JennAir range displays F3E0; oven will not heat or shows incorrect temperature

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Failed oven temperature sensor, Broken sensor wiring, Shorted sensor harness, Loose sensor connector

Safety: Turn off power at the breaker.

Locate sensor: Find the sensor probe inside the oven and remove its mounting screws.
Test sensor: Disconnect and measure resistance at room temperature (about 1050–1100 ohms). Replace if open, shorted, or far out of range.
Inspect harness: From the rear, check the sensor wiring for damage or shorts to chassis. Repair or replace as needed.
Replace sensor: Install a new JennAir-compatible oven temperature sensor and reconnect wiring.
