Common Commercial Oven Problems
When a commercial oven quits, the kitchen it anchors quits with it: no bakes, no pizzas, no banquet covers going out. FixitBay LLC repairs commercial ovens of every type across San Francisco, the Peninsula, and Marin County.
Our licensed technician diagnoses convection, deck, pizza, combi, and conveyor ovens plus commercial ranges on site: thermostats and temperature controls, gas burners and igniters, heating elements, and convection fan motors. The $100 diagnostic fee is credited toward your repair, and you approve a written flat-rate quote before we start.
From a Rational combi with a failed steam generator to a Bakers Pride deck that won't hold temperature, we repair the whole range of commercial cooking equipment. Every job includes our 180-day warranty on parts and labor.
Convection Oven Not Heating Evenly
Convection fan motor failures, element burnout, or baffle damage causing hot spots and cold zones in commercial convection ovens. Critical for bakeries and restaurants that depend on consistent baking results.
Pizza Oven Temperature Issues
Deck pizza ovens not reaching or maintaining target temperature (typically 500-700°F). Gas burner clogs, thermostat drift, or insulation degradation affecting pizza quality in San Francisco pizzerias.
Combi Oven Steam Generator Problems
Steam generator scale buildup, heating element failure, or water supply issues in combi ovens. Scale from San Francisco's mineral-rich water is the failure we see most on combi ovens here.
Gas Burner Ignition Failures
Commercial gas ovens and ranges failing to ignite. Pilot light going out, electronic igniters cracking, or gas valve solenoids failing in high-use restaurant environments.
Digital Control Panel Errors
Modern commercial ovens displaying error codes, touchscreen becoming unresponsive, or programmed cooking profiles lost due to control board failures or power surge damage.
Door Seal and Hinge Failures
Oven door gaskets degrading from thousands of heating cycles, allowing heat loss. Broken hinges, worn springs, or latch failures on commercial ovens and ranges requiring heavy-duty replacements.
Range Hood and Exhaust Issues
Kitchen range hoods with failed fan motors, worn belts, or grease-clogged filters reducing ventilation. Proper exhaust is required by San Francisco fire code for all commercial cooking equipment.
Conveyor Oven Belt Problems
Conveyor ovens with belt tracking issues, belt tears, or speed control failures affecting cook time and food quality in high-volume restaurant and catering operations.
What Commercial Ovens Do We Repair?
A neighborhood pizzeria, a bakery, a hotel banquet kitchen, and a taqueria all cook on different equipment and break it in different ways. We service every oven type on this page and bring the right test gear and parts for the one you run.
Convection Ovens
Full-size and half-size convection ovens from Blodgett, Vulcan, and Garland. Fan-forced hot air circulation for even baking. Common issues: fan motor bearings, heating elements, thermostat calibration, and door gaskets. Used in nearly every San Francisco restaurant kitchen.
Pizza Ovens (Deck)
Gas and electric deck ovens from Bakers Pride, Blodgett, and Marsal. Stone or steel decks that reach 500-700°F for artisan-style pizza. Common issues: burner clogs, thermostat drift, cracked decks, and insulation degradation.
Combi Ovens
Combined steam and convection ovens from Rational, Alto-Shaam, and Electrolux Professional. The most versatile and complex commercial oven type. Common issues: steam generator scale buildup (especially with San Francisco water), control board failures, and fan motor problems.
Conveyor Ovens
Belt-driven ovens from Middleby Marshall, Lincoln, and TurboChef for high-volume operations. Common issues: belt tracking, heating element zones, speed controller failures, and conveyor motor problems.
Commercial Ranges
Gas and electric ranges with 4-12 burners plus ovens from Vulcan, Garland, and Wolf. The backbone of every commercial kitchen. Common issues: burner igniters, gas valves, oven thermostats, and range top regulator failures.
Range Hoods & Exhaust
Kitchen ventilation systems including hood fans, make-up air units, and grease filtration. San Francisco fire code requires proper exhaust for all commercial cooking. Common issues: fan motor failure, belt wear, grease filter saturation, and airflow imbalance.
Why Do Combi and Pizza Ovens Need a Specialist?
A Rational combi runs $15,000 to $40,000 and a quality deck oven $5,000 to $20,000, so a repair almost always beats replacement, and it is worth having someone who works on these systems regularly. Our technician is trained on combi and deck ovens specifically.
Combi Oven Steam Generator Descaling & Repair
San Francisco water has moderate mineral content that causes scale buildup in combi oven steam generators over time. Scale reduces heating efficiency, causes temperature inaccuracy, and eventually blocks water flow entirely. We descale steam generators, replace calcified heating elements, repair water treatment systems, and advise on water filtration to prevent recurrence.
Pizza Oven Deck & Temperature Calibration
Artisan pizza requires precise, consistent deck temperatures. We calibrate thermostats using professional infrared thermometers, test temperature recovery time (how quickly the oven returns to set temperature after loading), and repair gas burners, igniters, and insulation to ensure consistent performance for San Francisco pizzerias.
Conveyor Oven Belt & Zone Repair
Conveyor pizza ovens and toasting ovens require precise belt speed and even heat distribution across multiple heating zones. We diagnose zone heating failures, calibrate belt speed controllers, replace worn belts, and repair conveyor motors to restore consistent throughput.
Repair vs. Replacement - Commercial Ovens
Commercial ovens are built heavy-duty. Most repairs are far cheaper than replacement.
Commercial ovens last 15-25 years. Individual component repairs are almost always worthwhile.
Common repairs (from $350) that restore full heating. A fraction of a $5,000+ new oven.
Thermostat replacement or calibration ($375) restores cooking accuracy.
Major structural issues compromise safety. Replacement is the responsible choice.
Our honest policy: If our diagnostic shows the repair isn't economically justified - we'll tell you before any work begins. No pressure, no hidden charges beyond the $100 diagnostic fee.
How We Diagnose and Fix Commercial Ovens
Commercial Diagnostic
We test igniters, gas valves, thermostats, convection motors, safety controls, and door seals. Gas pressure and temperature accuracy are measured with professional instruments.
