The short answer
E_22 is documented with an instruction rather than a named part. The manufacturer's entry says to switch the cooktop off at the breaker for around a minute and restore it, which tells you the code is treated as a state the control could not get out of by itself. 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_22 | 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 anything else about the appliance changed first — A noise, a smell, a slower cycle or a poorer result in the weeks before the code usually dates the fault better than the code does.
- 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.
Causes, most likely first on this cooktop
- A board that has latched a fault it can no longer clear — First: the remedy is documented precisely because this is what the code usually is — a held state, not damage.
- A supply event at the outlet or the breaker — Second, and it is why the documented reset is at the breaker rather than at the panel: the point is to remove power, not to restart the software.
- A loose or heat-cycled connector — Third: intermittent contact is the mechanism behind a code that comes back on a schedule of its own.
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
- 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
- Stop using the ${A} if anything smells hot or looks scorched — Discolouring at a connection or a plug is heat, and heat at a connection does not improve on its own.
About 5 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. 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 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_22 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.
