Bosch HBL8651UC 800 Series 30 in Double Convection Wall Oven E012 Error Fix: Oven Temperature Sensor Shorted

The oven cavity temperature sensor has a shorted circuit. The sensor resistance is reading near zero ohms. Check the sensor wire insulation — heat damage can cause the wires to touch, creating a short. Look for pinched wires where the sensor harness passes through the oven cavity wall. Measure sensor resistance — if near zero, replace the sensor. Also check for moisture in the sensor connector, which can cause a temporary short.
