DeLonghi EDB 475 ST Bottom oven not working. Clock is on, and fan is working, but no heat. Upper oven OK and working correctly.

SOURCE: GE Wall Oven - No heat (broil or bake)

On appliances like this only the heating elements use 220 volts. things like the clock, fan, etc use 110 volts. That is why some things work and other do not. Start at the breaker, sometimes a double pole breaker will have 1 side tripped, but will look perfectly fine. switch the breaker all the way to off then re-set. If nothing changes follow the power to the appliance remove the panel and look for some fuses, check to see if any are blown. Also sometimes the microwave will have a separate power source even though its built in to the same appliance. So that's not always a good symptom to follow.

Yes it will need a new element, if the fan runs and temperature light comes on then the element is gone.

If youhave a ELECTROLUX electric Cooker or Fan Ovenwhich is not heating it could be one of the following problems.

1, If the fan motor in theback of the oven is going round and the temperature light is on (normallylittle red light), but there is no heat then you will probably need a new ovenelement, these are generally very easy to fit and readily available from our websitethese can be tested with a electric meter.
To gain access to the ELECTROLUX element you willhave to remove the back plate from inside the oven. Once removed you will seethe fan and element, if you look closely at the element you willprobably see a small hole burnt in it where it has blown. Sometimes howeverthere is no evidence of a fault but the element is opencircuit i.e. broken inside the element casing, either way it will needreplacing. Some elements will are fixed from inside the oven and some are heldin place by nuts from the rear of the machine.

2, If your ELECTROLUXfan oven is getting warm but takes a very long time to cook or is burning thefood more on one side than the other, then you need to check if your oven fan motor isworking you will see the blade turning fast if it is ok. if the element isheating but the fan motor is notblowing the heat into the oven then you need To replace the oven fan motor is alittle more expensive and a bit more involved.
3. If you have the opposite problem i.e. your ovenis over heating and burning everything then you will need to replace your ELECTROLUXoven thermostat

4, A quite common and easily overlooked answer isif your ELECTROLUX oven is not working at all i.e. noheat and no fan then the chances are that someone has put the oven timer into AUTOmode, simply put oven back to MANUAL mode and all should be working again.

Hi,
If your electric oven is not heating then you probably have a bad heating element in your oven. This is not that hard to fix yourself...
