What Causes An Electric Oven To Heat Slowly?

Electric ovens are very efficient cooking appliances, but they take some time to heat up to cooking temperatures. But why would an electric oven work slowly and take too long to heat?
An electric oven model will heat up slower than others if it has hidden heating elements. For example, suppose your oven takes far too long to heat up. In that case, it’s because of leaking hot air, power supply problems, worn-out heating elements, or a faulty main control board.
Keep reading to discover why your electric oven is heating too slowly and what you can do to solve the problem.
Before assuming that your oven is heating too slowly, it’s crucial to understand what’s expected in electric oven heating times.
For starters, most electric ovens on the market heat up faster than gas models. However, the exact heating times for those ovens will depend on what model and brand you own.
The unique design of each model affects how it transfers heat from the element to the rest of the compartment.
Still, here are some average heating times that you can expect from electric ovens:
- To reach 350 degrees Fahrenheit: 15 minutes.
- To reach 400 degrees Fahrenheit: 17 minutes.
- To reach 450 degrees Fahrenheit: 22 minutes.
You can also check your oven’s user manual to find information about how fast the unit heats up to cooking temperature.
Based on those numbers, you can get a very accurate sense of whether or not your oven is taking too long to heat up.

Before troubleshooting your electric oven, always remember to take precautionary steps. Doing so will prevent you from suffering injuries like burns or electrocution.
So, before you inspect your oven, remember to:
- Disconnect the oven from its power supply or shut off its dedicated circuit breaker.
- Give the oven at least 45 minutes to cool down completely.
- Wear hand protection like oven mitts to protect your hands.
- Avoid touching metal and glass parts of your oven, as they hold a lot of heat.
Lastly, keep your oven user manual nearby for easy reference. Now, you’re ready to troubleshoot your slowly-heating electric oven!

Here are 5 top reasons why your electric oven is heating so slowly.
#1 Hidden Heating Elements
Not all electric ovens are made the same, even by the same manufacturer. Those different designs can have a significant difference in how fast they heat up.
For example, if you find that your new electric oven takes longer to heat up than the old one, take a look at its heating elements.
Many electric ovens conceal or hide their heating elements underneath the bottom panel instead of leaving them exposed. While that design makes the oven look neater inside, it also delays the heating process.
Simply put, a heating element that’s hidden away will not have optimal airflow. So, it’ll end up heating the oven’s floor before that heat enters the compartment to cook your food.
In these ovens, slow heating isn’t a sign of a problem. Instead, it’s just a side-effect of the oven’s design. So, if you’re shopping for an oven that heats up faster, choose a model with exposed heating elements.
