Upon inspection, the cooktop was exhibiting a persistent clicking sound, which is often indicative of an issue with the burner heads. I began by carefully disassembling the cooktop to access the burner heads. Each burner head was meticulously cleaned to remove any debris, buildup, or residue that might have been causing the malfunction. Using specialized tools and cleaning agents, I ensured that every component was thoroughly cleaned. After reassembling the cooktop, I tested each burner to confirm that the clicking sound had ceased and that the cooktop was functioning correctly. The customer was pleased with the resolution and the cooktop's restored performance.
