Keep Monogram rangetop burners lighting evenly with regular cleaning of caps and ports, a check of grate seating, and the right care for a griddle.

A rangetop like the ZGU364NDP-SS is cooktop-only — no oven cavity underneath — so its problems are purely burner and ignition-side issues: igniters, burner ports, and the gas valve assembly, without any oven electronics to complicate diagnosis.
