Wolf cooking appliance repair for Northeast Florida

One marque, one discipline, one region. Hearth & Range Service Co. repairs Wolf ranges, rangetops, cooktops, wall ovens, convection steam ovens, warming drawers and ventilation — the built-in cooking equipment in a kitchen, and nothing else in the house. Not heating, not air conditioning, not refrigeration.

One cabinet, two entirely different machines

A dual-fuel range is a gas cooktop sitting on top of an electric oven. Two tiers of sealed burner ports, a spark module and a gas train above; a resistive element, a convection fan and a control board below. They share a fascia, a badge and almost nothing else — which is why an oven that runs cool and a burner that keeps clicking are usually two separate repairs, and why being told they are one is the fastest way to pay twice.

We are independent — no factory appointment, no network scorecard — and we work 40 miles by road out from Fruit Cove, St. Johns County, Florida, which takes in Duval, St. Johns and Clay counties. Town by town, that is where we go; appliance by appliance, it is what we fix.

Monday to Friday 8am to 6pm, Saturday 9am to 4pm. Closed Sunday. · $80 flat diagnostic, credited toward the repair · 90 days labor · 365 days parts

A dual-stacked sealed burner from above: an outer ring of ports for output, an inner ring for a low simmer, one cap over both, and the electrode that has to see the flame it just lit. When it cannot see it, it clicks. Why that happens.

Cooking appliances only

We work on cooking equipment: ranges, rangetops, cooktops, wall ovens, convection steam ovens, warming drawers, coffee systems, microwaves, vacuum-seal drawers, ventilation hoods and outdoor grills. Wolf does not build refrigeration — that is Sub-Zero, a sister brand under the same parent — so a refrigerator call is not one we take.

That focus is deliberate. Built-in cooking equipment is a different discipline from general appliance work: the ovens are heavy and cabinet-mounted, the ventilation is ducted through the structure, the steam equipment is plumbed, and half the faults we are called for turn out to be the installation rather than the appliance. Doing one thing means we recognise those patterns on arrival.

What we are not

We are a built-in kitchen appliance shop and nothing else. Heating, air conditioning and the ducted system that warms and cools the house are not work this company does — no furnaces, no heat pumps, no mini-splits, no air handlers, no thermostats. That is licensed mechanical work and it belongs to an HVAC contractor. The only duct we ever open is the run that carries cooking smoke out of a kitchen hood, which is kitchen exhaust and has nothing to do with the air handler.

  • Furnaces and heat pumps
  • Central air conditioning and air handlers
  • Mini-splits and thermostats
  • The home’s HVAC duct system
  • Water heaters and plumbing
  • Refrigeration, laundry and dishwashing

We spell that out because the word Wolf on this site means the American kitchen appliance manufacturer and the cooking equipment it builds — a range in somebody's kitchen, not a boiler in somebody's garage. If what you need is a furnace, a heat pump or an air handler seen to, ring an HVAC contractor rather than us; we would only cost you a diagnostic fee and a wasted afternoon.

How a diagnosis actually runs

The order we check things in, and why that order

Almost every expensive mistake in this trade comes from diagnosing in the wrong sequence: condemning a part before establishing that the appliance was being fed properly, or replacing an element that failed because of something upstream of it. The sequence below is front-loaded with the things that cost nothing to check.

It is also why we ask what you observed rather than what you concluded. A cooktop fault and an oven fault on the same range are usually two unrelated repairs on two unrelated systems, and nothing about the appliance tells them apart for you.

  1. Reproduce the fault. Nothing is diagnosed from a description — sometimes that means waiting for an oven to reach setpoint, or running a convection fan until it is hot enough to make the noise.
  2. Check the supply before the appliance. The circuit behind it, dedicated or shared, and the gas supply at the appliance. Anything fed marginally produces intermittent faults that imitate a failing control board.
  3. Then everything mechanical you can see and feel. Door seal and hinge geometry, burner caps flat and ports clear, baffle condition, the damper and the duct run. These are the faults most often misread as electronic.
  4. Then measure. Sensor resistance against temperature, element continuity, spark and valve behaviour, what the board is switching. A meter reading is evidence; a symptom is a starting point.
  5. Then, and only then, price a part. With the model and serial number, because the correct component here frequently depends on the serial break rather than the model alone.

Where a part has to come in rather than off the van, we say so at the estimate and give you the honest lead time. Built-in equipment is worth repairing far longer than freestanding equipment — it is joinery as much as machinery, and replacing it usually means replacing cabinetry — but that only holds if the diagnosis was right the first time.

What we fix

How a visit works

$80 flat diagnostic, credited toward the repair. You get a written estimate covering parts and labor, and nothing is ordered or replaced until you have said yes to it.

Labor is warranted for 90 days and parts for 365 days. We fit genuine OEM parts.

Monday to Friday 8am to 6pm, Saturday 9am to 4pm. Closed Sunday. No 24-hour or emergency service — we would rather tell you that now than at nine in the evening.

What it costs

What does a repair usually cost?

Every call starts at the same flat $80 diagnostic, credited toward the work once you approve it. The bands below cover part and labor together.

Typical repair bands, parts and labor together.
What gets put right Typical range
Diagnostic visit $80 flat
Igniter or spark module replacement $210–$500
Burner valve or orifice service $220–$690
Oven thermostat or temperature sensor $190–$520
Convection fan or motor $260–$660
Control board or touch panel $440–$1,050
Door hinge, glass or seal $200–$690

A range is the honest answer before the panel is off; the firm figure goes in the written estimate, before anything is ordered. 90 days labor · 365 days parts. The whole table, and what the diagnostic buys.

Straight answers

The questions we are asked first

What does a visit cost?
A flat $80 diagnostic covers the visit and the diagnosis anywhere in the service area, and it is credited toward the repair once you approve the work. You get a written estimate before anything is ordered or replaced. Labor is warranted for 90 days and parts for 365 days. We fit genuine OEM parts.
Do you work on refrigerators?
No. Wolf builds no refrigeration — that is Sub-Zero, a sister brand under the same parent — so our scope is cooking equipment only: ranges, rangetops, cooktops, wall ovens, convection steam ovens, warming drawers, coffee systems and ventilation.
Do you do heating or air conditioning?
No. Hearth & Range Service Co. is a kitchen shop: built-in cooking appliances, 40 miles by road out from Fruit Cove, St. Johns County, Florida. Furnaces, heat pumps, mini-splits, air handlers and the ducted system that heats and cools the house are licensed mechanical work and we do none of it. The only duct we open is the kitchen hood's, and it goes straight outdoors.
Are you part of the manufacturer service network?
No, and we say so on every page. Nobody at the plant appointed us or vets us, and we hold no manufacturer programme of any kind. We name Wolf only to identify the appliances we service; the formal statement of our standing is in the footer.

  • Temperature was swinging forty degrees either side of the setting. The sensor probe had drifted badly out. He fitted a new probe, verified it against his own gauge, and left the oven holding within a few degrees.

  • The control knob had lost every marking and the drawer ran hotter each time we used it. He replaced the thermostat and the knob together, then verified the settings against a thermometer at three points.

    Evander Z.2026-07-17

  • Salt had seized the knob shafts so badly that two of them turned together as one. He pulled the valves, cleaned and regreased every one, and refitted the bezels straight. It feels like a different range.
