What it looks like from the kitchen
The symptom this code usually arrives with
A code names the subsystem; the symptom is what sent you to look at the display in the first place. That page says what it usually turns out to be, cheapest cause first.
-
Electric radiant or induction One cooktop zone has stopped
On an electric or induction top a single dead zone means something different from a whole surface going out. Both are diagnosable from the front, and on induction there is a pan question worth asking before anything else.
- One zone dead, the others fine
- A zone that shuts itself off after a few minutes
- The whole surface unresponsive

What else belongs to the cooktops
On this make a code belongs to the appliance rather than to a product line. These are the other conditions this machine can display, and the models that can show this one — a display often has more than one thing to say, and the model number decides what any of it costs to put right.
Other codes this appliance can display

About KitchenAid induction cooktop error code E91
What KitchenAid publishes for E91 on a induction cooktop
Nothing. KitchenAid publishes E91 for the induction cooktop and states no meaning against it, so neither do we. A guess dressed as a cause is how somebody ends up buying the wrong board, and this archive would rather be short than wrong. What the code does narrow down is below, and what it means exactly is settled at the appliance.
Worth trying yourself, in this order
These are KitchenAid's own steps for E91 on a induction cooktop, and they are worth the five minutes: several of them end the call for nothing at all, which is why this archive is free to read before you book anything.
- Power unit down by turning off the circuit breaker(s) for one (1) minute.
- Power unit up by turning on the circuit breaker(s).
- Wait for the cooktop to cool down before using it again.
- Monitor the cooktop for one (1) minute to ensure the error code does not display again.
- Verify cooktop operation.
Then what
One more thing worth saying plainly: this code is not this badge's alone. KitchenAid shares its control platform with the other names in the same group, and the same page for E91 sits at the same address under more than one of them. That is useful rather than awkward — it means the code names the subsystem and the model number names the machine, so the plate on the door frame is half of every answer here.
The full KitchenAid code archive holds the rest, searchable. Tell us the model number and exactly what the display is showing and we will tell you what it points at before anybody is booked. We repair this equipment across Miami-Dade, Broward and Palm Beach.
