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
On the same appliance
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
The cooktop is too hot.
An object, liquids, or soils are putting pressure on the control panel
There is an internal communication error on the touch control module

About KitchenAid electric and induction cooktop error code F43
What KitchenAid publishes for F43 on a electric and induction cooktop
There may be a problem with the Cooktop Power Control Board, or the associated wiring. That sentence is KitchenAid's own, read off its published support page for this condition on a electric and induction cooktop rather than worked out from the outside. Everything under it is ours, written from what this equipment does in Miami kitchens.
The useful part of that is the noun: Cooktop Power Control Board. A published cause on this platform names a circuit rather than a component, which is the single most useful thing to know before anybody orders a part — it tells you which side of the appliance a technician starts on, and it does not tell you which piece of that circuit has moved out of range.
The power cycle is a test, not a repair
The whole of what KitchenAid publishes to do about F43 on a electric and induction cooktop is a one-minute cycle at the breaker — on the same page that says the condition points at the cooktop power control board. Do it, and read the result rather than the instruction. Cutting power clears the stored code and makes the control re-read every circuit from cold. If the condition was a one-off — a control interrupted mid-write, a reading that went out of range once — the code does not come back and there is nothing to repair.
If it comes back, the reset has told you something. The condition is live, the circuit is still reporting, and a second power cycle will not change that. From there it is a diagnosis rather than a procedure.
KitchenAid's own steps, in its order
- Power unit down by turning off the circuit breaker(s) for one (1) minute.
- Power unit up by turning on the circuit breaker(s).
- 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 F43 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.
