How to test an oven RTD temperature sensor
Most electronic ovens use a platinum RTD probe, which works the opposite way to an NTC: resistance rises with heat. Many common sensors read about 1,080 Ω at room temperature and climb roughly 2 Ω per °F.
Before you start
- Unplug the appliance or turn off the breaker before opening panels or disconnecting parts
- Take a photo of the wiring before removing any wire
- Resistance and continuity tests are done with power OFF and the part isolated
