CooktopGE Profile PGB910SET2SS, five sealed burners
Billabout $235
The owners had already swapped the burner heads
Before booking, the owners wrote that the back burner made a strong clicking sound but would not light, while every other burner worked. They had cleaned the burner head, tried the other heads in its place, and found it lit fine with a barbecue fire starter. They asked whether the electrode needed adjusting.
It did. The technician adjusted the electrode on the left rear burner and cleaned the burner. No part was needed.

CooktopNXR LS3055 pro-style gas range, four burners
Billabout $235
A burner that wouldn’t stop sparking after it lit
On this NXR, the left rear burner lit and went on sparking. The cause was a damaged igniter wire on that burner. The technician repaired the wire; the notes list no new part.
The range’s plate lists two 15,000 BTU front burners and two 9,000 BTU rear burners, so the faulty one was a 9,000.

Billabout $420
Clicking on its own, and already unplugged by the gas company
This Samsung was clicking with nobody using it. The gas company came out first, looked it over and pulled the plug for safety, and then the owners booked us.
The technician worked through the ignition system. We replaced the spark module assembly and the ignition switch assembly, the parts that make the spark and tell the module when to fire.

A $1,000-plus repair we told them not to do
The left rear burner wouldn’t spark. Its spark switch had failed, and reaching it meant taking the cooktop cover off.
Opening it up showed more. On the two front burners the mounting nuts had seized, so they would have to be cut off and replaced with new hardware. The burner venturi set looked seized too, and original venturis are no longer available, only aftermarket ones. The technician put the whole job above $1,000 and recommended replacing the cooktop instead. No parts went in; the owners paid only the $85 diagnostic.

The owner reported the stovetop flame dropping to low mid-cook. The technician went to the gas line feeding the range: pressure there tested too low. The fault was in the supply, not a part we could replace on the range.

A vintage range with standing pilots and a gas smell
The owner smelled gas “not from the valve but from inside.” The technician checked the range for leaks and found none, then adjusted the top-burner pilot lights and relit the oven pilot.
Electric glass tops and induction
No flame to check: elements, switches and the glass.

One zone dead: the element and the switch behind it
The owner booked for a leaking freezer and mentioned that one burner on the glass-top stove didn’t work. On the range, the left front surface element had failed along with its control switch. We replaced both.
The invoice covered the refrigerator work too, so we can’t give a cooktop-only price for this one.

Bill$85 diagnostic only
Shattered glass, and a part that takes a search
The owners were leaving town the next day and wanted an estimate first, in case parts had to be ordered. The glass over one zone had shattered, leaving a hole.
The label underneath says Chef Australia made the cooktop for Regency V.S.A. The replacement top glass assembly is not a stock part for this brand; it needs a special part search. So this one closed as an estimate only, billed at the $85 diagnostic.

November 2026 · Chatsworth (91311) · induction range · $85
An induction cooktop with nothing wrong
Booked as “induction stove doesn’t work.” On the day, every test came back clean: the technician’s note reads that nothing mechanical was wrong, so the owners paid the diagnostic and nothing more.

When the visit ends at $85
Los Feliz, Los Angeles 90039, the Regency in Santa Monica and Chatsworth all stopped at the diagnostic: a repair not worth doing, a gas-supply problem, a part that needs a search, and no fault. The $85 is credited when you go ahead with a repair.
What the bills above tell you
No “typical cooktop price” here, on purpose.
Our records file cooktops together with ovens and ranges, and once the leveling calls and mixed oven-and-cooktop tickets are taken out, too few clean cooktop invoices are left for a median to mean anything. So read the real bills in the stories instead: $85 where we stopped after diagnosing, about $235 for an electrode adjustment or an igniter-wire repair, about $420 for a new spark module and ignition switch. Our other oven and range repairs have a median of about $400, and every appliance we fix together, about $365. More on visit costs: pricing. Ovens and full ranges: oven and range repair.
