JennAir Range Error FC E4 Points to the Wi-Fi Antenna or Its Wiring

What FC E4 means

On JennAir electric, gas and dual-fuel ranges with electronic oven control and Wi-Fi, such as the JDS1750ML or JIS1450DS, FC E4 means the Wi-Fi antenna or its wiring may have a problem. This is about the range's own hardware rather than your router. The code appears on the display and the connected features may be unavailable, but the oven and cooktop still heat.

Common causes of FC E4

The Wi-Fi antenna is not working correctly
Wiring to the Wi-Fi antenna is loose or damaged

✓ One safe check you can try

1. Turn the range off at the breaker for one minute, then restore power. 2. Leave the range alone for one minute and see if FC E4 returns. 3. Check the range works normally by running the oven briefly. 4. If the code returns, call us and mention the exact code.

! Why to stop there

The antenna is part of the range, so restarting your router will not change the result.
Opening the range to reach the antenna wiring is not a safe owner task.
We test and quote the repair in writing first.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

FC E4FC E4 questions

Is my Wi-Fi router the problem with FC E4?

Not according to the code. FC E4 points to the range's Wi-Fi antenna or its wiring, which is inside the appliance, so a router restart is unlikely to change the result.

Do I lose cooking functions?

No. Only connected features are affected. The oven and cooktop continue to heat as usual, so you can keep cooking while you wait for a repair visit.

Is FC E5 the same?

FC E5 has the same official meaning, antenna or wiring. The last digit helps the technician see which check triggered, so tell us the full code when you call.
