JennAir Range Code F3 E1: Oven temperature sensor circuit

What F3 E1 means

On JennAir electric, gas and dual-fuel ranges such as the JDS1750ML and JES1750FS, F3 E1 points to the oven temperature sensor, the control, or the associated wiring. It is the sensor-reading member of the F3 family, so the oven stops when the reading looks wrong. On JennAir double wall ovens the same code specifically refers to the lower oven sensor.

Common causes of F3 E1

Oven temperature sensor out of range
Sensor wiring or connector problem
Control misreading the sensor signal

✓ One safe check you can try

1. Cancel the cycle and let the cavity cool. 2. Take out foil, stones or tall pans that touch the rear wall. 3. Switch the breaker off for one minute, then on. 4. Run a short bake. If F3 E1 repeats, the sensor circuit needs testing by a technician.

! Why to stop there

Sensor readings must be measured at temperature to be trusted.
Replacing parts without measurements often misses a wiring problem.
We give the price in writing before work and 30 days of warranty after.

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.

F3 E1F3 E1 questions

Does F3 E1 apply to the whole range?

It relates to the oven cavity sensor only. The cooktop usually works independently of it, so surface cooking is normally still available while the oven waits for a sensor circuit check.

Why do wall ovens say lower oven?

Double wall ovens have two sensors, and the code identifies the lower one. A range has one oven, so the code just means the oven sensor circuit. That is why the same code reads differently on different appliances.

Can I clean the sensor?

Do not wipe or scrape near it while the oven is hot. A dirty sensor is not the official cause, so the circuit itself needs checking, and we measure it with the range powered safely.
