Cooktops take the brunt of daily cooking - spills, grease splatters, and repeated thermal cycling. On gas, electric, and induction cooktops, a maintenance visit keeps burners performing correctly, extends the life of igniters and elements, and checks that the gas fittings are safe.
Gas cooktops: We pull the burner caps and grates, check every port for flow, test spark igniter function on all burners, verify flame pattern and color (should be blue with minimal yellow), inspect the gas supply manifold connections, and check the connection points for gas leaks.
Electric coil cooktops: We inspect heating elements for cracks or burn spots, test element resistance, check coil terminal connections for corrosion, and verify drip pan condition. We also test infinite switch function - the control knobs that regulate temperature.
Electric smooth-top / ceramic glass: We inspect the glass surface for cracks (micro-cracks compromise safety), test all radiant elements, check limiter thermostat function, and verify the glass is sealed to the cooktop frame so spills cannot get underneath.
Induction cooktops: We test all induction zones for consistent heating, verify ventilation isn't blocked (induction units generate internal heat), and check the control board for error codes. Induction needs less upkeep, but an annual diagnostic catches control board issues early.
In many San Francisco homes the cooktop gets heavy use every day. Professional-grade Thermador, Wolf, and Viking cooktops with sealed burners require different care than standard residential units - burner cups are integrated into the cooktop surface, which limits how much you can clean yourself. Our technicians know what those units need.
In coastal properties (Sausalito, Tiburon, Pacifica, Montara), salt air accelerates corrosion of burner grates and igniter electrodes. Give chrome and cast iron grates a periodic wipe with a thin layer of cooking oil after cleaning to prevent rust.
Wipe up spills while they are still wet - sugary liquids harden on burner caps and glass, and hardened sugar damages both. Clean gas burner caps monthly by soaking and scrubbing. For smooth glass tops, use a dedicated ceramic cooktop cleaner (not general-purpose cleaners, which can cloud the surface). On gas units, check that burner caps are correctly seated after every cleaning - an off-center cap causes poor flame pattern and clicking.
We service gas, electric, and induction cooktops across San Francisco, Daly City, South San Francisco, San Bruno, Millbrae, Pacifica, San Rafael, Mill Valley, Sausalito, and Novato. Call (760) 543-5733 or book a cooktop maintenance visit.
Cooktop maintenance from FixitBay LLC covers the burners, igniters and controls, whether the unit is gas, electric or induction, across San Francisco, the Peninsula and Marin. A visit starts from $195, and we are a licensed California appliance technician (BHGS #51001). The $80 diagnostic ($100 commercial) is credited toward the total, so the assessment is not a separate bill. If a burner or igniter needs replacing, the part is covered by a 180-day warranty on parts and labor. Book same-day or next-day; the calendar shows the earliest open window.
A cooktop maintenance visit starts from $195, and the $80 diagnostic ($100 commercial) comes off the total once you approve the written estimate. We do not quote exact prices before we see the unit - what moves the number is which checks your cooktop needs and what the technician finds under the surface. An igniter that has already fouled and failed needs a part, and a hairline crack in a glass-ceramic top means a surface replacement, since we replace a cracked surface and cannot repair it. On sealed-burner professional cooktops the burner cups sit in the surface itself, so the technician has less access than on a standard residential unit. You approve the written estimate before any of that work starts, and parts and labor carry a 180-day warranty.
Once a year is right for most cooktops, with a little extra attention for gas. Clean the surface after each use, and once a month pull the burner caps and grates to soak and scrub the ports - clogged ports are what cause yellow flames and uneven heat. Check that flames burn steady blue. In coastal homes - Sausalito, Tiburon, Pacifica, Montara - salt air corrodes burner grates and igniter electrodes faster, so a light wipe of cooking oil on cast-iron grates after cleaning helps hold off rust. Sealed-burner professional cooktops from Thermador, Wolf, and Viking limit how much you can clean yourself and benefit from yearly professional service. For induction, keep the underside vents clear of dust.
A visit runs 45 to 60 minutes and covers 6 things. We pull the burner caps and check every port for flow, because grease and food debris in the ports turn a flame yellow and create hot spots, and left long enough they damage the igniter, a from-$265 replacement. We test the igniter on every burner and align the electrode, which is usually all a burner that clicks without lighting needs. On gas models we check the supply line and the shut-off valve for micro-leaks with a soapy water test or an electronic detector. We inspect glass-ceramic surfaces for micro-cracks, since a hairline crack is an electrical hazard that ends in a from-$600 surface swap. On induction we test each zone and confirm the underside vents are clear, because these units build heat internally. Then we check the control knobs and switches, where a loose knob points to a worn valve stem. You get a written report of what we found.
Watch for: burner flames that burn yellow instead of blue, a burner that clicks but won't light, a zone that takes too long to heat, new scratches on the glass, or control knobs that feel loose. Most of these trace back to clogged burner ports, a dirty or misaligned igniter, or a worn valve stem - all routine maintenance items. A visit clears them cheaply; ignored, a fouled igniter fails at a from-$265 replacement, and a hairline crack in a glass-ceramic top is an electrical hazard that ends in a from-$600 surface swap. Gas is different - if you smell it, switch nothing on, ventilate, leave, and call PG&E at 1-800-743-5000. If the cooktop is already dead, book a repair; we diagnose it the same way and the $80 still applies.
A cracked glass or ceramic surface has to be replaced, not repaired - a crack is both an electrical and a cut hazard. We assess the damage, quote the replacement, and can source and fit new glass for most brands and models, from $600 depending on the unit.
Yes. We service gas, electric coil, radiant glass, and induction cooktops from all major brands including Bosch, GE, Frigidaire, Samsung, LG, KitchenAid, Thermador, and Wolf. Two configurations benefit from a yearly professional visit. On sealed-burner professional cooktops the burner cups sit in the surface itself, which limits how far you can clean them yourself. Induction asks little day to day, though an annual diagnostic catches control board error codes early and confirms the ventilation underneath is clear. On gas models we also run a supply line and shut-off valve safety check with a soapy water test or an electronic detector. If something has to be replaced, common parts arrive in 2 to 4 business days and specialty components take longer. We quote the lead time before you approve the work. Parts and labor carry a 180-day warranty.
Sometimes, and the technician tells you before doing anything. Anything worth replacing goes on a written estimate at the visit, with the price and, if a part has to be ordered, the lead time, and you approve it first. Common parts arrive in 2 to 4 business days and specialty components take longer, so a repair that needs one is scheduled as a return visit, and that visit carries no second diagnostic fee. Whatever we fit is covered by the 180-day warranty on parts and labor.
It can, so check first. FixitBay LLC is an independent, state-licensed appliance technician (BHGS #51001), not a manufacturer service center, and some manufacturer warranties limit coverage when an independent shop services the appliance while that warranty is still running. If your appliance is still inside its manufacturer warranty, read the terms or call the manufacturer before you book. Once that warranty has expired, our own 180-day warranty on parts and labor is what stands behind the work.
