SOURCE: fan oven not heating, bosch hbn 202t

the fan oven element is separate from the grill element. the problem is that the circular element round the fan is blown. remove the back panel of the oven and you will see the element. replacement is easy. on most bosch, the element is removable from inside the oven but for some you have to remove the oven and take off the back casing

SOURCE: Bosch HBN 455 Oven Cooling-Fan Issue

Our HBN655 had similar issues- the upper cooling fan would cycle on and off on a relatively quick duty cycle until the whole mess cooled off enough and it shut off.
My workaround is to turn the temperature dial off but leave the oven function dial on to BAKE. This seems to force the fan to stay on; then we shut it off a while later and avoid the annoying fan cycling.
(note- 2 years ago, our fan became intermittent, varying speed, etc... for about 2 months before it quit entirely. When that happened, the oven started to heat then the thermal cutout kicked in and the oven shut down entirely. We ended up replacing the fan and that fixed the bug... except now it's starting to act up again...)
(also note- the racks on this beast have a faulty design. if you have a heavy casserole and slide the rack out all the way, it tends push the sidewalls apart and the rack drops. I spoke with Bosch about this and they sent me new racks, no charge... so they know there's a problem. But the new racks don't fix the bug; they just make it harder to reproduce. I have actually had one rack fall with 2 piping hot casseroles on it. Fortunately no one was hurt.)

SOURCE: My Bosch HBN 5605 .0B oven has a 15-20 degree

I detected a similar problem following the sudden appearance of Err1 in the display. (Oven 4-5 years old, and the grill element failed when it was 3-4 years old). This indicated a temperature sensor problem. My local dealer came with his Thermocouple and confirmed an "under temperature" reading on the standard and baking settings. I agree that the fan setting is probably OK. He replaced the sensor. I monitored the situation for a while and was not happy because an under temperature could be quite dangerous when cooking certain foods, and also causes problems when baking bread.

The location of the oven sensor is also a problem because it is at the top right by the grill which also serves as the top heat source.

I had corresponded with Bosch about this and their response was, frankly, less than satisfactory. In the end I decided to call out their engineer (cost £85-ish) who wired my oven up to his computer. In the end he said that the oven was working as it should be (despite it taking a very long time to actually reach the target temperature of 200C.

In my view of I want 200C, then I should get 200C, not an approximation.

Interestingly the secret info (not in the manual) is that the temperature bar readout does not indicate that it has reached the actual temperature, but may be 90% of the temperature (so if you want 200C you get 180C.

An unsatisfactory solution is to get an oven temperature of the meat probe type and put that in the oven, then you will get a more accurate reading of the temperature. You would need one that goes above 200C (my first one only goes to 200 but I have found another that goes to 250C). Mine is by CDN model DTP482, any good cook shop should stock this.

Any suggestions on how to remove covers on lights in Ilve oven so I can replace globes? Tried warming oven as suggested but they wont budge. Is the only solution to get an Ilve technician?


when you go to the service agent to get the correct bulbs ( (need to be pyrex glass ones as normal bulbs will not stand the oven heat) ,ask them how to remove
the fat from cooking gets in the glass threads and then goes to carbon , making it very hard to turn the covers
maybe a oven cleaner sprayed around the glass may help release the threads

How do I replace the fan in a Fisher & Paykel 60cm oven


ill assume your referring to the cooking fan you see inside the oven and not the outer cooling fan, you will need to turn the breaker off outside to cut power to the oven then you will have to take the oven out of the wall and remove the back cover then its normally just 3 screws and the nut on the inside of the oven that holds the fan blade on (which is reverse threaded by the way) and it should come out

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.

I have a Neff double oven U1721NOGB/02. I need to replace the element in the bottom oven. It would seem the fan needs to be removed as part of this process but it isn't clear how to. How do you remove...


Remove the nut and the locking washer and then stop the spindle from turning ensuring that you don't damage the thread. Then spin the fan vigorously round and round back and forth whilst pulling fan towards you until it releases or detaches from the shaft, then pull off. If you're unable to turn the fan on the central spindle, try a little WD40 ensuring you burn it off by heating the oven afterwards. Reminder: ensure you don't damgae the thread..... Rgds Damian

Replace oven fan motor


Take out the shelves and side hangers. SWITCH OFF.
There is usually a panel at the back of the oven cavity, undo the screws around it to access the fan blade. At this point you should be able to determine if there is another panel that the fan mounts onto that comes out through the front. (unlikely). Undo the centre nut on the fan blade which is usually a left hand thread - turn clockwise to undo. Take off the fan blade.
Next you gotta get to the rear of the oven and remove the back panel to access the fan motor. Once inside note down where the wires go. Remove wires from motor.
Back inside the oven cavity you will find screws that hold the motor in place (often three). Have someone hold the motor while you undo them. The motor should now be withdrawn from the rear.
Replace motor in reverse order.

Replacement of fan oven element on Nef U1721


Hi Steve...yes, these are a pain! Remove the centre fan nut (which is anti-threaded) then lever off the small locating washer underneath. If you are lucky, you will be able to now pull the fan blade off of the motor shaft. However, very often they won't budge!. If you try to knock it off, it is so easy to damage the fan motor (about £80!!). It is possible to leave the top bracket screwed to the oven and unclamp the element from it. I have come across three different typed of clamps so far. One is very easy to do. You can then remove the clamp from the new element and once the element is in place, use the old clamp. It's a fiddle but quite do-able. I have also come across these where the top clamp has been previously removed altogether by engineers on previous repairs! Hope this all helps a little....

Remove rear panel in back of oven, there you will see the fan,remove fan blade,usually left hand thread, and remove screws that hold fan, if they are not accessable from inside the oven then you will have to remove oven from housing, and remove rear outer panel to access fan screws and connections.
Remove fan and replace in reverse order.,don't forget the nut that holds the fan is a left hand thread.
Plz rate this solution.

Neff fan element


All of this can be done with the oven in situ. Take the back off if you like, but its un-necessary, dirty and time consuming. So here we go: Power off at mains. Remove 4 screws holding plate which guards the fan. You will be faced with the fan partially obscuring the top element retaining screw. At the centre of the fan spindle is a reverse threaded nut. WD40 the nut. Wait a minute or so and using a socket wrench and a flick of the wrist, the reverse thread nut should losen v easily. Having mastered the lock nut, tap the washer and it should become loose enough to remove by hand. If not, it just needs a little gentle persuasion with a flat head screwdriver where it sits on the fan itself. The grime will loosen and it will pop off. Squirt some WD40 onto the fan spindle, and wait a couple of minutes. Ignore any advice to lock onto the threaded spindle because if you damage it, your relatively cheap repair will become pretty expensive. Simply use a locking mole grip on the fan itself where the locking nut sits against it and pull and twist gently away from the spindle. You will be surprised how easy this is. Very little chance of damage. You can then access all 5 element retaining screws. Gently lever out the left foot of the element from the oven housing. Remove the spade connectors from the old element. Reversal of these instructions to fit the new element. Restore mains power. Reset clock or main oven will not work.

REMOVAL OF FAN


Ha - I found the solution myself. You need to remove the 3 screws securing the fan motor. Once you've done this, you can wiggle the fan a few mm, far enough to be able to remove the top element screw.
