Bottom oven is directly linked to the clock, If the clock is on but not set ie 0:00 or 12:00 flashing it won't work, set the time (doesn't have to be right, just not flashing) try oven again. If this is not the problem please contact me again and we'll look further. Cheers

one element, but you will need to open the rear of the oven to access and remove the 3 screws holding the fan and with a little bit of push and shoving you will be able to remove the screw behind the fan be careful the screw does not get stuck behind the fan. Putting the new element in will require bending the securing bracket slightly but don't worry it will straighten when you replace the screw behind the fan; which is easier to replace than when you remove it

The nut is a left hand thread, so unscrew it clockwise to release it, hold fan blade as you are doing this. Tighten anti- clockwise.
Plz rate my solution.
Thanks.

You need to remove the element from inside the oven cavity, but it is a bit of a fiddle. Once you have removed the screws at both ends of the element you need to remove the fan blade to access the centre fixing screw. Once all srcews are remove you have to twist the element and pull forward to remove the wires from the hole on the left, then remove the wires and refit to new element.

It should just pull off, try spraying some wd 40 onto the spindle, or apply some heat to the fan to expand it with a blow lamp or hot air dryer.

Hi there,

I'm figuring you've probably resolved this, since you posted in November (and I've just joined the site today). However, I thought I'd post a solution just in case anyone else surfs in and finds the same problem.

We have the same sort of oven. After the power has been off, the oven won't work until you set the time on the clock. I think it's because of all the automatic timer features.
On ours, you have to press the two buttons with arrows on at the same time as turning the clock dial to change the time.

Good luck.

More likely the heater element.. I hope this helps...

There could be a fault in the lower oven , or it could be overloading the circuit. add the watts of the two elements and divide by line voltage, this will give amps , now check the fuse rating amps , it must be higher than the oven. If that checks out ok the fault is in the oven.

If you are sure there is 220v going to unit, it most likely is element or click / control. If you have a ohms meter, you can test the element

I think there is an inline fuse for each oven/element.

it sounds to me that the fan is not working properly. as the oven gets older the fans become weaker and then doesn't blow air over the element at a rate that can the temp down enough..

See if the toc is open circuit , it is situated just above the heater connectors at the rear .
