Bertazzoni MAST365QXE 36-Inch Cooktop Service

A MAST365QXE usually sits in a long run of counter, often as the focal point of a kitchen island or a wall of cabinets. This 36-inch Master Series cooktop has five sealed burners, and the high-output center burner does the hardest work, from boiling to searing.
That center burner is the one that tends to show age first. When flame appears on just part of the ring, grease and carbon are almost always packed into the slots, or the cap is not fully seated. We lift the cap, clean the ring, check the igniter gap and confirm the flame is steady on every setting.
Gas smell means leave the home and call the utility from outside. Our estimate is written before any work, and the repair carries our 30-day workmanship warranty.
Residue in the ring slots blocks gas flow to part of the flame. We clean the slots, reseat the cap and check that the burner head is level, which restores an even ring.
The burners share the same electronic ignition setup, so several clicking at once points toward the module or its power. A single burner usually points to its own igniter or cap.
Let them cool, then wash with warm soapy water and dry fully before replacing. Wet caps can keep a burner from lighting, so dryness matters more than scrubbing hard.
