Quick answer
RTD ERROR — the oven RTD (temperature detector) circuit is open or shorted per JennAir documentation.
Model compatibility: JennAir reuses codes across series and model years, so RTD ERROR may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.

Important safety warning. Do not open internal panels, access high-voltage wiring, or bypass any safety device. If you ever smell gas, stop immediately, do not operate any switches, leave the area and contact your gas provider and a qualified technician. If you see smoke, sparks, a burning smell, or water near electrical parts, switch the appliance off at the outlet if it is safe to do so and call a professional.

When to call a technician
Follow the manual: call a qualified appliance technician when RTD ERROR is displayed. Do not use the oven for normal cooking until the RTD circuit is diagnosed.
