KitchenAid Smart Oven+ F3E4: Reconnect the Attachment

Smart Oven+ wall ovens power their grill, steamer and baking stone attachments through a hub at the back of the oven. F3E4 is the code for an attachment that lost that connection.

What F3E4 Means on a KitchenAid Wall Oven

KitchenAid says F3E4 shows when a power attachment was in use and may have come unplugged; it applies to some models only. The Smart Oven+ attachments (+Grill, +Steamer and +Baking Stone) are powered through a hub at the back of the oven cavity. KitchenAid’s steps: roll out the rack, make sure the attachment is in the correct location, and push the roll-out back firmly until a tone sounds, then reset at the breaker if needed.

KitchenAid’s Steps for F3E4

Use oven mitts; the attachment and rack may still be hot.

1

Reseat the attachment

Roll out the rack and make sure the attachment sits in the correct location for your model.

2

Push it home

Slide the roll-out back firmly. KitchenAid says a tone sounds when the rack is in place.

3

Reset if it persists

Turn the breaker off for one minute, back on, watch for a minute and confirm the oven works normally.

If F3E4 keeps returning with the attachment seated, book a visit.→

KitchenAid F3E4 Questions

KitchenAid says only some models. It relates to powered attachments, which are a Smart Oven+ feature.

Clear the code first with the reset. If it stays clear, normal baking without the attachment is usually fine; if it returns, book a check.

The +Grill, +Steamer and +Baking Stone attachments, all powered through a hub at the back of the oven.

KitchenAid says a tone sounds when the rack is in place. No tone usually means it isn’t fully seated, or the hub isn’t making contact.
