The short answer
The manufacturer documents F0E8 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. The checks below run cheapest and safest first, and they stop where a meter on live terminals would be needed.
Error codes
Reference| Code | Meaning |
|---|---|
| F0E8 | 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 code is steady or intermittent — A fault that is present every time is far quicker to find than one that comes and goes, and the two are diagnosed differently.
- Whether the ${A} still does everything else it should — What still works narrows the search as effectively as what does not, and it is the question a technician asks first.
Causes, most likely first on this cooktop
- A held state after an internal timeout — First: the control noticed something it could not reconcile and stopped, which is what the disconnection clears.
- A brief interruption to the supply — Second, and the commonest trigger for a board to latch in the first place.
- Moisture or residue affecting a connection — Third: a spill that reached the seam produces exactly this intermittent pattern days later.
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
- Copy the full model number from the rating plate — Brand code indexes are shared across model lines, and the model number is what lets the code be read against the right one.
About 10 min
- Note which functions still work and which do not — Go through them deliberately rather than from memory. The list of what works is the fastest diagnostic information there is.
About 15 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 F0E8 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.
