Burners that click without lighting, a simmer that won’t hold, an oven that won’t reach temperature, a griddle that heats unevenly. SAVA repairs Wolf dual fuel, gas and induction ranges, rangetops and cooktops across Chicago and the North Shore.
SAVA HVAC & Appliance Repair has repaired Wolf ranges across Chicago and the North Shore since 2017 — dual fuel DF models, all-gas GR ranges and the earlier R Series, IR induction ranges, SRT sealed burner rangetops and CG gas cooktops. Every Wolf gas cooktop is built around dual-stacked sealed burners: an upper tier of flame ports for full output, and a lower tier that turns down to less than 300 BTU for simmering. Large burners reach up to 20,000 BTU on current models and 15,000 BTU on many earlier ones. Below the cooktop, a dual fuel range has an electric convection oven, while a GR gas range has a gas oven — on 30- and 36-inch models, a 30,000 BTU bake burner and an 18,000 BTU infrared broiler. Most calls trace to ignition, the burner valves, or the oven’s heating and temperature control. Diagnosis is $79, credited toward the repair.
A Wolf burner lights when gas reaches the ports evenly and a spark jumps from the electrode at the right moment. When it clicks without lighting, one of those is missing: ports blocked by a boilover, a burner cap that is not seated true, moisture in the electrode, a cracked electrode insulator, or a spark module that has weakened. Because a dual-stacked burner has two tiers of ports, a burner that lights on high but will not hold its lowest setting points us to the lower tier or the valve rather than the spark.
Wolf’s spark ignition relights a burner automatically when the flame goes out, so clicking on a burner that is already lit means the system has lost track of the flame — moisture in the ignition circuit, a burner only partly lit around its ring, or a failing switch or module. On GR gas ranges, Wolf treats surface burners that click steadily while the oven is running as a fault that needs service, not normal behavior.
The lower tier of a dual-stacked burner is designed to run below 300 BTU. A burner that goes out at its lowest setting, or never gets truly low, usually has a burner valve that has worn, a partly blocked lower tier, or the wrong orifices for the gas supply — most often on a range that has been converted between natural gas and propane. We check the rating plate against what is actually installed.
A GR gas oven lights its bake burner with direct spark ignition, and Wolf expects it to light within about 40 seconds. Wolf’s own list of reasons it may not is specific: a dirty or defective electrode or electrode wire, a defective gas solenoid, a failed ignition (DSI) board, a defective thermostat, a loose connection, no power or no gas, or a convection fan running during preheat. We work through that list with test equipment rather than replacing parts in turn.
On a dual fuel range the oven is electric: bake and broil elements, a convection system, a temperature sensor and the control that switches them. Current dual fuel models use Dual VertiFlow convection, with fans and vertical elements working as pairs, so a failed fan or element tends to show up as uneven baking on one side before the oven stops heating altogether. An oven that runs hot or cold without other symptoms usually points to the temperature sensor or calibration.
GR ovens broil with an 18,000 BTU infrared burner, and Wolf rangetops and ranges can carry an infrared charbroiler, a griddle or a French top. On units built before serial number 18180000, Wolf rates the charbroiler at 16,000 BTU and the griddle and French top at 15,000 BTU. When one of these lights but heats weakly or unevenly, we look at the burner itself and the gas supply to it; when it will not light, the ignition side comes first.
On an IR induction range or an induction cooktop, a zone that will not heat, cuts out under load or shows an error usually traces to the power electronics that drive the coil, the coil itself, the control, or a problem detecting the cookware. We test the zone’s power stage and the control before replacing anything, because the symptoms overlap.
Smell gas? Leave the home and call Peoples Gas (866-556-6004) or Nicor Gas (888-642-6748) from outside before calling any repair company. Then call SAVA for the repair.

Wolf ranges are built heavy — cast-iron grates, commercial-weight burners, stainless cabinets — and the parts that fail are usually components: electrodes, spark modules, valves, sensors, elements, fans and ignition boards. That is why repair is the right call on most Wolf ranges we see, including ones well past their warranty. Replacement starts to make sense when the oven cavity or the gas manifold is damaged, or when several major components are failing at once. We tell you which situation you are in before any work begins.
