01, About This Service
A commercial stove burner that won't light at morning prep stops your kitchen before service begins.
A commercial range with a dead burner section during service means reduced cooking capacity, slower ticket times, and a kitchen that's working around its own equipment. We dispatch commercial stove and range calls same day because a burner failure at 10am can become a dinner service problem by 5pm if it's not addressed.
Commercial stoves and ranges, the open-burner cooking surface, have distinct failure modes from commercial ovens. This page covers stove surface repairs: igniters, gas valves, thermocouples, burner orifice cleaning, spark modules, and open burner assemblies. For oven section repairs (convection ovens, deck ovens, the enclosed oven cavity below the range top), see our Commercial Oven Repair page.
Southern California has one of the most diverse commercial kitchen landscapes in the US, from the high-BTU wok ranges running 150,000–200,000 BTU/burner in LA's Chinatown and Koreatown, the San Gabriel Valley Chinese restaurants, OC's Anaheim and Garden Grove Korean/Vietnamese corridors, and the IE's growing Asian foodservice clusters; to the charbroilers in Beverly Hills, Newport Beach, and Westlake Village steakhouses; to the standard 6-burner Vulcan or Garland ranges in every independent restaurant on the East Hollywood corridor and across all five counties. We repair all of these, and we come prepared for high-BTU burner work. Same-day priority dispatch, BHGS Licensed #A49573.
If you smell gas near your commercial stove: call your gas utility, SoCalGas at 1-800-427-2200 across most of LA, OC, Ventura, and parts of SB; Southwest Gas at 1-877-860-6020 for Riverside, Anaheim, Long Beach, and parts of SB. They respond quickly, shut off gas safely, and confirm the area is clear, at no charge. Once the gas is secured, call us at for the mechanical repair. Gas utility first, appliance repair second.

Commercial Oven Repair Los Angeles →03, Commercial Range Types We Service
Every commercial cooking surface configuration in SoCal kitchens
Standard Gas Ranges (6–10 Burner)
The most common commercial range in SoCal independent restaurants. Vulcan V-series, Garland G-series, Southbend, typically 30,000–35,000 BTU per burner. Igniter, gas valve, thermocouple, orifice.
High-BTU Wok Ranges
75,000–200,000 BTU per burner for wok cooking. Chinese, Korean, Vietnamese restaurants in LA's Chinatown, Koreatown, San Gabriel Valley; OC's Anaheim/Garden Grove corridor; IE's growing Asian foodservice clusters. Larger orifice, higher-capacity gas valves, different repair approach from standard ranges.
Griddles & Flat Tops
Gas flat-top griddles for breakfast service, burger operations, and short-order cooking. Thermostat, gas valve, igniter, plus surface cleaning and re-seasoning guidance.
Charbroilers
Gas charbroilers for steakhouses, burger restaurants, and specialty grills. Radiants, burner assemblies, gas valve, igniter. Beverly Hills, Newport Beach, and Westlake Village fine dining and casual restaurant charbroiler service.
Combination Ranges
Full commercial range with burner section above and oven section below. We repair both sections, burner surface and oven chamber, on the same visit when needed.
Commercial Induction Ranges
Commercial induction cooktops for SoCal kitchens electrifying their cooking suites, increasingly common in new restaurant buildouts across LA, OC, Ventura, and IE. Control board, induction coil, cooling fan.
LA Koreatown / Chinatown / SGV + OC Anaheim/Garden Grove + IE Asian foodservice clusters, the wok range capital of the western US
Southern California has the largest concentration of Chinese, Korean, and Vietnamese restaurants outside of Asia, and these cuisines demand high-BTU wok burners that standard commercial range repair technicians often haven't worked on. A wok range running 150,000 BTU per burner requires larger orifice jets, higher-capacity gas supply lines, and different igniter assemblies than a standard 35,000 BTU burner.
