Retro fit cooker fan

[robertager1962]

We have a Nelson Spinflow cooker and as liveaboards, use this constantly. An excellent cooker it does suffer from the age old problem of these types of ovens in that everything burns at the top and doesn't cook at the bottom.
A.simple solution would be a fan.
Does anyone know of (or heard of a retro fit cooker fan)
I have trawled Google but to no avail.

If it is gas, I suspect that a fan will upset the flame. I'm not aware of any gas oven having a fan but stand to be corrected.

I do have the same problem with my gas oven on board and just rotate the items in it as required.

The top oven of my Electrolux gas cooker (there's an oxymoron) certainly has a fan. Strangely the larger, lower oven does not.

Afraid I cannot help with the OPs question.
