JennAir Wall Oven Error Code
The oven RTD temperature sensor is reading open circuit. The wall oven cannot regulate temperature and will not heat. The sensor plugs into the rear wall of the oven cavity. On double wall ovens (JJW3830LM), identify which cavity is displaying the error — upper and lower ovens have separate sensors.

When your JennAir Wall Oven displays the F3-E0 code, it means the appliance's self-diagnostic system has detected a fault that requires attention. A single power cycle that clears the code is not a reliable fix if the underlying cause has not been addressed.
Based on our technicians' experience servicing JennAir Wall Ovens, the F3-E0 code is most frequently triggered by:
Before scheduling a service call, work through these steps in order:
If the F3-E0 code returns after completing the steps above, a component has likely failed. Continuing to run the appliance with an active fault may cause secondary damage.
JennAir Support Center technicians carry the most common replacement parts on every service vehicle. In most cases, we diagnose and complete the repair in a single visit.
Typical ranges based on our service history:
All repairs include a 30 day parts and labor warranty. A written estimate is provided before any work begins.

Call (800) 555-0190Temperature inaccuracy in JennAir wall ovens is most often caused by a failing oven temperature sensor (RTD probe) or a weak bake/broil element that heats but at reduced wattage. JennAir V2 vertical dual-fan convection ovens may also experience uneven heating if one of the two convection fans has failed.
The self-clean cycle requires the door lock mechanism to engage before heating begins. A failed door lock motor, a broken latch hook, or a faulty door switch will prevent self-clean from starting. Do not attempt to bypass the door lock — it is a safety interlock.
V2 is JennAir's vertical dual-fan convection system with two fans stacked vertically for more uniform airflow. If convection performance has degraded, one or both fan motors may have failed, or the convection heating element may be weak. All V2 components are available as genuine JennAir OEM parts.
Most JennAir wall oven repairs are completed in a single visit of 1-2 hours. Common repairs like sensor or element replacement are straightforward. Control board replacements may take slightly longer due to programming. We carry the most common parts on our service vehicles.
