Belling 865 fan oven help...

[phil0001]

Hi all,

Hoping someone winth knowledge of electric ovens may be able to help.

We have just moved into a house, where there is a freestanding 'Belling 865' dual fuel cooker (gas hobs, electric fan oven).

There is a selector dial so you can choose whether you want oven/fan oven/grill etc and a temperature dial.

When fan oven is selected it takes ages to heat up (waiting for yellow thermostat light to go out) - prob more than 45 mins if it ever heasts up fully, then when the door is opened it loses nearly all the heat.
When the normal oven (without fan) is used, it heats up as expected and retains the heat better.

The instuctions say it is using the same elements for these functions (top and bottom heating elements), so i am a little confused.

We also have a receipt left with the oven stating a new element was fitted in March, due to 'no heat'.


Any ideas as to what is happening?
We may get a new oven soon anyway so dont really want to spend much/anything on it!

Thanks in advance

If it works ok without the fan, then the elements are ok. It could be that when you use the selector to select fan, there is a bad contact/lose wire that is disconnecting one of the elements.
If you intend to replace the unit, why not just use the conventional oven.

thanks for the suggestion, i will just be using whatever i can get to work for now

FYI

so last night i quickly tried all of the selections and the results were as follows:

1-oven off- ok!
2-oven light on only- ok
3-fan on only- ok
4-top and bottom heating elements on- ok (heats up, wouldnt know if both elements are working though)
5-top and bottom heating elements and fan on- heats up very slowly as described above
6-bottom heating element and fan on- no heat, fan works though
7-rear heating element and fan on- appears to be ok, heats up and fan works
8-grill heating element on- ok
9-grill heating element and fan on- ok

from the descriptions it would seem it has a rear,top and bottom oven heating element, and a grill heating element (visable one)- this seem right?
I assume the rear element will be behind the fan cover at the back of the oven. But dont know where the top and bottom are, no other access panels inside the oven (apart from the fromt face that the door closes on to which has screws holding it on.)

Seems strange that the instuctions say that just top and bottom heating element come on for number 5 (they say this setting is 'traditional fan cooking'), not the 'rear' one.


Anyway, will try cooking with number 7, although they say this is best for cooking cakes - no chance!

Thanks all

The top element is usually the grill element as well and is visible.

The bottom element is underneath the bottom and is usually accessed by removing the front and rear covers and quite often a bottom plate (not always do you need to do all three but many ovens do)

You can test the bottom element usually by selecting the appropriate setting (if their is one for just the bottom element) leaving it running for a short while and seeing if the base of the cavity gets warm.

The top element is usually 2 elements in one mounting frame. If one fails you may still get heat but it will take longer to reach the higher temps if at all.

The fan oven element is mounted behind the rear plate and fits around the fan.

Some reasons for poor heating are fan failed or failing (not getting to correct speed)
Blocked vents in the rear plate.
One or more elements failed
Thermostats or regulator failed
Poor door seal
Poor door closing (hinges or door rollers wearing preventing the door shutting fully normally seen as a gap at the top)
