Error codeF1E4
ApplianceMicrowave
Quick answer
F1E4 names a control board on over-the-range JennAir microwaves and a manager or power relay on built-in ones.
Model compatibility: JennAir reuses codes across series and model years, so F1E4 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
JennAir's over-the-range page lists the Appliance Control Board or wiring for F1E4; the built-in page lists the Microwave Appliance Manager or Microwave Power Relay.
Which microwave do you have?
JennAir describes F1E4 in two ways, depending on the microwave type.
Type
What the help page says
Over-the-range
Oven could not execute the function; the Appliance Control Board or its wiring may be at fault.
Built-in
The Microwave Appliance Manager, the Microwave Power Relay or the wiring may be at fault.
JennAir explains neither the difference nor any cause. With the entries in conflict, both are shown here and none is chosen.
Plain meanings of the terms
A control board or an appliance manager is a circuit board that coordinates what the microwave does.
A power relay is an electrically operated switch, and JennAir leaves open what it switches here.
These are plain dictionary-style meanings, not manufacturer statements about your unit.
The reset
Cut power at the breaker for 60 seconds.
Restore power.
Keep watch for a minute to see if F1E4 comes back.
Check that the microwave operates.
Both help pages call for this same procedure.
If F1E4 stays
JennAir’s over-the-range page says a qualified technician may be needed. Boards, a relay and wiring are all in play, so hands-on checking happens inside the cabinet and is not owner work.
Codes in a similar spot
F1E1 has differing wording between the two microwave pages as well.
F6E0 lists the Appliance Control Board on over-the-range models.
