Having an oven that doesn’t bake evenly can be incredibly frustrating. You carefully follow the recipe, preheat your oven, and put your culinary masterpiece in to bake, only to find that parts are undercooked while other sections are burned.

An oven that bakes unevenly can turn even the most experienced bakers into beginners again. But don’t despair. With a few troubleshooting tips, you can get your oven baking evenly again.

At Fix4U Repairs, we’ve seen all kinds of oven baking issues over our years of appliance repair. We know that an unevenly baking oven is one of the most common problems homeowners face.

In this article, we’ll walk you through the top reasons your oven isn’t baking evenly and provide solutions to get your oven working properly again. Read on to diagnose your uneven baking issue and learn how to fix it.

Common Causes of Uneven Baking

There are a few key culprits that typically cause ovens to bake unevenly:

Inaccurate Oven Temperature

The most common cause of uneven baking is an inaccurate oven temperature. If the oven temperature is higher or lower than what you’ve set it to, parts of your dish will be undercooked while other parts end up overdone.

You may notice this issue more severely when baking sensitive dishes that rely on precise temperatures, like cakes, cookies, and pastries.

An inaccurate oven temperature can be caused by:

  • Faulty oven thermostat or temperature sensor
  • Improperly calibrated oven
  • Failing heating element

To check if this is the issue, use an oven thermometer to see if the actual oven temperature matches the setting.

If it’s off, try recalibrating the oven and testing again. If it’s still inaccurate after recalibrating, your oven thermostat or heating element likely needs repair or replacement.

Malfunctioning Heating Element

Problems with the bake or broil heating elements themselves can also lead to uneven baking. If the elements have any cracks, frayed spots, or breaks, they won’t heat properly. This results in hot and cold spots in the oven.

Visually inspect the bake and broil elements to check for damage. Turn the oven on and see if the elements heat up evenly along their length when the oven is preheating.

If you notice any damage or inconsistent heating, the heating element will need to be replaced. This generally requires hiring an appliance repair technician.

Improperly Positioned Oven Racks

Believe it or not, improper oven rack placement can prevent your oven from baking evenly.

Most ovens are designed to bake best when racks are placed in the middle positions. If racks are placed too high or too low, air circulation and heat distribution in the oven will be affected.

Always check that oven racks are positioned correctly with at least a few inches between pans/dishes and the top and sides of the oven. Center racks in the middle slots.

Use oven rack guides if available on your model. Adjust rack positions if needed to optimize baking.


Loading too many pans or baking dishes into the oven at once can also impede air circulation, leading to uneven baking.

Be sure to leave at least 1-2 inches of space around all sides of baking dishes so air and heat can flow properly throughout the oven. Stagger pans across racks if needed.

Only bake on 1-2 racks at a time when possible. Remove unused racks while baking.

Poor Air Circulation

Along with overcrowding, poor air circulation in an oven can cause uneven baking. If your oven has hot and cold spots, it’s likely a circulation issue.

Check that oven vents aren’t blocked by pots, pans, foil, or anything else. Keep the oven door closed as much as possible while baking.

Use a small fan to improve air circulation if possible. Or improve circulation by rotating dishes mid-way through baking.

How to Troubleshoot an Oven That Bakes Unevenly

Now that you know what can cause uneven baking, it’s time to troubleshoot your oven. Follow these steps to properly diagnose and fix your uneven baking problem:

1. Test the Oven Temperature

The first step is checking if your oven temperature is accurate. Heat your oven to 350°F and place an oven thermometer inside.

Allow the oven to preheat completely, then check the thermometer. If the temperature doesn’t match the dial setting, your oven’s thermostat is off.

If it’s off by more than 25 degrees Fahrenheit, the issue likely requires professional repair of the thermostat or temperature sensor. You can try recalibrating first, but serious inaccuracies usually indicate a faulty part.

2. Inspect the Oven Heating Elements

Once you’ve checked the temperature accuracy, inspect the heating elements. Look at both the bake element at the bottom of the oven and the broil element at the top.

Check for:

  • Burnt, frayed, cracked sections
  • Glowing or dark spots when heated
  • Broken or detached wiring

If you see any damage, the heating element needs replacement. An oven heating element typically lasts 5-10 years before requiring replacement.

3. Check Oven Racks

Verify oven racks are positioned properly with a few inches of clearance on all sides. Move racks to the middle slots if needed.

Use oven rack guides if available to optimize rack positioning. Racks should be level once inserted.

If your oven racks are warped or damaged, replace them. Check that racks slide in and out smoothly.

4. Test Air Circulation

Circulation issues are harder to diagnose yourself, but you can do a quick test.

Place slices of white bread closely around the edges of two oven racks. Heat the oven to 350°F for 5 minutes.

Check the toast’s color – significant color variances indicate poor air circulation. Have a technician examine the fans and ventilation.

5. Adjust Your Bakeware Setup

Finally, adjust how you’re loading your oven to allow for proper air flow:

  • Only use 1-2 racks max for baking
  • Leave 2+ inches around bakeware
  • Stagger items on racks
  • Remove unused racks

Follow these guidelines to prevent overcrowding and optimize circulation.
