Amana AER6303MFS 30 in 4.8 cu ft Electric Range with Self-Cleaning Oven and Storage Drawer F3 Error Fix: Open Oven Temperature Sensor

The oven temperature sensor (RTD — Resistance Temperature Detector) circuit is reading as open (infinite resistance). The ERC cannot monitor oven temperature and will shut off heating as a safety precaution. Check the sensor wire harness connection at the back of the oven cavity and at the ERC board — a loose or corroded connector is common. Inspect the wiring for breaks or heat damage, especially where the harness passes near heating elements. Measure the sensor resistance with a multimeter — it should read approximately 1080 ohms at 70°F. Replace the sensor if it reads open.
