E5 on a JennAir microwave is most often discussed as a microwave fault condition. Below: typical meaning, what you may notice, safe homeowner checks, and when JennAir Appliance Repair should diagnose on site.
Model compatibility: JennAir reuses codes across series and model years, so E5 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
E5 indicates a microwave electronics/sensor fault. Do not bypass door switches — call service if persistent. Never assume one forum post or generic chart overrides your rating-plate model. Independent technicians at JennAir Appliance Repair test the live appliance rather than guessing from the code alone.
Signs

The microwave displays E5 during operation
E5 appears without an obvious cause
The microwave behaves inconsistently with E5 shown
Why it happens
Possible causes
A sensor reading out of range
A wiring or connection issue
A control interpreting the reading as a fault

Often a single power-cycle after a documented user fix clears a stale message. If E5 reappears immediately, stop repeating resets and book JennAir Appliance Repair.
