Preheating an oven is necessary when preparing certain meals, especially baking.
Knowing how long it would take to preheat an oven to a specific temperature can help you plan your cooking.
To avoid undercooking or overcooking your meals. However, not all ovens are the same, and their heating time frames differ.
This article answers how long it takes to preheat different oven types to 425 degrees Fahrenheit.
15 to 20 minutes is the average time it takes for a convection oven to preheat up to 425 degrees Fahrenheit. Some ovens preheat faster than others due to their size and type. Electric ovens take 20-25 minutes to preheat up to 425 degrees Fahrenheit.
How Long Does Whirlpool Oven Take To Preheat To 425?
It takes approximately 15-18 minutes for a Whirlpool oven to preheat to 425 degrees Fahrenheit, with a 5 minutes increase per every 100 degrees over 350 degrees Fahrenheit.
However, the time frame still depends on the type and size of the Whirlpool oven.
To be completely certain, refer to your Whirlpool oven’s manual guide to verify the exact preheating time frames.
The preheating time frames for Whirlpool ovens are as follows;
#1. 250 To 300 Degrees Fahrenheit
This temperature is the lowest, hence will take the shortest time frame.
It takes about 8 to 10 minutes to preheat the oven to temperatures between 250 and 300 degrees Fahrenheit in whirlpool ovens.
#2. 300 To 350 Degrees Fahrenheit
This temperature range is within the medium preheating temperature level in Whirlpool ovens.
It takes roughly 10 to 15 minutes to preheat the oven to temperatures between 300 and 350 degrees Fahrenheit.
#3. 350 To 400 Degrees Fahrenheit
This temperature range is within the high preheating temperature level in Whirlpool ovens.
It takes 15 to 20 minutes to preheat the oven to temperatures between 350 and 400 degrees Fahrenheit.
#4. 400 To 450 Degrees Fahrenheit
This temperature range is the highest preheating temperature level in Whirlpool ovens. The time frame varies according to the type and size of the oven.
However, it takes about 20 to 25 minutes to preheat the oven to temperatures between 400 and 450 degrees Fahrenheit.
Most ovens come with different instructions on how to operate them. The instructions on preheating an oven for one brand may not be the same for another.
Therefore, the following steps below are specifically for preheating a Whirlpool oven:
#1. Step 1:
Clean the oven racks before placing the food. Dirty racks can affect the preheating time.
#2. Step 2:
Close the oven door and keep it closed throughout the preheating process. Do not open the door at intervals.
#3. Step 3:
Consult the oven’s owner instruction manual to verify and confirm the settings for preheating the oven. After this, set the timer and close the oven.
#4. Step 4:
Wait until the time frame elapses, open the oven and place the food inside.
If you have trouble operating your Whirlpool oven or find something confusing in the owner’s manual, you can contact Whirlpool’s customer care support here.
Below is a table of some of the best convection ovens with the shortest preheating time frames:

How Long To Preheat Gas Oven To 425?
It takes a gas oven between 14 and 16 minutes to preheat to 425 degrees Fahrenheit.
Generally, gas ovens take longer to preheat than Convection ovens but are faster than Electric ovens.
Below are the preheating time frames for various temperature levels in Gas ovens:
#1. At 350 Degrees Fahrenheit
At 350 degrees Fahrenheit, the lowest preheating level, it takes gas ovens between 9 to 10 minutes to preheat to this temperature. It takes an Electric oven 11 to 13 minutes.
#2. At 375 Degrees Fahrenheit
It takes gas ovens between 10 to 12 minutes to preheat up to the temperature level. Doing the same in an electric oven will take roughly 15 to 16 minutes.
#3. At 400 Degrees Fahrenheit
Gas ovens take 12 to 13 minutes to preheat up to 400 degrees Fahrenheit. Electric ovens take between 16 to 18 minutes.
#4. At 425 Degrees Fahrenheit
It takes a gas oven between 14 and 16 minutes to preheat up to 425 degrees Fahrenheit. An electric oven takes up to 20 minutes.
#5. At 450 Degrees Fahrenheit
450 degrees Fahrenheit is one of the highest preheating temperature levels you can preheat your oven.
It takes a gas oven 17 to 19 minutes to get to this temperature level, while an electric oven takes 22 to 25 minutes to do the same.
How Long Does It Take to Preheat an Oven Toaster?
It takes an average oven toaster 5 to 7 minutes to preheat to 450 degrees Fahrenheit. Oven toasters are much smaller than traditional cooking ovens, so they preheat faster.
Usually, it takes smaller ovens even less time to preheat up to 450 degrees Fahrenheit.
The size of the toaster oven is not what solely determines its preheating speed. The oven’s power rating capacity is also a major contributing factor.
So if you are thinking of purchasing a toaster oven, make your decision based on these two factors.
It is important to note that toaster ovens might draw less energy and have faster preheating time frames, but they are not as wide as traditional ovens.
You can consult your owner’s manual for more information concerning your particular toaster oven’s preheating capacity.
Why Does Oven Preheat Take So Long?
The preheating speed of your oven depends on its size, type, and power rating capacity. Smaller ovens with a good power rating capacity will preheat faster than traditional ones.
However, if your particular oven takes too long to preheat, it might be faulty. It may be that the oven igniter is damaged or the thermostat is malfunctioning.
If this is the case, inform a technician to replace or repair the parts immediately. If you’re using a gas oven, the problem could be a blockage in the gas supply feeding the oven.
For an electric oven, inspect the heating component or have a professional look at it thoroughly.
Normal functioning ovens don’t preheat for longer periods than they should; if they do, then they are probably faulty.
How Do You Know When Your Oven Is Properly Preheated?
Below are a few steps to test if your oven is preheating properly.
- Attach an oven thermometer to the oven and preheat to at least 350 degrees Fahrenheit.
- Keep the oven on for at least 15 more minutes, then take the temperature reading from the thermometer.
- Correlate the reading on the thermometer with the one on the oven and the time duration.
- If you notice the measurements don’t add up, then something could be wrong with your oven.
- Continue this process for an hour and compare the readings after every trial.
Summary
It takes 15 to 20 minutes to preheat up to 425 degrees Fahrenheit. This time frame, however, varies according to different oven types and sizes.
Toaster ovens preheat faster than traditional ovens but are smaller. If you notice your oven takes too long to preheat, have a professional look at it.
