The short answer
The manufacturer documents F0E2 with an instruction rather than a component: disconnect the cooktop from the power supply. That is how the code is classed — a state the control cannot leave while it is powered, rather than a part that has been identified as faulty. One proper disconnection is the documented fix; a code that survives it has become something else. If you do only one thing from this page, do the first diagnostic check: it splits the likely causes before anything is bought.
Error codes
Reference| Code | Meaning |
|---|---|
| F0E2 | Disconnect the cooktop from the power supply. |
What you observe, and what to record
- The panel holds the code and ignores input — A latched state behaves exactly like this and is why the documented remedy is a disconnection.
- Whether the kitchen was unusually warm or humid — Marginal connections and temperature protections both behave differently in a hot room, and a fault that only appears in summer is telling you that.
- How long the ${A} runs before the code appears — Immediately from cold, or well into a session — that interval is the most useful single number you can hand a technician.
Causes, most likely first on this cooktop
- A latched control state — First: the documented remedy is the manufacturer classing the code as recoverable, and it clears without a part being touched.
- A supply disturbance — Second: a brownout or a brief cut leaves the board holding a state it has no way out of.
- A marginal connection inside the cooktop — Third: intermittent contact is the mechanism behind a code that resets away and returns on its own schedule.
Check in this order, and why
- Disconnect properly, at the breaker — Switching the cooktop off at its panel does not remove power from the boards. Only the breaker does.
- Leave it off for a full minute — Short interruptions clear the display without clearing the state.
- Record how long it stays away — Minutes, days, or weeks — that interval decides whether this needs a technician.
What an owner can safely check
- Switch the cooktop breaker off for a minute — The documented remedy. At the breaker, not at the touch panel.
About 5 min
- Check whether the appliance is still in warranty — Worth two minutes before anyone is paid: the purchase date and the model number decide it, and some components carry longer cover than the appliance.
About 10 min
- Photograph the display with the code showing — Codes are easy to transcribe wrongly and a photograph is not. It also timestamps the fault, which matters if it becomes intermittent.
About 5 min
- STOP HERE — do not cycle power repeatedly — Repeating a reset at a standing fault tells you nothing new.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel — a capacitor can hold a charge after the power is off. An induction surface leaves the pan hot even where the glass beneath reads cool, so treat the cooking area as hot until you have checked it, and keep the residual-heat indication in view while you work.
When to call a technician
Call once the code returns after a proper breaker disconnection, and especially if it now returns within minutes. Bring the technician the interval between returns and anything that happened first — a spill, a power cut, work on the kitchen circuit. That context narrows a code with no named component far more than the number does. Clear access to the cooktop before the visit; access time is charged like any other.

What this page does not cover
This page reads F0E2 for Jenn-Air cooktops in general, from the manufacturer's shared code index. A code can be documented differently for one family, so where a model-line page exists for your unit it is the more specific answer and is linked below. Not here: wiring colours, connector positions and part numbers, which differ by family.
