ranges, wall ovens, steam and speed ovens, warming drawers, refrigeration and freezer columns, wine columns, dishwashers, ventilation hoods and downdraft systems. A single St. Johns County kitchen can carry five of them, and when two fail in the same month the causes are usually unrelated. Diagnosing them as one problem wastes a visit.
Cooking side
Gas burner faults sort into three groups quickly. A burner that lights and then drops out at low flame is almost always a simmer-setting or valve-orifice issue rather than an ignition one. A burner that will not light at all, on a cooktop where the others do, is normally the igniter or its lead. A burner that lights and then relights the whole array is a spark-module fault.
The star-shaped burner ports Thermador uses spread flame further across the pan base than a ring, which is a real advantage and also means a boil-over blocks more ports at once. A large proportion of “burner is weak” calls are a cleaning job on the cap and the ports, and we would rather tell you that on the first visit than sell a part.
Induction is different: it fails by cutting out. An induction element that works from cold and stops after fifteen minutes under a heavy pan is describing a thermal shutdown, and the cause is nearly always cooling — the fan intake under the cooktop is blocked, the cavity beneath it has been closed in by a cabinet modification, or the fan itself has slowed. In coastal 32082 kitchens we also see corrosion on the power board’s connections, which is a separate story with a similar symptom.
Cold side
Thermador refrigeration columns are separate machines that happen to sit next to each other behind matching panels. A refrigerator column and a freezer column share a look, not a sealed system. When someone tells us the freezer is fine but the fridge is warm, that is not a puzzling contradiction — those are two independent units and one of them has a fault.
The plumbed ice maker inside the freezer column degrades rather than fails, and it is worth knowing why nothing ever reports it. The control runs a timed fill rather than a metered one, so anything that reduces how much water arrives in that window under-fills the mould and produces no fault code at all. Cubes get smaller, then hollow, then arrive in partial harvests as the release cycle stretches.
Since a restricted supply and a failing fill valve produce that identical progression, pressure at the appliance connection gets measured before either is quoted. On a column that connection is behind the unit, which is one more reason the access question comes first.
Dishwashers
Thermador dishwashers sort into the same four systems as any other make — the drain path, spray pressure, the heating circuit, and the door with its latch and seal — and the value is in checking them in that order rather than in the order they are guessed.
The one worth explaining is cycle length, because it is the complaint most often mistaken for a fault. A machine that displayed two hours and ran three has usually not failed. It extends the cycle rather than proceeding cold, so a long run is a report about how fast water is reaching temperature: the incoming supply temperature first, then the heating circuit, then the sensor that decides temperature has been reached. Two of those three cost nothing to check.
A top rack coming out dirtier than the bottom is a pressure symptom rather than a wash-programme one, because the top rack is furthest from the pump and shows a loss first. Spray arms that will not turn freely, restricted jets and a circulation pump losing performance are the three causes, in that order of likelihood — and loading is worth ruling out before any of them, since a sheet pan across the lower rack shadows the entire upper spray path.

Dishwasher repair, and the four systems worth checking in order
Most dishwasher calls are one of four systems, and they are worth checking in a fixed order because three of them can imitate the fourth.
Ranges & cooktops
Range, rangetop and cooktop repair in St. Johns County
Cooking appliances never meet the water supply, so their failures come from ignition, heat control, cooling airflow and the coastal and storm environment.

Every entry here was a visit to this make of appliance.
The self clean cycle would start and then abandon itself. He traced it to a door lock motor that was not driving fully home, replaced the assembly and ran a shortened clean through to prove it. No trouble since.

Our induction top kept throwing a fault and shutting the zone down. He found the underside fan intake carpeted in dust and one power board connector browned. He cleaned the intake but the board took weeks to arrive.
Lysander N.2026-05-08
Frost was building along the ceiling of the freezer drawer. He found the drawer seal folded under at one corner and the defrost sensor reading badly out. Both replaced and it has stayed clear since.
