Neff circo therm need to replace cooling fan
Isolate mains.Remove oven cavity back panel (4/6 phillips or 4/6 Torx 20 screws)Remove fan blade (reverse thread nut)....this is sometimes where you come unstuck, because the blade just won't budge.If that happens I normally then remove the back panel of the unit itself (doesn't need to come all the way off, I will usually leave the mains connections on and let it fall back as far as it will go safely...may have to loosen the cable clamp to get some slack on the mains)You will now see the other side if the fan motor.Remove the L and N (not pole sensitive so they can go on the new one either way).Remove the 3 Torx20 screws holding the fan in position. (some models have an extra spacer ring so be careful you don't lose them)Go back to the cavity and use something to give the motor shaft a whack to release the fan blade, bearing in mind that if it does budge the motor itself is going to fall out the back (stick an old towel etc to cushion the fall and protect the terminal block etc).The new fan usually comes with the blade attached, separate the parts, install the motor, attached electrical connection and then the fan blade, make sure its tight. At this point I would close up the back and just hold in place with one screw and test that the fan works. (don't forget that the oven will not operate when the clock is flashing, so set any time on the clock before selecting circotherm)If everything looks ok, get it back together and in housing and run upto 150 or 200 degrees as a last test.Good luck, let me know how you get on or if you need any further clarification. Please post the outcome as this will assist other users of the site looking for solutions to similar problems.All the Best.
