JennAir Radiant Cooktop Code F6E4: Keypad communication lost

What F6E4 means

F6E4 on a JennAir electric radiant or touch-control cooktop means the user interface, or keypad, and the user interface control have lost communication. The keys and the control behind them are no longer talking. As a result, the cooktop may ignore touches, shut off or display F6E4. It points us to the keypad link first. Elements may also switch off unexpectedly.

Common causes of F6E4

Communication link between keypad and interface control broken
Keypad failing
User interface control failing

✓ One safe check you can try

1. Switch everything off and let the glass cool. 2. Dry the touch area. 3. Interrupt the power at the breaker for around a minute and restore it afterward. 4. Try an element on low. If F6E4 stays on the display, call us. Please do not press the keys repeatedly or open anything.

! Why to stop there

The link is wired under the glass.
A cooktop with a lost link can behave unpredictably.
Resetting power will not repair a broken connection.
We test the link and parts and quote in writing.

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.

F6E4F6E4 questions

What does lost communication mean?

The keypad you touch sends signals to a control. F6E4 says those signals are not arriving. It can be a wire, the keypad or the control.

Can a reset solve it?

A reset can clear a momentary loss of contact for a while. If F6E4 returns, the link or one of the two parts needs repair.

Is it safe to leave on?

Turn all elements off when you are not at the stove. Until we check the cooktop, do not rely on it. We quote repairs in writing.
