SOURCE: Bosch oven won't pre-heat/heat with door closed

Some oven has a door sensor, which prevents heating when door is open, evidently this is faulty, you need a service manual to identify and replace the part, If I find something I will post here.

SOURCE: Bosch HBL 645 oven door won't close all the way

I am afraid that the door hinges are non adjustable, and the only solution is to replace them as a pair.
There should be some kind of latch mechanism at the end of the hinge
where it is fastened to the door to compress the hinge to enable you to remove them.
Hope this helps.

The oven is secure undercounter by four screws which you can see when you open the door and are located on the body frame at the left and right.
After that you can pull it out completely so you can remove the top panel cover at where you can reach for the control panel.
Here we have a link with the parts diagrams you can see the other diagrams total 5 by selecting from the left.
We also one video on how to replace the element with a similar oven which however will give you an idea how is your oven and how to remove top internal cover.

Common heating faults with Bosch HBL 442 / HBL 446 single oven


For all Free appliance repair videos visit our VIDEO TUTORIALS 1, If the Bosch fan motor in the back of the oven is going round and the temperature light is on (normally little red light), but there is no heat then you will probably need a new oven element, these are generally very easy to fit and readily available from our website these can be tested with a electric meter.
To gain access to the BOSCH element you will have to remove the back plate from inside the oven. Once removed you will see the fan and element, if you look closely at the element you will probably see a small hole burnt in it where it has blown. Sometimes however there is no evidence of a fault but the element is open circuit ie: broken inside the element casing, either way it will need replacing. Some elements will are fixed from inside the oven and some are held in place by nuts from the rear of the machine.
2, If your BOSCH fan oven is getting warm but takes a very long time to cook or is burning the food more on one side than the other, then you need to check if your oven fan motor is working you will see the blade turning fast if it is ok. if the element is heating but the fan motor is not blowing the heat into the oven then you need To replace the oven fan motor is a little more expensive and a bit more involved.
3. If you have the opposite problem ie: your oven is over heating and burning everything then you will need to replace your BOSCH oven thermostat
4, A quite common and easily overlooked answer is if your BOSCH oven is not working at all ie: no heat and no fan then the chances are that someone has put the oven timer into AUTO mode, simply put oven back to MANUAL mode and all should be working again.

Bosch Oven Door Problem - doesn't close at top


On our oven (Bosch Evolution 700 Series HGS7152UC), the problem was getting worse and worse. I found it is was worsening simply because the hinges had started to come loose. I removed the door as suggested above, and although there are no adjustment screws on this model I tightened the now-loose hinge mounting screws. For each hinge there are three screws altogether: two (phillips heads) on the bottom of the door and one (torx head) on the inside wall of the door. After tightening those screws it is a lot better, only leaks as much heat as it did when it was new which is tolerable. Still a bad design.
