An oven usually fails to reach the correct temperature due to a failing heating element, a defective temperature sensor, or calibration issues. In gas models, a weak igniter is often to blame. The solution often requires replacing a worn part or simply recalibrating the system.
If your oven isn't getting hot enough, the most likely culprits are a burned-out heating element, a weak gas igniter, a faulty temperature sensor, or a tripped circuit breaker. Always turn off the power or unplug the oven before attempting any inspection.
Replacing an oven heating element typically costs between $𝟏𝟓𝟎 and $𝟒𝟎𝟎 for parts and professional labor, with an average of about $𝟐𝟕𝟓. If you are comfortable doing a simple DIY repair, you can usually purchase the replacement element online or at a local hardware store for just $𝟐𝟎 to $𝟏𝟎𝟎.
Should I Repair or Replace my Oven? Oven repair costs range from $150 to $400, making repairs more affordable than replacement when your oven needs simple fixes or parts. You should replace your oven when repair costs exceed 50% of a new unit's value, especially if your appliance is over 15 years old.
If your oven is baking unevenly, burning your food, or taking too long, verify the issue by hanging a reliable Oven Thermometer in the center of the oven. Let it preheat for at least 30–40 minutes to measure the actual temperature, then either calibrate your settings or troubleshoot common part failures.
Replacing an oven temperature sensor costs between $𝟏𝟎𝟎 and $𝟐𝟓𝟎 on average. This total breaks down into $𝟐𝟎 to $𝟓𝟎 for the replacement part and $𝟖𝟎 to $𝟐𝟎𝟎 for professional labor. If you tackle this as a DIY project, you will only pay for the part.
To fix an oven that cooks unevenly, first verify the temperature and clean the cavity. Place an Oven Thermometer inside and preheat to 350°F. If the reading is off, adjust your oven's calibration. Remove foil liners that block airflow and perform a deep clean.
The average oven lasts between 13 to 15 years, though models with fewer complex electronic parts can last up to 20 years. Lifespan heavily depends on the type of appliance, brand quality, and how well it is maintained.
The Cost to Fix an Oven
Angi's reported that oven repair costs average around $350 as of 2022. However, the price varies based on the oven type and the part that needs repairing. Repairs on the lower end include fixing the thermostat, door switch, and gas valve.
You should start looking for a new oven if it requires frequent, costly repairs (the "50% rule" dictates replacing if a repair costs more than half the price of a new unit), shows signs of internal rusting, fails to reach or maintain temperatures consistently, or emits gas smells or strange odors.
You could be looking at a faulty oven heating element. However, there's no need to panic – this is a simple, straightforward repair that you can complete yourself, with no need for a professional. In this article, we will explain how to change the oven heating element and how to tell if it's broken in the first place.
Replacing an oven thermal fuse costs between $10 and $30 for the part itself. If you hire a professional appliance technician, expect the total cost to range from $100 to $350 for parts and labor. The exact price depends heavily on your oven's make, model, and the accessibility of the fuse.
To tell if your oven's heating element is bad, first unplug the oven and do a visual inspection for physical damage like blistering, burn marks, or cracks. Next, disconnect the element and use a multimeter to check it for continuity and proper resistance (which should read between 101010 and 404040 ohms).
Check the heating element
An oven that isn't heating properly may have a damaged heating element that needs to be repaired or replaced. If your oven has any exposed bake or broil elements, check for visible breaks or blisters.
A blown oven thermal fuse is a built-in safety mechanism designed to cut power if the appliance overheats. The most common symptoms include an oven that fails to heat up, a completely dead display console, or an oven that shuts off mid-cycle and won't turn back on.
Here are the tell tale signs that your oven's thermostat needs repair or replacement:
About 8–12 years old: It depends on the specific issue, overall condition, and the cost of the repair. About 12–15+ years old: Replacement often makes more sense, especially if repairs are stacking up or performance is inconsistent.
Common oven problems range from simple power issues to malfunctioning heating elements. Troubleshooting specific components like bake elements, igniters, and temperature sensors typically resolves most heating and cooking inconsistencies.
4 Common Electric Range Issues: Troubleshooting Tips
If your oven isn't getting hot enough, the most likely culprits are a burned-out heating element, a weak gas igniter, a faulty temperature sensor, or a tripped circuit breaker. Always turn off the power or unplug the oven before attempting any inspection.
Replacing a heating element is a common fix that usually costs between $150 and $400, depending on the make and model of your oven. Electric ovens tend to be on the lower end of the spectrum, while more advanced or high-end models may cost more. A faulty thermostat is often cheaper to fix than other components.
An oven temperature sensor regulates internal heat by sending resistance readings to the control board. Common symptoms of a failing sensor include wildly inaccurate temperatures, food burning on one side and raw on the other, error codes (like F3 or F5), and excessively long preheat times.
Changing a temperature sensor is generally an easy, beginner-friendly repair. For basic sensors—like car coolant or ambient air sensors—it requires basic hand tools, costs under $30, and takes about 20–40 minutes. Some hidden sensors (like AC evaporator sensors) can take a couple of hours.
To check if a temperature sensor is working:
Observe response to temperature changes. Check output signal using a multimeter. Perform a simple ice water or boiling water test. Inspect for physical damage or corrosion.
