KitchenAid Smoothtop Cooktop Display Beginning with U: No Pan or Keep Warm

What Begins with U means

On KitchenAid electric radiant (smoothtop) touch-control cooktops, for example the KCES550HSS or KECC664BSS, a display that begins with the letter U can carry three different meanings. It may say no pan is detected on the cooking area, show that the Keep Warm function is on, or point to a problem with the electrical power supply. Which one applies depends on whether a pan is in place and how the cooktop was set.

Common causes of Begins with U

No pan, or one that is too small, on the selected cooking area
Keep Warm switched on, which is a normal indication
A problem with the electrical power supply reaching the cooktop
A control that loses power intermittently and needs testing

✓ One safe check you can try

1. Check whether a suitable utensil sits centered on the area you selected and swap in a larger one if needed. 2. If you did not mean to use Keep Warm, turn that area off and start over. 3. Reset the cooktop breaker once, wait a minute and watch the display. 4. If U keeps appearing with a pan in place, stop and call us.

! Why to stop there

The power-supply reading cannot be told apart from a wiring or control problem without meter tests at the cooktop.
Those tests involve live circuits, which are not safe for owners.

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.

Begins with UBegins with U questions

What does the letter U mean on my smoothtop cooktop?

It is used for more than one message. The common ones are no pan detected on that area and Keep Warm being active. A third meaning is a power supply problem, so the right answer depends on what you had set.

The U appears even though a pan is on the burner. Why?

The pan may be too small, off center or not the right size for that cooking area. Move it to the middle and try a larger utensil. If U remains, the area or its control needs checking.

Can a breaker reset clear a U message?

Only when the message came from a power supply glitch. Switch the breaker off, wait a moment, switch it back on and watch for a minute. If the U returns, there is likely an actual supply or control issue.