Common failure modes on high-BTU wok ranges: clogged wok ring orifice jets from carbon buildup (high-BTU burners produce more carbon than standard burners), failed high-capacity gas valve, igniter failure from the intense heat environment. We carry appropriate parts and tools for high-BTU burner repair across all five SoCal counties. When you call, mention "wok range" and we'll confirm the right tech and parts for your visit.
04, Common Failures
What our technicians diagnose most often in SoCal commercial stoves
Burner Won't Light
Three causes in order of frequency: (1) failed igniter or spark module, no spark visible when attempting ignition; (2) clogged burner orifice, spark present but gas can't flow; (3) failed gas valve, gas not reaching the burner. Try removing the burner cap and grate and cleaning debris first. If the orifice hole appears blocked, a cleaning service may resolve it without parts replacement.
Weak or Yellow Flame
A properly burning gas burner produces a blue flame with a defined cone. Yellow or orange flame indicates incomplete combustion, most commonly from a clogged or partially blocked burner orifice, or a burner cap misaligned after cleaning. A weak flame regardless of color suggests insufficient gas pressure reaching the burner, pointing to a partially failed gas valve.
Pilot Light Won't Stay Lit
Standing pilot systems on older commercial ranges use a thermocouple, a temperature sensor that detects the pilot flame and allows the main gas valve to stay open. When the thermocouple fails, the pilot lights but the main gas valve closes and the burner won't stay on. Thermocouple replacement is a $80–$150 repair. Don't bypass or tape the thermocouple, it's a safety device.
Burner Ignites Then Goes Out
On electronic ignition systems, this usually indicates the flame sensor (sometimes called a thermocouple or flame rod depending on the system) isn't detecting the flame and cutting off the gas valve. The flame starts, the valve opens, then closes when the sensor doesn't confirm sustained combustion. Sensor cleaning or replacement resolves this in most cases.
Uneven Heat / One Section Not Working
On a multi-section range (6-burner, 8-burner), one side or section not lighting while others work normally usually indicates a zone gas valve failure rather than individual burner issues. Zone valves control multiple burners; when a zone valve fails, all burners in that zone go down together. Useful diagnostic: if all three left burners fail simultaneously, it's likely a zone valve, not three separate igniter failures.
Griddle Temperature Inconsistent
Commercial griddle thermostat drift, the thermostat controls griddle surface temperature and wears out over time. A griddle showing 350°F but cooking inconsistently at 300°F or 420°F has a drifted or failing thermostat. We calibrate against a calibrated probe before condemning the thermostat, since sometimes the display is inaccurate rather than the heating system itself.
05, Gas Safety Protocol
Gas smell at your commercial stove, the right sequence
This is the correct order of operations. Most operators don't know that the gas utility responds faster and at no charge.
Turn off the stove and move staff away. Don't operate electrical switches that could create a spark.
Call your gas utility: SoCalGas 1-800-427-2200 (LA, OC, Ventura, parts of SB) or Southwest Gas 1-877-860-6020 (Riverside, Anaheim, Long Beach, parts of SB). They respond quickly, shut off gas supply safely, and verify the source, at no charge to you.
Ventilate the space, open kitchen doors and windows once you're sure there's no ignition source.
Call us at once gas is secured. We diagnose the failed component and repair same day.

07, Recent Repairs
What our technicians actually fixed recently
"Two wok burners won't light, carbon buildup, orifice completely blocked"
Clogged wok ring orifice jets on two of three burners of an American Range wok range running 150,000 BTU per burner. The orifice jets on high-BTU wok burners accumulate carbon at a much faster rate than standard commercial burners, the intense heat conditions and wok cooking technique (sauce and oil splashing directly into the flame) builds carbon deposits in the jet orifice over months.
"Left side three burners completely dead, right side works fine"
Zone gas valve failure on a Garland 6-burner range at a Newport Beach steakhouse, the valve controlling the left-side burner zone had failed closed, cutting off gas to all three left burners simultaneously. Classic zone valve failure presentation: three burners go down at the same time rather than one. The restaurant had been running dinner service using only the right three burners, slowing their line and affecting ticket times.
