Thermador Cooktop F4 on Older CIT365DS and CIT304E Induction Models: Pan Too Near the Touch Panel

What F4 means

Older CIT365DS and CIT304E induction cooktops display F4 when a pot or pan sits too close to the control panel. Current Thermador induction cooktops use F4 for a different message, so this is the older table only. The panel can get warm from hot cookware beside it, which is why the cooktop stops cooking until the panel cools and the pan is moved.

Usual causes of F4

Cookware too near the touch key panel
Hot item resting on the controls
Panel overheated from nearby cookware
Touch panel misreading heat even with the pan centered

✓ A safe check worth trying

1. Check where the pan sits and slide it away from the control panel. 2. Make sure nothing hot is lying on the touch keys. 3. Remove any hot item and wait for the panel to cool. 4. Restart the element. If F4 returns, call customer service.

! Why you should stop here

A panel that overheats with nothing near it is a board or sensor issue.
The glass top and panel are not meant to be lifted at home.
We give a written quote, and check older parts by model number.

Taking off a panel yourself does not by default void a manufacturer warranty, yet it can lead to accidental damage, and some manufacturers attach their own service terms. Read your warranty paperwork, or ask us, before you decide.

F4F4 questions

Is F4 only about pan position?

On this older table, yes: the pot or pan is too close to the control panel. If you keep the cookware clear and F4 still shows, the panel itself may be reading wrongly.

How long until the panel cools?

The manual gives no time. Take the hot item away and wait for the panel to cool by touch before trying again. If F4 returns even then, call for service.

Does current Thermador use F4 the same way?

No. Newer induction cooktops list F4 as overheated electronics. This entry applies to the CIT365DS and CIT304E table only, so check your model first.
