If your gas cooktop flame went weak or lopsided right after you cleaned the stove, something got disturbed during cleaning or when you put it back together. It is almost always mechanical, not a gas supply problem. This holds true whether you are running a GE, Samsung, Whirlpool, Bosch, or KitchenAid gas cooktop, since they all use the same burner-cap-and-port setup. Here is what is likely going on.
Most likely: blocked ports
Burner ports are the small holes ringing the burner head where the flame comes out. Cleaning can push residue, solution, or water into them, and it dries there. The flame that results looks lazy, orange, or one-sided.
Do the visual check yourself. Lift the burner cap, which just lifts off, shine a flashlight at the ports, and look for blockage. That alone tells you the problem is mechanical. Clearing clogged ports is the part that needs the right tool, though. The wrong implement enlarges the port or breaks off inside it. If you see blockage and are not sure how to clear it cleanly, stop there.
Cap sitting off
The cap sits on the burner head and controls how gas spreads around the ring. Most cooktops use alignment pins or marks, and a cap seated even slightly off gives you a weak or lopsided flame.
This one is worth checking before you call anyone. Lift the cap straight off, wipe the underside, and reseat it flat, lining up the pins or marks. Fire the burner and watch the ring. Even and blue all around means you are done. If not, something else is going on.
Moisture from cleaning
If you soaked the grates and caps in the sink, water can sit in the igniter electrode or in the recesses of the burner head. A wet igniter clicks constantly or sparks weakly. A wet head starts the flame low and uneven until it dries. If you reassembled while things were still damp, let the cooktop rest fully dry and retry. Two to four hours beats one. If moisture was the whole story, it clears on its own.
Past the easy checks
Reseated the caps, let everything dry, still weak? The cause is likely past what you can see without disassembly. A partly blocked gas orifice, the small brass fitting that meters gas into the burner, is the common next culprit after a cleaning. It is easy to damage and not something to poke at with improvised tools. Debris in the venturi tube, a burner head damaged by cleaning chemicals, or a valve problem are the other options. All of them mean working around gas, and that is where a tech takes over.
How we sort it
First question: did the trouble start right after cleaning? That narrows it fast. Pull each cap, check the ports with a light, fire each burner, and read the pattern. A short or uneven flame on one side points to a port or cap. A uniformly low flame with the valve wide open points to the venturi or orifice. If every burner went weak at once, that is a regulator or supply issue, a different conversation. One burner acting up after cleaning is almost always local and mechanical.

You have probably already done the visible checks, and that helps, it tells the tech where to start. If the flame is still off after reseating the cap and drying everything out, there is no safe next step without proper tools and disassembly.
