Question about Bosch HBN 7052 GB Stainless Steel Electric Double Oven

1 Answer

MAIN OVEN DOESNT WORK

I have HBN 7050GB Double oven. Everything works fine except lower oven in which the element has blown (definitely open circuit). Replaced element, however still doesnt work. Element resistance is 36 ohms so fine. However 240v not getting to connectors when powered on. Is there an internal fuse somewhere? not sure where to go with this

    but upper oven would also be off if oven switch contacts blew right?

  • Anonymous May 12, 2009

    Hi I have the same problem, have had 6 new elements in 3 years and blew again last night. Very dissapointed as I have all Bosch appliances to match. I am buying a new oven now as it has cost me £800 to buy and a further £300 on callouts/ elements. Fitter told me it is a know problem with this type of element but Bosch haven't done anything about it.

Common heating faults with Bosch HBN 430560B / 430520B 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.

Most likely the heater element has burnt out. This is accessible by removing the panel in the back of the oven.

Bottom oven does not heat up fan works


The element is usually located at the rear of the oven compartment,behind a removeable cover, this is also where the fan is located.
