What Can Make Oven Temperature Off by 50 Degrees?

There are a few reasons why your oven could be 50 degrees off in temperature.

Let us reviews some of the more common reasons.

1. The Oven is Perfectly Functional

Oven Temperature Off by 50 Degrees
Sometimes an oven can get off by some degrees from time to time and return back to normal.

Most ovens usually have threshold that keeps it from dropping too low or rising too high. Usually, ovens don’t maintain the same temperature throughout. If you have set your oven to 350°. Your oven might likely rise up to 400° before it begins to drop.

It might also drop till about 300° before it begins to rise again. The means that your oven rotates between a lower and a higher temperature.

The average is usually what you have set your oven to.  So an oven temperature being off by 25°-50° might be perfectly natural for the oven.

You will likely discover that ovens do not give a perfect temperature to correlate with what has been set, except you take measures towards regulating the oven temperature as well as exercise some patience to ensure that the temperature is perfectly suited for your meal.

While your oven temperature might not be due to any underlying problem, there are other causes that might result in your oven temperature dropping or rising beyond what you have set.

To Fix This Problem

To fix this issue, you need to regulate the temperature controls based on the temperature in the oven.

To know the oven temperature, ensure that you have an oven thermometer at home.

Preheat your oven at least 20 minutes before use

Check the oven temperature with a thermometer to see how off it is.

If it is off by less than 50° it shouldn’t be much of a problem, you can just leave it as it is

If it is off by more than 100°, you might need to call a technician

If it is between 50-100°, you might need to check your oven thermostat sensor. It is usually located at the back of the oven. If you realize that it is not properly balanced or its leaning on the oven wall, it might be one of the causes.

Check if this problem can be fixed by tightening the screws holding the sensor in place.

Once this is done, check the oven temperature again and compare it to the display to see if it is still inaccurate

Take out the temperature controls, loosen the screws and adjust the numbers. Once you rotate, depending on your oven measurement and the direction you rotate in, the numbers will be adjusted. Test the oven again

If you feel something is wrong at this point, you might have to use the services of a technician

2. Calibration Issue

Most oven are required to be properly calibrated to function optimally.

In fact, when you make a new purchase, there are likely instructions in the oven manual that will help you get the best out of your oven calibration

To Fix This Problem

To fix, hold down the oven calibration button. Once the temperature comes on and the oven is preheated, compare it to that of your oven and adjust accordingly. If it is on 0°, you might need to wait for about 30 minutes to be sure of the right temperature to calibrate.

If your oven is an old one or you can’t seem to figure out how to calibrate, you might need the services of a technician.

If you’re sure that your oven sensor is not bad or the calibration not faulty. The heating element might be broken or faulty.

To check if this is the case,

Preheat your oven for at about 30 minutes and look through your oven door to see if your oven heating element is very hot. It glows red hot when it is at the peak of its function.

If either of the two are misaligned, lose, or broken, they may not be positioned at the right temperature setting.

To Fix This Problem

Look for visible damages on the knob selector or on the knob shaft.

Furthermore, if you face any difficulty turning the knob or if you feel the knob is loose, then that could be the culprit.
