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.

Why wont fan turn off after use in oven bosch model hbn 13n5,1b


It should turn off after a while. The fan is actually the cooling of the case, it runs longer if I have used a higher temp setting. If it does not stop after app. 20 min something is broken.

Self cleaning


Set back on self clean, then after about a minute, switch off. The lock should disengage.

I have a Bosch HBN 455 double oven with the convection oven on top, and a regular oven on bottom. The unit is about 5 yrs old. We recently ran the Self Clean mode, and it seems like it has malfunctioned...


Hi,

Do you see any Error Message on the Display?

If not, then it should not be a Concern. More often this could be Thermal Fuse on the Back of the Unit ( On Most Models ) will stop the Broil and Bake from Turning ON. You would just start a bake cycle and the temperature will sit at 100 and something degrees and never raise.appliance.

Let me know, once you check the same.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

Easy off ate all enamel off interior of oven


First off i must say that in your owners manuel it clearly states to not use any cleaning products inside the oven..

Second if the cleaner is now completely cleaned off then when put into the bake cycle it could possibly turn the cleaner into a toxic gas. I would not use the oven i would replace it.

Third having the enamel chip off is not a safety concern. it is merely cosmetic. however refer back to number 2.

Self-cleaning gas oven


Door lock motor has probably failed.....Self clean on many
ovens can be a self destruct mode. Door latch motors, sensor
probes and even the electronic controls can be destroyed by
this operation. On many freestanding stoves the lock motor is located in the right rear (looking from the front) with a long rod connected to the lock. remove the motor and unhook the rod from the motor cam. Sometimes bending a coat hangar into a hook and sliding from the right side into the lock you can unlock the door.
