What F3 (721 Elite double oven) means
On Kenmore Elite double-oven ranges numbered 721., an LG-built platform, F3 means a stuck key, shown on the oven or cooktop display that has the problem. The control thinks a button is being pressed continuously and may therefore ignore other presses or lock itself out. This is a control input message, not an oven heating or sensor code, and the other oven and cooktop may behave normally.
Common causes of F3 (721 Elite double oven)
- A key held in or sticky from a spill
- Ribbon or keypad connection
- The keypad itself
- The control reading the key
1. Look at the affected panel for a button that is stuck in or soiled. 2. Wipe the panel gently with a barely damp cloth and dry it. 3. Press each key once to free it. 4. Flip the range breaker off for a minute, then on again. 5. If F3 returns, call us.
- A stuck-key code can be a dirty key or a failing keypad
- We check the keypad and ribbon wire
- We quote in writing first and replace only what tests bad

Does F3 mean the oven is broken?
Not usually. On this 721 platform it reports a stuck key on one display. The heating parts are normally unaffected, but the control may not accept commands.
Which display shows it?
It appears on whichever panel, oven or cooktop, has the stuck key. That tells us where to look, so note which display shows F3 when you call and whether other keys still respond.
Will you replace the keypad right away?
Only if it tests bad. We check for a soiled key or a loose ribbon first, give a written price before work, and cover our workmanship for 30 days.
Still unsure about F3 (721 Elite double oven)?
A technician diagnoses it on site and gives you the price in writing before any work starts.
