JennAir Induction Cooktop Symbol U u: Pot Not Detected or Not Suitable

What U u means

On JennAir induction cooktops such as the JIC4536KS, the symbol U u appears when the pot is not suitable for induction cooking, is not positioned correctly or is not the right size for the cooking zone selected. If no pot is detected within 30 seconds of making the selection, the cooking zone switches off. It is a prompt, not a breakdown.

Common causes of U u

A pot made from material that does not work with induction
A pot placed off-center or on the wrong zone
A pot too small for the selected zone

✓ One safe check you can try

1. Turn the zone off. 2. Place a pot made for induction cooking on the zone you want. 3. Center it over the marked circle. 4. Pick the zone and power level again within 30 seconds. 5. If U u shows with a suitable pot, call us.

! Why to stop there

The cooktop is working as designed, and a visit would not change that.
Moving the pan is quick and free.
Only a suitable, centered pan that is not detected needs a technician.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

U uU u questions

Why does the zone switch off after 30 seconds?

If no suitable pot is detected within 30 seconds of making the selection, the cooking zone turns itself off. That protects the cooktop and saves energy.

What pots work?

Pots made from ferromagnetic material, such as cast iron, enameled steel or stainless steel designed for induction. Center the pot on the zone you picked.

When is U u a repair problem?

It becomes a repair problem when a suitable, centered pot is still not detected. Then the detection circuit may need checking, and we quote in writing before any work starts.