"One burner ignites but goes out after 5 seconds"
Failed flame sensor on a Vulcan V6B electronic ignition range at a Westlake Village bistro, the flame rod (a probe that detects the presence of flame and holds the gas valve open) had corroded and was no longer producing adequate ionization current to signal the control board. The burner would ignite, the control board would check for flame confirmation, fail to detect it, and cut the gas valve, all within a few seconds.
"Pilot light keeps going out, burners won't stay lit"
Failed thermocouple on a standing-pilot Imperial range, the thermocouple generates a small millivolt signal when heated by the pilot flame, which holds the main gas safety valve open. When the thermocouple fails, the valve defaults closed (the safe state), and no burners will ignite or stay on. The restaurant had been relighting the pilot every 30–45 minutes until it stopped staying lit at all.

09, Frequently Asked Questions
Commercial stove repair, what SoCal operators ask us
How much does commercial stove repair cost?
Commercial diagnostic is $120, applied to repair if approved. Most repairs run $150–$500. Igniter, thermocouple, gas valve, orifice cleaning, or flame sensor is in this range. Zone valve work runs higher. Written estimate before any work begins.
Which areas of Southern California do you cover for commercial stove repair?
Same-day across Los Angeles, Orange, Ventura, San Bernardino, and Riverside counties, Koreatown and Chinatown LA wok ranges, San Gabriel Valley Chinese restaurants, Anaheim and Garden Grove OC Korean/Vietnamese kitchens, Thousand Oaks Conejo Valley restaurants, Rancho Cucamonga and Riverside IE foodservice. Eight service territories total. Vulcan, Garland, Southbend, Imperial, gas-certified across the entire footprint. BHGS Licensed #A49573.
My commercial gas stove smells like gas, what do I do?
Call your gas utility first, SoCalGas at 1-800-427-2200 across most of LA, OC, Ventura, and parts of SB; Southwest Gas at 1-877-860-6020 for Riverside, Anaheim, Long Beach, and parts of SB. They'll shut off gas safely at no charge and confirm the area is clear. Then call us at for the mechanical repair. Gas utility first, appliance repair second.
My commercial burner won't light, what should I check first?
Remove the burner cap and grate and check for debris or carbon buildup in the burner orifice hole. A clogged orifice is the most common cause and cleans up in minutes. If the orifice is clear and there's no spark, that's an igniter. If there's a spark but no flame, that's a gas valve or clogged orifice.
Do you repair wok ranges and high-BTU commercial ranges?
Yes. High-BTU wok ranges (75,000–200,000 BTU/burner) are a significant part of our SoCal service calls, LA's Chinatown/Koreatown/SGV, OC's Anaheim/Garden Grove, IE's Asian foodservice clusters. When you call, mention "wok range" so we bring the appropriate parts and tools.
What's the difference between commercial stove and oven repair?
Stove repair covers the open-burner cooking surface, igniters, gas valves, thermocouples, orifices. Oven repair covers the enclosed cooking chamber, heating elements, convection fans, deck oven systems. Most commercial ranges have both; we repair both on the same visit when needed. See our Commercial Oven Repair page for oven-specific issues.
Do you repair Vulcan, Garland, and Southbend commercial ranges?
Yes. Vulcan, Garland, Southbend, Imperial, and Montague are our most common SoCal service brands. Parts for Vulcan and Garland carried on service vehicles; others sourced same-day.
When does it make sense to repair vs replace a commercial range?
Commercial ranges last 12–20+ years with proper maintenance. Repair almost always wins. New 6-burner Vulcan or Garland ranges run $4,000–$9,000+; high-BTU wok ranges $6,000–$15,000+; charbroilers $3,000–$7,000. A $400–$700 zone valve replacement on a $7,000 range with another decade of life is straightforward math. We tell you directly when a unit has reached end-of-life, usually only after a full burner-bank gas-valve assembly fails on a unit already 20+ years old.
