JennAir Range Code F1-L: Oven sensor reading problem

What F1-L means

JennAir electric and gas ranges with the older display, for example the JES1750FS or JGRP430WP, show F1-L when the oven temperature sensor, the control or the wiring may have a problem. The trailing L is simply part of the displayed code. Baking stops, the oven cools, and the code replaces the time of day. A technician narrows down the cause by testing each part in turn.

Common causes of F1-L

The oven temperature sensor has failed
A problem on the oven control
Wiring to the sensor is damaged or loose

✓ One safe check you can try

1. Let the oven cool fully. 2. Press Cancel. 3. Leave the range without power for one minute, then restore it. 4. Try one short Bake. 5. If F1-L is back, stop using the oven and call us. The sensor and its wiring are not meant for owner repair.

! Why to stop there

The cavity sensor and wiring are not meant for owner repair.
Resets seldom correct a sensor that has failed.
A visit with a diagnosis avoids repeated purchases of the wrong part.

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.

F1-LF1-L questions

Is F1-L different from the other F1 sensor codes?

The meaning matches F1-2 and F1-3: the oven temperature sensor, the control or the wiring. The letter or number simply labels the entry on the control.

Can a repair wait?

The oven will not do its job while the code is active, so waiting only keeps the oven down. The sooner it is checked, the sooner you can bake again.
