What to Check First
- Cookware not suitable for an induction range was used.
- Cookware that does not match the burner size was used.
- The overheating prevention system was activated so the induction stopped working.
- The highlight stopped operating to maintain the temperature of the cooktop.
- Is your induction or highlight burner too weak? Did your burner stop operating while cooking?
- ➔ Use induction-compatible cookware.
- If induction-compatible cookware is not used, [U] will be displayed and the burner will not operate properly. Use induction-compatible cookware with an IH or coil symbol at the bottom or an appropriate cookware according to the following information. If cookware that worked fine before is not heating, check to see if it may be cracked or if there are foreign objects on its bottom surface. If you purchased new cookware, it is better to first check if it works before cooking.
- How to check your cookware for induction compatibility.
- ① Cookware with an IH symbol ※ If the bottom of the cookware is not magnetic, it cannot be used even if it has an IH symbol. ② Cast iron frying pan/pot ③ Porcelain enamel pot.
- ① Aluminum/tin pots ② Nickel-silver pots ③ Heat-resistant glass pots ④ Grill pots ⑤ Stone pots, porcelain pots, earthen pots ※ Porcelain pots may be broken or their heating power will be weak so cooking may not be possible, even if these pots have an IH symbol.
