A rangetop’s higher-output burners are built for serious daily cooking, which also means grease and boil-over residue accumulate faster than on a standard cooktop.
Burner Caps and Ports
Food debris and boil-over residue that dry into the small ignition ports around a burner cap are the leading cause of uneven flame and ignition delay. A soft brush and warm soapy water, done regularly, prevents most of this.
Grates
Cast-iron or porcelain grates that sit slightly uneven from repeated heavy-pot use can cause a pan to rock during cooking. Checking grate seating periodically catches this before it becomes a stability or performance complaint.
Griddle Care (If Equipped)
A rangetop griddle surface should be seasoned and cleaned per the manufacturer’s guidance rather than treated like a standard burner grate — using the wrong cleaning approach here is a common source of surface damage we see.
When Cleaning Isn’t Enough
If a burner still won’t light evenly after a thorough cleaning, the igniter or spark module itself is likely worn, which our Monogram rangetop repair technicians can confirm and replace in a single visit.
