If you continue cooking the cheesecake until the center is firm and doesn’t jiggle it will be baked for too long.
Some bakers prefer to let the cheesecake cool in the oven. Turn off the heat and let the cake sit in the oven with the door cracked about 1 inch (2. 5 cm) for 1 hour. At that point, take the pan out of the oven, remove the springform pan from the water bath (if applicable), and let the cheesecake cool completely before taking it out of the springform pan.

You should occasionally calibrate your thermometer to be sure it gives an accurate reading. To do so, fill a small pan with water and bring it to a rolling boil. Take the water’s temperature—it should be 212 °F (100 °C). [10] X Research source Turn the hex bolt at the bottom of an analog thermometer to calibrate the temperature if it is incorrect. Consult the manufacturer’s directions to calibrate a digital thermometer. [11] X Research source
Keep in mind that sticking a thermometer in the cheesecake may cause it to crack, so try to only test the temperature once, rather than multiple times. If you must test it more than once, stick the thermometer in the same hole you used the first time to minimize cracking. [13] X Research source
