JennAir Range Code F1: Oven temperature sensor, control or wiring

What F1 means

On JennAir electric, gas and dual-fuel ranges with electronic oven control, including the JES1750FS and JDS1750ML, a bare F1 means there may be a problem with the oven temperature sensor, the control, or the wiring that links them. The oven cannot trust its own temperature reading, so it stops the cycle and shows the code. The cooktop side normally keeps working.

Common causes of F1

Oven temperature sensor out of its expected range
Damaged sensor wiring or a loose connector
Oven control that cannot read the sensor signal

✓ One safe check you can try

1. Press Cancel and let the oven cool down. 2. Turn the range off at the breaker for one minute, then back on. 3. Start a short bake at a moderate temperature and see if F1 returns. 4. Take out foil or oversized pans that crowd the back wall of the cavity. A code that comes back needs a technician with a meter.

! Why to stop there

A bad sensor and a bad control look alike on the display, so only testing tells them apart.
Dragging the range out to reach the wiring is risky, especially with a gas line attached.
We quote before any work and cover the repair 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.

F1F1 questions

Can I use the stovetop with F1 on the display?

Usually yes, since the surface burners do not depend on the oven sensor. Keep the oven off until the sensor circuit has been checked, and call us if the burners behave oddly too.

Is F1 the same on a wall oven?

The wording is the same on JennAir wall ovens, but the parts and layout differ. This page is about the range, and we diagnose each appliance on its own. Do not rely on it, because the wiring and the layout inside differ.

Why did the oven stop mid-bake?

When the control loses a believable temperature reading, it shuts the heat off for safety. A reset may restore it briefly, but a weak sensor tends to fail again, so treat any repeating F1 as real and not a glitch.
