Enhance Heat Equality in Mini Oven

I'm dealing with an issue of uneven cooking in my mini combi oven due to troublesome heat distribution. Attempts have been made to confront this challenge by modifying the internal structure of the oven. Specifically, I've made adjustments to the air flow channels in an effort to improve heat coverage. Though this improved the problem, it has not been fully resolved. Ideally, I am seeking someone with prior appliance repair experience or knowledge of oven mechanics.

The ideal freelancer would chiefly possess the following skills and experience:

- Knowledge and understanding of heat processes within ovens
- Experience with mechanical or system modifications on home appliances
- Innovative and creative thinking for problem-solving
- Ability to effectively communicate the complicated processes involved

The overall project aim is to improve the heat distribution in my mini oven, eliminating the current uneven cooking issue. Your role will involve troubleshooting and delivering solutions based on the existing modifications of the air flow channels.

We are in the initial stages of developing our new Mini Combi Oven, and we are currently facing an issue with uneven heat distribution in our oven, particularly when baking egg tarts. Each layer of the oven seems to result in uneven heating, with the right side of the egg tarts consistently exhibiting a darker color. We are seeking the expertise of a professional on the Freelancer platform to address and rectify this internal uneven heating issue. The goal is to optimize the oven's performance and ensure uniform cooking results for our egg tarts.
