The short answer
FC E0 names the electrical supply, the associated wiring, or the induction module — so it spans everything from the wall to the part that drives the coils. The supply is the cheapest of the three to check and the only one an owner can gather evidence about, which is where this page starts.

| FC E0 | There may be a problem with the electrical supply, the associated wiring, or the Induction Module. |
What you observe, and what to record
- The cooktop will not start, or starts and drops out — A supply that sags under load looks exactly like this.
- Whether anything on the same circuit misbehaves — Lights that dim, a breaker that has tripped before, or another appliance acting up all move the search away from this one.
- 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 loose or corroded connection in the supply circuit — First: it produces every symptom above, it worsens on its own, and it is cheap to find. High-current joints that relax heat, and heat loosens them further.
- A missing or weak supply leg — Second: it is why part of a cooktop can work while the rest does not, and a double-pole breaker can lose a pole while looking perfectly normal.
- Wiring between the supply and the induction module — Third: inside the appliance, and intermittent in a way that mimics a supply fault exactly.
Check in this order, and why
- Cycle the cooktop breaker fully off and on — A partly tripped pole is invisible from the front and common.
- Watch the kitchen lights as the cooktop starts — Two seconds of observation with real diagnostic value.
- Map which zones work at which power levels — It separates a supply problem from a module problem.
What an owner can safely check
- Switch the cooktop breaker fully off and back on — A definite off position, not a nudge back.
About 5 min
- Wipe the control area with a barely damp cloth and dry it — Never sprayed cleaner, which runs into the seams. A damp panel produces faults that look electrical and are not.
Tools: microfibre clothAbout 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 — the module and the supply connection are not owner spaces — Both carry the largest currents in the kitchen.
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. A cooktop is reached from below through the cabinet, never by prying the glass up: it is bonded to its frame and a lifted corner is a cracked top. Surface areas stay hot long after the display clears.
When to call a technician
Call an electrician if lights dim, if the isolator is warm, or if only part of the cooktop works. Call an appliance technician once the circuit has been confirmed healthy and the code still stands. An induction module is among the dearest parts in the appliance, so it is worth eliminating the supply properly before anyone orders one.

What this page does not cover
This page reads FC E0 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.
