The short answer
The manufacturer's published entry for E_13 gives a remedy rather than a component: power the unit down at its breaker for about a minute, then bring it back. That phrasing is deliberate — the code is documented as a transient that the control latched rather than a part that has failed. If it comes back after a proper power-down, it is no longer transient and the next step is a technician rather than another reset.
Error codes
Reference| Code | Meaning |
|---|---|
| E_13 | Power unit down by turning off the circuit breaker(s) for one (1) minute. |
What you observe, and what to record
- The code appears and the display stops responding usefully — A latched state holds until power is removed, which is what the documented remedy is for.
- Whether the code clears when power is removed — Cut the supply for a minute and watch. A code that clears and stays away behaves completely differently from one that returns within a cycle, and nobody but you can observe the difference.
- What the appliance was doing at the moment it appeared — Starting, part-way through, or sitting idle. Each points at a different circuit, and it is forgotten within a day if it is not written down.
Causes, most likely first on this cooktop
- A momentary supply disturbance — First, because it explains the documented remedy exactly: a brownout, a surge or a brief interruption leaves the board in a state it cannot leave on its own.
- An internal communication hiccup between boards — Second: these appliances run more than one board, and a message lost between them latches rather than retries.
- A connector that is marginal rather than broken — Third: a connection that works most of the time produces a code that clears on a reset and returns days later.
Check in this order, and why
- Do the reset properly, at the breaker — Cutting power at the breaker is not the same as switching the appliance off at its panel, and only the first removes power from the board.
- Count how long it stays away — Minutes, days or weeks — that interval is the most useful thing an owner can record.
- Note what else is on the circuit — A repeat code on a circuit shared with a heavy motor load is worth mentioning.
What an owner can safely check
- Switch the breaker off for about a minute — switch the cooktop off at its breaker. A minute is long enough for the boards to lose their stored state.
About 5 min
- Keep a short log of when the code appears — Date, what the cooktop was doing, and how long it had been running. Two entries make a pattern; one does not.
About 5 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 reset repeatedly — Cycling power at a fault that keeps returning tells you nothing new and stresses the supply side.
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. Do not pour water onto hot glass to cool it and do not work on a top that is still warm: thermal shock cracks a ceramic surface, and a cracked top takes the whole appliance out of service.
When to call a technician
Call once the code returns after a proper breaker reset, and call rather than repeat the cycle if it now returns within minutes. A technician will want the interval between returns, what else shares the circuit, and what the cooktop was doing each time — collect those and the visit is much shorter.

What this page does not cover
This page reads E_13 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.
