Safety: Turn off power at the breaker before removing any panels.

Inspection steps:

Access the lower oven temperature sensor (if a double oven) at the rear wall of the lower cavity.
Remove the mounting screws and gently pull the sensor into the cavity to access the connector.
Disconnect and measure resistance at room temperature. Expect approximately 1050–1100 Ω at 70°F. Compare to Wolf service specs if available.
Check the harness for heat damage or chafing where it passes through the liner or near the convection fan housing.
Verify the connector at the control board is fully seated and free of corrosion or burnt marks.

Corrective actions:

If resistance is out of spec or intermittent when you gently flex the leads, replace the lower oven temperature sensor.
If wiring is damaged, repair with high-temperature-rated wire and connectors or replace the harness.
If sensor and wiring test good but E02 remains, the control board is likely defective and should be replaced by a qualified technician.

Wolf oven shows E02 and will not start or prematurely shuts off during preheat.
