The short answer
Viking Repair Experts repairs Viking, Wolf and Thermador ranges in Sunnyvale, including burners, igniters, ovens, convection fans and control boards. We diagnose the cause on site, explain your options, and recommend repair only when it makes sense for your range.
When a burner won't light or the oven won't hold temperature, cooking at home gets harder fast. Viking Repair Experts repairs premium ranges in Sunnyvale homes, with a focus on Viking gas, dual-fuel and electric models. We also work on Wolf and Thermador ranges and service Sub-Zero refrigeration, so one technician can look at most of the high-end appliances in your kitchen. Sunnyvale is about 7 miles northwest of our San Jose base, and we serve homes across ZIP codes 94085, 94086, 94087 and 94089. Our goal is to find the actual cause of the problem, explain it in plain terms, and fix it with the right parts so your range works the way it was designed to.
Range Problems We Fix in Sunnyvale Kitchens
Premium ranges are built to last, but heavy use and normal wear still catch up with them. Most service calls we get involve a handful of familiar symptoms. Each one has several possible causes, which is why we test before replacing anything.
- Burners that click but won't light, or light slowly and unevenly
- Constant clicking from spark igniters after the burner is lit
- Weak, yellow or uneven flames on gas burners
- Oven that won't heat, heats slowly, or runs hotter or cooler than the setting
- Convection fan that is noisy or doesn't run
- Broil element or broil burner not working
- Oven door that won't close fully or a worn door gasket letting heat escape
- Control knobs, displays or electronic controls that don't respond
- Self-clean cycle problems or a door lock that stays engaged

How a Range Repair Visit Works
We start by asking what you've noticed: when the problem started, whether it's constant or occasional, and which burners or oven modes are affected. Those details often point to the right component quickly.
Next, the technician inspects and tests the range. On a gas model that may mean checking igniters, spark modules, burner heads, valves and the oven ignition system. On electric and dual-fuel models we test elements, sensors, relays and control boards. We look for the cause, not just the part that failed, because a shorted igniter or a damaged wire can take out a new part if it isn't addressed.
Once we know what's wrong, we explain the repair and the parts involved before doing the work. If a part needs to be ordered, we tell you so you can plan around it.
Gas, Dual-Fuel and Induction Ranges
Many Sunnyvale kitchens have pro-style gas or dual-fuel ranges, and each type has its own weak points. Gas cooktops tend to develop igniter and burner problems, especially after spills or cleaning that leaves moisture in the spark area. Dual-fuel ranges combine a gas cooktop with an electric oven, so a repair can involve both gas and electrical components.
If you smell gas, turn off the range, avoid using switches near the appliance, open windows and contact your gas utility before scheduling a repair. Gas safety comes first.

Repair or Replace?
A well-built range is usually worth repairing. Igniters, elements, sensors, gaskets and fans are replaceable parts, and fixing them is often far less disruptive than replacing a range that may be fitted to custom cabinetry or paired with a matching hood.
There are cases where replacement deserves a look, such as when a control board for an older model is no longer available or when several major components have failed at once. If we see that situation, we'll tell you plainly and let you decide.
Serving Sunnyvale and Nearby Communities
We work throughout Sunnyvale, from neighborhoods near the Bay to homes closer to Cupertino. Summers in the Santa Clara Valley are dry and can run hot, so a working range and oven matter when you'd rather not fire up an outdoor grill.
Besides Sunnyvale, we also repair ranges in Mountain View, Santa Clara, Los Altos, Cupertino and Los Altos Hills.
