Quick check — and when it's not DIY
The one self-check that's actually worth your time: compare the reading against a separate thermometer placed in the same spot for an hour. Beyond that, if the setting's right and it still misreads, the sensor or board needs testing with a meter, and a wrong guess here means paying for a part that wasn't the problem.
