Questions & Answers

For Bosch Wall Oven Temperature Sensor (Part Number: OEM12225816)

Joseph for Model Number HBL8450UC/07

If I remove the two screws securing the temperature sensor to the inner oven chamber and attempt to pull the temperature sensor out (to measure the ohms resistance at room temperature) the covered wires only come out so far (two inches) and seem to be 'at rope's end.' Should I try to force the wiring to come out further or do I have to completely remove the oven assembly out of the cabinet to get to the other end of the temperature sensor wiring to measure resistance?

Joseph, based on the information provided, it sounds like the connector on the sensor is getting hung up and should not be forcefully pulled. If the connector will not maneuver out through the front, the next step would be to access it from the back.

Lisa, the oven sensor will read the oven temperature and tell the control board whether to turn the elements on or off. Typically the relays on the control will fail to open and close properly and therefore you get an inconsistent temperature. You can check the sensor with a multimeter for resistance, it should read about 1080 ohms at room temperature. If the readings are good, you would need to replace the control board, the part number is 00655359

Francis, the model number provided is registering as a Thermador/Bosch model and may need to be verified. However, as this model does register as such, the sensor 00642855 would work with this model. Usually, brands will not cross over in regards to parts.

Colleen,
The first thing you will need to test is your temperature sensor for a resistance reading of 1100 ohms at room temp. Any reading out of this range plus or minus 10% and the sensor would need to be replaced.

John,

With the unit not heating in regular bake cycle but does work in the quick preheat then this would most likely be a faulty control board.
