The short answer
E2 on this cooktop means the control panel has switched off because the internal temperature of the electronic parts is too high, and the published remedy is to let the cooktop cool before using it again — that is what the manufacturer published for it, and no more. Let it cool as the manufacturer says and it returns; do not keep switching it back on while it is hot. One of the checks below is an owner check, and the rest of the work is behind a panel.

| E2 | The control panel switches off because of excessively high temperatures. The internal temperature of the electronic parts is too high. Wait for the cooktop to cool down before using it again. |
What the machine does alongside the code
- It happens sooner each time on a busy evening — Heat that has not fully left between sessions brings the threshold closer.
- The whole control panel goes off, not one zone — The published wording is about the control panel switching off, which is what distinguishes this from a single-zone trip.
What triggers E2, most likely first
- Not enough cooling time between heavy sessions — It goes first because it is the commonest version of what the entry describes: the electronics shed heat slowly, and starting a second heavy session before the first one has cleared reaches the threshold much sooner.
- Sustained high-power cooking, often with a hot appliance below — Running several zones hard for a long stretch, or cooking above a hot oven, adds directly to what the electronics have to shed.
- A sensor or control reading a temperature that is not there — Last and least likely: before blaming the reading, the heat has to be shown not to be real, because a false trip and a real trip look identical from outside.
Check in this order, and why
- Feel the cabinet below the hob after cooking — Warmth under the appliance is heat that should have left through the vents.
- Check every vent, grille and clearance around the appliance — This is the commonest cause and it is visible from outside.
- Ask what the appliance was doing when it tripped — Long runs, high settings and back-to-back cycles are the ordinary triggers and they change the diagnosis.
The reset, then the owner-safe checks
- Repeat the same use pattern once and watch for the trip — If it trips at the same point, the thermal path is the fault; if it does not, the first trip was a one-off.
About 45 min
- Let the cooktop cool completely, clear the vents and the space below, then cook the same way once more — Do not put anything cold or wet on the glass to hurry it: thermal shock cracks glass.
Tools: vacuumAbout 45 min
- Cut power at the breaker for a minute before the retry — Clears the stored code so that what you see next is live rather than remembered.
About 5 min
- STOP HERE — the cooling fan and the sensor are inside — Both sit behind a panel next to live terminals, which is where an owner check ends.
Before anything is opened
Safety
Isolate the cooktop at its circuit breaker before any panel comes off — a capacitor can hold a charge after the power is off, and this is a fixed high-current appliance rather than one you unplug. Put nothing cold or wet on hot glass. On a gas model, if you smell gas, leave the building and call the gas utility from outside.
When this is a service call rather than a reset
Call at once if the appliance is hot enough to be uncomfortable to touch, if you smell hot plastic, or if it trips cold.

What this page does not cover
This reading applies to the KitchenAid cooktop line as a whole, not to one family or model. It does not cover what differs between model lines — wiring colours, connector positions, part numbers and service-mode sequences — which are in your own model manual and which a technician matches to the rating plate rather than to this code. Where a family- or model-specific page for this code exists, it is linked from the code index below and it is the more specific answer.
