Viking Range Repair in Johns Creek, GA
Bozmanfix repairs Viking ranges throughout Johns Creek — Professional 5 and 7 Series in 36, 48, and 60 inch widths, all-gas VGR configurations and dual-fuel VDR models, plus Tuscany and 3 Series units, installed in the estates along Medlock Bridge, Abbotts Bridge, and the Technology Park corridor. Viking is a mechanical machine before it is an electronic one, and that shapes every diagnosis: heavy brass burner valves, a glow-bar oven igniter that has to draw enough current to open the safety gas valve, an RTD probe that governs every oven temperature, and doors heavy enough that the hinges are a wear item. We carry glow-bar igniters, spark modules and electrodes, RTD probes, burner valve components, convection motors, and EOC board parts for the common Viking configurations. Same-day diagnostics Monday through Saturday.
Viking Range Repair — Johns Creek, GA
Oven igniter that glows but never lights, VariSimmer that will not hold a low flame, baking 40 degrees off the setpoint, a burner that stops re-igniting, or a door that no longer seals at the top? We diagnose Viking at the gas and mechanical level, where these ranges actually fail.
Viking owners in Johns Creek almost never bought the range for an app. They bought it for output and control: high-BTU surface burners for hard sears, VariSimmer on every burner for sauces that hold below a simmer without a diffuser, the Gourmet-Glo infrared broiler, and a build that can be serviced and kept rather than replaced. That priority is why Viking service calls here look nothing like Wolf calls. The complaints are almost always about heat behaving wrong — not about connectivity, presets, or firmware.
It also changes what a correct diagnosis looks like. Viking uses two entirely different ignition systems in one appliance: the surface burners spark, while the oven uses a glow-bar hot surface igniter. The glow bar is not just a flame source — as it heats, its resistance drops and the rising current is what physically opens the gas safety valve. As the element ages it still glows bright orange while drawing too little current to trip that valve, so the oven appears to be working and never heats. That single failure accounts for more Viking no-bake calls in 30022 than everything else combined, and it is the one most often misdiagnosed as a control board because the igniter looks perfectly healthy from the front.
Johns Creek adds its own pattern. Many of these ranges went into new construction ten to twenty years ago and have been used hard by households that cook, which puts them squarely in the window where burner valves stiffen, RTD probes drift out of tolerance, hinges sag under a 48 inch door, and gaskets take a permanent set. None of that is a failing appliance — it is a serviceable one at the age where service is what it needs. If your range is a Wolf rather than a Viking, the failure modes are genuinely different and the right page is our Wolf range repair page for Johns Creek.
Common Viking Range Failures in Johns Creek
🔥 Glow-Bar Igniter Weak — Oven Never Lights $190–$340
The number-one Viking no-heat call, and the one where judging by eye fails completely. The igniter has to draw enough current to open the gas safety valve before any gas flows: a healthy glow bar pulls roughly 3.2 to 3.6 amps, and below about 3.2 the valve stays shut no matter how bright the element looks. So you get the worst possible symptom — a range that clicks, hums, glows orange, and produces no heat at all. We clamp an ammeter on the igniter circuit and read the actual draw rather than trusting the glow, because a failing igniter and a healthy one look identical through the oven door.
🌡️ RTD Probe Drift — Oven Runs Off Setpoint $180–$320
Every oven temperature on a Viking is derived from a single resistance probe in the cavity, and it has a published spec: roughly 1,080 to 1,090 ohms at 72°F. The direction of the error tells you what is happening — a probe reading high resistance makes the oven under-heat, one reading low makes it overheat. When it drifts, the range holds a temperature confidently, just not the one on the display, and because the error is repeatable owners adapt to it for years. We measure the probe cold against spec and verify with an independent thermometer in the cavity before calibrating.
