We have a Thermador CM302 built-in double oven. The convection motor assembly in the lower oven emits a vibration-type noise when the convection fan is spinning. I removed the fan from the spindle and unfortunately the squeal is still there even when running the motor without the fan attached. So the motor probably has to be replaced. I may attempt to do this myself if it is not too difficult. This brings up a couple of questions: (1) Can the motor be replaced without removing the oven from the wall? (2) Does the motor just plug in to the power supply or is there wiring involved? Thanks, -Todd

Todd for Model Number CM302

ANSWER Hello Todd. Here are the instructions from the manufacture for the motor 00494266. Hope this helps. 1. Turn off the electrical power to the oven. 2. To make servicing easier, remove the oven door. 3. Remove the racks from the oven. 4. Remove the front screws from the left and right oven rack supports and remove the supports from the oven liner. 5. Remove the screws from the convection baffle and remove the baffle from the back of the oven liner. 6. Remove the hex nut from the front of the convection blade. NOTE: The nut has leftrotating threads. 7. Remove the flat washer and e-ring from the convection blade and remove the blade from the motor shaft. 8. Remove the screws from the pan and remove the pan. 9. Remove the motor screws from the bracket and remove the motor from the bracket. 10. Disconnect the two wires from the fan motor terminals. 11. Connect the brown wire (#45) to the right terminal of the new convection fan motor, and the white wire (#44) to the left terminal, then install the motor assembly. 12. Reassemble the oven. The wires should unplug, so no rewiring is need.
