What to Do If Your Oven Doesn't Heat Evenly?

The Problem

Baking can be frustrating when your oven doesn't heat evenly — one side of the cake is golden brown while the other is still raw. I had this exact issue with my own oven, and my first thought was that it was completely broken. But after reviewing the user manuals, I discovered that uneven heating is often caused by simple issues that can be corrected without professional help.

Common Reasons for Uneven Heating

1. Faulty heating elements – The top or bottom element may be partially burned out.
2. Blocked air circulation – Overcrowded trays or pans can stop heat from circulating properly.
3. Dirty oven interior – Grease and residue affect heat distribution.
4. Malfunctioning thermostat – Incorrect temperature readings cause uneven baking.
5. Improper rack position – Cooking on the wrong level changes how heat spreads.

Step-by-Step Troubleshooting

1. Test the Heating Elements

The user manuals explained how to visually check if both top and bottom elements glow red when the oven is on. If one doesn't, it may need replacement.

2. Improve Air Circulation

I had been placing multiple pans close together. After rearranging them and leaving space between trays, the oven started cooking more evenly.

3. Clean the Oven Interior

A layer of burnt grease had built up. Following the cleaning guidelines in the manuals, I removed it, and heat distribution improved.

4. Calibrate or Check the Thermostat

I used an oven thermometer and discovered the internal temperature was lower than the setting. Manuals showed how to adjust calibration, and afterward, the results were much better.

5. Adjust Rack Placement

I moved the baking tray to the center rack as recommended. This allowed more balanced airflow and consistent cooking.

My Experience

At first, I thought I would need a new oven. But after checking the user manuals and following simple steps — cleaning, adjusting rack placement, and improving airflow — I fixed the issue myself. The next cake baked perfectly, with even browning on all sides.
