Thermador Induction Range Cooktop F4 / E7015: Electronics Overheated, All Zones Off

What F4 / E7015 means

F4 or E7015 on the induction side of Thermador Pro Harmony and Masterpiece MRI304DL ranges means the electronics overheated and all cooking zones switched off. The Ranges page prints E7015 under both F2 and F4, and the Induction Cooktops page lists F4 in the single-zone group, so we confirm on site which applies. Other generations use F4 differently.

Usual causes of F4 / E7015

Electronics overheated

✓ A safe check worth trying

1. Turn all zones off. 2. Allow time for the cooktop to cool. 3. Check that nothing blocks the vents. 4. Try a low setting on one zone. If every zone shuts down again, call us. Mention which code appeared first.

! Why you should stop here

Heat sources inside the range need testing.
Fans and airflow may be involved.

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.

F4 / E7015F4 / E7015 questions

Why did every zone stop?

On the Ranges page, F4 is described as all cooking zones switching off together. That fits a shutdown protecting the electronics rather than one hot pan.

Why do the manuals disagree a little?

The Induction Cooktops page groups F4 with the corresponding-zone entry. Since the two pages differ, we confirm what your unit actually did. Photos of the display help.

Is E7015 the same thing?

The Ranges page prints E7015 under both F2 and F4, so it is shared between them. Tell us which code you saw first when you call.
