JennAir Range Code F3: Oven control or wiring

What F3 means

On JennAir electric, gas and dual-fuel ranges with electronic oven control, including the JES1750FS and JIS1450DS, F3 means there may be a problem with the oven control or the associated wiring. The electronics that run the oven have reported a problem, so the cycle stops and the display shows F3. The cooktop may still operate normally. The cooktop is generally unaffected.

Common causes of F3

Oven control failing internally
Wire harness issue at the control
Power disturbance upsetting the control

✓ One safe check you can try

1. Press Cancel and let the oven cool. 2. Turn the range off at the breaker for a full minute. 3. Restore power, set the clock and try a short bake. 4. If F3 appears again, switch the oven off and call us. Please do not remove panels or touch the wiring.

! Why to stop there

Control problems of this type cannot be repaired by resetting alone.
Live circuits behind the range are not safe for owners.
We test first, quote in writing and warrant our work for 30 days.

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.

F3F3 questions

Is F3 a sensor code?

No. Plain F3 names the oven control and wiring. The sensor codes in this series are F1 and F2, and the F3 E-codes narrow things further. Check the E-number if one follows F3, because it narrows the cause.

Can I keep using the cooktop?

Often yes, but if burners act strangely too, shut the range off at the breaker and call us. If it keeps coming back, book a visit rather than relying on resets.

What if F3 only appears sometimes?

Intermittent codes still need a visit. Connections that work loose with heat are a common reason. A pattern like that points to heat sensitive parts or a connector that works loose.