🍲 VariSimmer Will Not Hold Low Flame $220–$450
VariSimmer is the reason a lot of Johns Creek kitchens have a Viking, and losing it is the complaint owners take most personally. The flame either goes out at the low end or jumps to something closer to medium with no usable range between. The cause is usually mechanical: a burner valve whose grease has hardened over years, a partially obstructed orifice, or an adjustment that shifted. This is a rebuild-and-adjust job far more often than a parts swap, and the low-end adjustment is the part most technicians skip.
⚡ SureSpark Clicking or Failing to Re-ignite $180–$340
SureSpark automatically re-lights a surface burner if the flame goes out, and it fails in two distinct patterns. Constant clicking with every burner off is nearly always moisture or spill residue bridging a ceramic electrode — a cleaning job with no parts at all. A burner that no longer re-ignites, or one dead position while the others spark normally, points at that electrode or its lead rather than the whole spark module. We test every position before quoting a module, because a single electrode is a fraction of the cost.
🌀 Convection Motor and ProFlow Airflow $260–$460
Viking’s convection system depends on the fan moving air past a baffle that shapes the flow across the cavity. A failing motor announces itself first as noise, then intermittently, then as uneven results across racks while the oven still reaches temperature. Worth separating from RTD drift, because the two get confused constantly: a probe fault shifts everything uniformly, while airflow trouble makes one rack or one side behave differently from the rest. Different fault, different part.
🚪 Door Hinge Sag and Gasket Set $180–$480
A 48 inch Viking door is genuinely heavy, and the hinges and springs carrying it are a wear item rather than a defect. As they weaken the door hangs slightly low, stops sealing evenly at the top, and heat escapes past a gasket that has also taken a permanent set over the years. The symptoms read like a heating problem — long preheats, uneven browning, a control that never seems satisfied — while the actual fault is that the cavity cannot hold the heat it makes. Gasket work runs from about $180; hinge and spring service goes higher.
🔲 EOC Board and Intermittent Faults $380–$720
The electronic oven control manages bake, broil, convection, and the safety interlocks. Storm-season voltage transients on the north Fulton grid stress these boards over years, and the result is rarely clean: a display that goes dark and returns, a function that stops responding while everything else works, an error that clears and comes back. We verify supply voltage, connectors, and board outputs first — a corroded connector and a single failed component are both far more common than a dead board, and this is the most expensive part on the range to replace for no reason.
🍖 Gourmet-Glo Broiler Not Igniting $190–$360
The infrared broiler is a separate burner with its own igniter and safety valve, which is why a range can bake perfectly and broil not at all. Owners often assume the whole oven is failing when only the broil circuit is affected. Same diagnostic logic as the bake igniter: measure the current the igniter actually draws against the valve threshold, confirm the valve is opening, and check the burner ports before condemning anything.
Match Your Symptom to the Likely Cause
- Oven glows orange but never heats — glow-bar igniter drawing under about 3.2 amps, so the gas valve never opens. The most common Viking fault in 30022.
- Oven bakes consistently cool by 25–50°F — RTD probe reading high resistance. Repeatable error, not intermittent.
- Oven runs consistently hot — RTD probe reading low resistance. Same part, opposite direction.
- Low flame goes out or jumps to medium — burner valve grease hardened, or a partially blocked orifice. VariSimmer adjustment.
- Constant clicking with every burner off — moisture or spill residue bridging a ceramic electrode. Usually cleaning, no parts.
- One burner will not re-ignite, the others spark fine — that electrode or its lead, not the spark module.
- One rack or one side browns differently — convection motor or obstructed airflow past the baffle.
- Everything bakes uniformly wrong — RTD probe, not airflow. Uniform error points at the sensor.
- Long preheats and heat escaping at the top of the door — hinge and spring sag plus a gasket that has taken a set.
- Bakes fine, broiler dead — Gourmet-Glo broiler igniter or its safety valve, a separate circuit from bake.
- Display goes dark and comes back, errors that clear and return — EOC board, connectors, or supply voltage.
- Yellow flame tips or uneven flame ring — burner port obstruction or air shutter adjustment, usually cleaning.
