Oven temp gets hotter than control indicates.

What make and model?

Sounds like you need a new oven thermostat or get an oven thermometer and by experimentation draw up a new heating range for the oven dial.

If you are monitoring the oven temperature with an analog style thermometer you may actually be ok, but seeing the thermometers slow reaction time.
Some newer ovens actually do pre-heat beep prior to reaching temp in an effort to conserve eelectricity.
A good home test is to try your oven at several different temps to see if there is any variation in internal temperature. Try it one day on 300, the next at 375 and another day at 450. Give your analog style thermometer time to catch up (usually just about 15 min) and leave it on for a half an hour to see if the temp maintains.
Also Beware of aluminum foil AND THE NEW OVEN LINER MATS as they can alter oven performance bay absorbing and blocking the ovens natural heat radiation and convection air flow currents that happen in all ovens, not just convection models.
Another interesting fact is that older ovens used a thermostat in them that operated much like your thermometer and was very slow to react making the oven typically about 100 degrees hotter than where the customer set it. This was just a fact of life before the advent of electronic temperature management and became noticeable when people began trying to bake older "hand me down" recipes in the newer ovens with less than stellar results.
You can mimic the older oven performance by preheating the oven about a hundred degrees higher than called for and after it reaches temp, re-set it to the correct temperature and put the items in right away.
If you find your temperatures fluctuating ask your servicer to replace first the temp sensor and as a last resort the control board as this part is usually pretty expensive.
Good Luck with this!

It will be the sensor inside the oven compartment that is causing the problem.
A new sensor should cure the prob, certainley cheaoer than buying a new oven.
Hope my advice helps you.

On most oven temperture controls, if you pull the knob off there is an adjustment screw down in the shaft turn counterclock wise?? to lower setting. Good luck

If you remove the dial you should find an adjustment behind the dial to match it to the temperature.

Use a 'oven thermometer' in the oven and determine the 'actual temperature' in the oven. Your knob setting is off (not calibrated) and the oven is hotter than the control knob setting.

There is no real way to calibrate the thermostat. Most ovens have the same problem. By lowering the setting slightly will help get a closer temperature. Sometimes similar thermostats are substituted and may not be exactly the same as the original that came with your oven. Hope my trying to answer your question was helpful, Thanks, Sea breeze

click the link  Oven temp sensors sense the temperature is the oven cavity and the temp sensor changes resistance, this change in ohm resistance tells the oven control what temperature the oven cavity at and tells the control to shut off the element or turn it back on. The most common temp sensors used today ( *not all ) are approx 1000-1100 ohm resistance at room temperature ( 70�F )
Some ohm readings and there temperature:
Degrees F    -   Resistance
            100 - 1143 ohms
             200 - 1350 ohms
             300 - 1553 ohms
             350 - 1654 ohms
             400 - 1753 ohms
            500 - 1949 ohms

Check the temperature select knob. On the inside of the knob there should be an adjuster.

The temperature probe may be the faulty component since this is an integrated machine.
