Oven PTC temperature sensor is short circuited

From Service Manual 634203, p.15:

1.Verify functioning of PTC (ambient temp should read 545 ohm), then replace if necessary.

2.Disconnect the sensor and measure resistance at the sensor body. Expected: 10 kΩ to 12 kΩ at 77°F (25°C).

3.Check the sensor harness for opens and shorts. Back-probe the sensor pins at the control board connector; a reading outside 5 kΩ to 50 kΩ indicates a failed sensor.
