Electric cooktop element does not heat or only heats partially.

Safety first: Turn off power at the breaker before lifting the cooktop or accessing elements. Electric elements operate at high voltage.

Steps to check and correct:

• Visual check: For radiant elements under glass, look for visible breaks or hot spots. For coil elements, inspect for breaks or burn marks.
• Swap elements (coil type): Swap the suspect coil with a known good one. If the problem follows the element, replace it.
• Test continuity: With power off, test the element for continuity. Replace if open.
• Check switch: If the element is good, the infinite switch or control for that burner may be faulty and require replacement.

When to call a technician: For glass-top ranges where elements and limiters are integrated, or if control boards are involved, professional service is recommended.
