The E4 error code on a Kenmore induction cooktop means the cooktop cannot detect a compatible cooking vessel on the active zone, or the cookware detected is too small for the zone.
Causes
- Non-magnetic cookware placed on the zone (aluminum, copper, glass, ceramic)
- Cookware too small — induction zones require a minimum pot diameter
- Warped cookware with poor contact to the glass surface
What To Do
- Test your cookware with a magnet — if the magnet sticks to the bottom, the cookware is induction-compatible.
- Use cookware with a flat, stable base of at least 4–5 inches diameter for standard zones.
- If E4 appears with known-compatible cookware, the zone coil or sensor may require professional inspection.