🔥 Tell us whether the problem is bake, broil, or the surface burners and we narrow the fault before we arrive. On a Viking those are three separate gas circuits with their own igniters and valves — knowing which one eliminates most of the range.

Viking Range Repair — FAQ (Johns Creek)
My Viking oven igniter glows but the oven never gets hot. What is wrong?
Almost certainly the glow-bar igniter, and the reason is worth understanding: the igniter is also the switch. As it heats, its resistance drops and the rising current is what physically opens the gas safety valve. A healthy glow bar draws roughly 3.2 to 3.6 amps; below about 3.2 the valve will not open, even though the element still glows bright orange. So the oven looks like it is working and produces no heat. This is the most common Viking no-bake fault and the one most often misdiagnosed as a control board, because there is nothing visibly wrong. We measure current draw instead of judging the glow.
How much does Viking range repair cost in Johns Creek?
The $99 diagnostic is waived when you approve the repair. An RTD probe runs $180–$320, a spark electrode or module $180–$340, a glow-bar igniter $190–$340, a broiler igniter $190–$360, a door gasket from $180, burner valve and VariSimmer service $220–$450, a convection motor $260–$460, and an EOC board $380–$720. You get an exact quote after diagnosis, before any work starts.
My oven bakes about 40 degrees cool every time. Is it the control board?
Rarely. A consistent, repeatable offset is the signature of RTD probe drift, not a board fault — a failing board produces erratic behaviour, not a reliable error in one direction. The Viking RTD probe should read roughly 1,080 to 1,090 ohms at 72°F, and a probe reading high makes the oven under-heat while one reading low makes it overheat. We measure it cold against that spec and cross-check with an independent thermometer in the cavity. It is one of the cheaper repairs on the range and it restores every baking function at once.
Why does my Viking keep clicking when all the burners are off?
Moisture or spill residue bridging a ceramic spark electrode, in almost every case. The spark module reads a false signal and keeps firing. Atlanta humidity makes it worse, and so does a burner that got cleaned with too much water. Thorough cleaning and drying of the electrodes usually stops it with no parts at all — a repair some companies quote as a full spark module.
Does the oven use the same ignition as the cooktop burners?
No, and that distinction matters when you are describing the problem to us. The surface burners use spark ignition, which is why you hear clicking when you light them. The oven uses a glow-bar hot surface igniter, which produces no clicking at all and works by drawing current to open the gas valve. So “clicking” is a cooktop symptom and “glowing but no heat” is an oven symptom, and they lead to completely different parts.
I lost my low simmer — the flame either dies or jumps to medium. Fixable?
Yes, and this is a mechanical repair rather than an electronic one. Viking burner valves use a grease that hardens over years, and the low end of the range is where you notice it first; a partially obstructed orifice does the same thing. Cleaning, regreasing, and correctly adjusting the low-flame setting restores VariSimmer. The adjustment step is what most technicians skip, and it is the step that actually gives you back a usable simmer.
Is a 15-year-old Viking range worth repairing?
Usually yes, and more clearly than with a mass-market range. These are heavy mechanical appliances built to be serviced, replacement is a five-figure decision plus surround and cabinetry work on a 48 or 60 inch slide-in, and most faults at that age are igniters, probes, valves, gaskets, and hinges rather than anything terminal. We give you an honest repair-versus-replace recommendation at diagnosis, including the cases where replacement is genuinely the better call.
Which Viking series and configurations do you service?
Professional 5 Series and 7 Series in 30, 36, 48, and 60 inch widths, all-gas VGR ranges and dual-fuel VDR models, Tuscany, Virtuoso, and 3 Series units, plus rangetops with griddle and grill sections. We also service the older Viking Professional generations still working in Johns Creek homes from the original build-out.
Do you also work on Wolf and Thermador ranges?
Yes, and they fail differently enough that we keep separate pages for them: Wolf range repair in Johns Creek and Thermador range repair in Johns Creek. Wolf calls skew toward convection behaviour and controls; Thermador toward the Star burner design; Viking toward gas, mechanical, and igniter faults.
