The short answer
Gleadale Appliance services repairs gas, electric and induction cooktops in South Pasadena, including Wolf, Viking and Thermador models. Most problems come down to a specific part, such as an igniter, spark module, burner valve, control board or cooling fan, and we diagnose the cause before recommending any repair.
When a burner won't light, the igniter keeps clicking after the flame catches, or an induction zone shows an error code mid-dinner, cooking gets awkward fast. Gleadale Appliance services repairs gas, electric and induction cooktops in South Pasadena homes throughout ZIP code 91030. We're based in Glendale, about 6 miles west, so South Pasadena is a short drive for us. Our work centers on premium kitchens, where a Sub-Zero refrigerator often sits alongside a Viking, Wolf or Thermador cooktop, and we repair all four brands. We are an independent repair company, not affiliated with or endorsed by any manufacturer. On this page you'll find the problems we see most often, a few checks you can do safely yourself, and what to expect when a technician comes out.
Gas cooktop problems we repair
Most gas cooktop calls involve ignition or flame quality. A burner that clicks but won't light usually has a dirty or cracked igniter, a burner cap that isn't seated correctly, or a clogged port. If every burner clicks at the same time and won't stop, the cause is often moisture from a spill or a failing spark module. Premium cooktops add their own details, such as Wolf's dual-stacked burners and Thermador's star-shaped burners. Both rely on precise cap and port alignment, so a flame that looks fine at high heat may go out on the lowest setting.
We check the full path from the control knob to the flame before replacing anything, so you aren't paying for parts that don't fix the problem.
- Burner clicks but won't ignite
- Constant clicking after the burner is lit or turned off
- Weak, yellow, uneven or lifting flames
- Simmer setting goes out or won't hold low heat
- Stiff, loose or broken control knobs and valves
- Igniter sparks on the wrong burner
Induction and electric cooktop repair
Induction cooktops depend on electronics, so the symptoms look different. A zone may not detect the pan, shut off after a few minutes, buzz louder than usual, or display a fault code. Common causes include a failing cooling fan, an overheated or damaged power board, a bad touch control, or cookware that isn't magnetic enough to register. We read the fault codes, test the boards and fan, and tell you which part has failed.
On electric radiant cooktops, we often find an element that won't heat, one that only runs at full power, or a hot-surface light that stays on. These usually point to the element, its switch or the wiring. We also check cracked glass-ceramic tops. A crack is a safety issue, and the burner under it should not be used until the top is replaced.
Before you call: safe checks you can do
A few simple checks can save you a service visit. Only do the ones you're comfortable with, and keep the cooktop off and cool while you work.
- Make sure burner caps and grates sit flat and centered on their bases
- Let a wet burner dry fully after a boil-over, then try it again
- Look for a tripped breaker or a GFCI outlet that needs resetting
- For induction, test the zone with a pan a magnet sticks to firmly
- Write down any error code exactly as it appears
- If you smell gas, don't use any switches or flames. Leave the house and call your gas utility from outside.

How a cooktop repair visit works in South Pasadena
When you contact us, tell us the brand, the model number if you can find it, and what the cooktop is doing. The model plate is usually under the cooktop or on the side of the chassis, and some models show it inside the cabinet below. That information helps us arrive prepared for your specific Viking, Wolf or Thermador model.
At your home, the technician diagnoses the problem, explains what failed, and gives you the repair options before starting any work. Cooktops are built into the counter, so we take care to protect your countertop and cabinets when we lift the unit or reach underneath. If a part has to be ordered, we tell you so up front and schedule a return visit. Besides South Pasadena, we also serve nearby Alhambra, San Marino, San Gabriel, Pasadena and Monterey Park.
Repair or replace?
High-end cooktops are built to be serviced, and fixing one is often more practical than replacing it, especially when the opening is cut to fit a specific model. Igniters, spark modules, valves, fans and many control boards can be replaced individually. If a repair doesn't make sense, for example because parts for an older model are no longer available, we'll tell you plainly so you can make the call.
