JennAir Radiant Cooktop Display Starting With U: Pan, Keep Warm or Power

What Begins with U means

On JennAir electric radiant and touch-control cooktops, a display that begins with the letter U has three possible meanings. U can mean no pan is detected on the cooking area, in which case you should place a suitable utensil on it. U can also show that the Keep Warm function is on. Less often, it can point to a problem with the electrical power supply.

Common causes of Begins with U

No pan on the selected cooking area
The Keep Warm function is turned on
A problem with the electrical power supply to the cooktop

✓ One safe check you can try

1. Check the cooking area. Place a suitable, flat-bottomed utensil on the desired area. 2. Look at the control to see whether Keep Warm is on and switch it off if you do not want it. 3. If U stays with a pan in place and Keep Warm off, turn the cooktop's breaker off for one minute and back on. 4. If U returns, call us.

! Why to stop there

Two of the three meanings are normal operation, so a repair would be wasted.
Power supply checks involve live terminals, which are not safe for owners.
The display letter alone does not tell which meaning applies, so check the pan and Keep Warm first.

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

Why does my cooktop show a U?

It may mean no pan is detected, the Keep Warm function is active, or there is a power supply issue. Check for a pan and for Keep Warm first.

How do I stop the U for Keep Warm?

Turn the Keep Warm function off at the control for that cooking area. The U goes away once Keep Warm is off and the area has no pan.

When should I call you?

Call us if U remains with a suitable pan and Keep Warm off, and a breaker reset does not help. Then the supply or control needs a technician, and you get a written price first.
