Common Causes
- 1Sensor failed
- 2Connector loose

Step-by-Step Troubleshooting
- 1
Access the sensor through the rear panel — it enters the oven cavity secured by screws
- 2
Disconnect and measure resistance: approximately 1080 ohms at room temperature (70F)

An infinite/OL reading confirms open circuit — replace the sensor

Pro Diagnostic Tip
The Amana oven uses the same RTD sensor as Whirlpool and Maytag (1080 ohms at 70F, ~1500 ohms at 350F). On self-cleaning models, heat degrades the sensor faster. Check the wire harness first — on Amana AGR ranges, the sensor wire runs along the rear wall and breaks at stress points from heat cycling.
