Is your lasagna burned on one side and undercooked on the other? Or maybe your cookies come out half-baked in some areas and crispy in others? An oven that doesn't heat evenly is more than just an inconvenience—it can ruin your meals and waste your time. If you’re constantly second-guessing your oven's temperature, it’s time to take action.

At thematrixsolutions, we specialize in diagnosing and repairing ovens that are underperforming. In this guide, we’ll cover the most common causes of uneven heating and give you practical tips on how to fix them—whether it's a DIY job or time to call the pros.

1. Faulty Bake or Broil Element (Electric Ovens)

The bake and broil functions of electric ovens produce heat from both the top and the bottom. If either of these elements is damaged or burned out, your oven will heat unevenly or not reach the desired temperature.

Signs of Trouble

• One part of the oven is hot while the other is cold
• Food burns on the top or bottom only

Solution

• Inspect both elements for visible damage, like cracks or blisters.
• If one isn’t glowing or is broken, it needs to be replaced.

Not sure how to replace it? Call thematrixsolutions, and our expert techs will handle it safely and quickly.

2. Malfunctioning Oven Temperature Sensor

The temperature sensor monitors the oven’s internal heat and signals the control board to adjust the elements accordingly. If the sensor is faulty, the oven may overheat or underheat in certain areas.

Symptoms

• Oven takes too long to preheat
• Food is undercooked or overcooked
• Inconsistent temperature readings

What to Do

• Check that the sensor isn’t touching the oven wall, which can throw off readings.
• If the sensor is off by more than 20°F, it should be replaced.

3. Broken Convection Fan (If Equipped)

Convection ovens circulate hot air for uniform cooking using an exhaust system and fan. If the fan stops working, hot air won’t move properly, leading to uneven temperatures.

Signs You Have a Fan Issue

• Uneven browning or baking
• Strange humming or no sound when fan should be running

Fix

• Listen for any odd noises, which could indicate a bad motor.
• Replace the fan motor or blade if it’s not working.

4. Improper Rack Placement or Overcrowding

Sometimes the way you use the oven is the problem, not the oven itself. Incorrect rack placement or overcrowding can block airflow and cause food to cook unevenly.

Common Mistakes

• Using the wrong rack level for the type of dish
• Overloading the oven with multiple trays

Tips to Fix It

• Use one rack at a time if possible.
• Leave space between trays and oven walls for airflow.

5. Calibrated Incorrectly

Oven temperature calibration can drift over time, meaning your oven might be 25°F too hot or too cold—even though it says it's preheated.

Test It

• Place an oven thermometer inside and compare it to the set temperature.
• Let the oven preheat for at least 20 minutes for an accurate reading.

How to Adjust

Some ovens allow manual calibration through the control panel. Others may require a technician to recalibrate or update the control board.

6. Dirty or Greasy Interior

A build-up of grease or food debris can block heat distribution and even absorb some of the oven's heat, resulting in uneven cooking.

What You Can Do

• Clean the oven regularly using a safe oven cleaner.
• Avoid letting spills sit too long—burnt-on food affects heat flow.
• Clean the fan (if your oven has one) to ensure proper air circulation.
