Quick check — and when it's not DIY
There's one thing worth checking before you book anyone: confirm the temperature setting itself, and give the unit 24 hours after any adjustment before assuming it's broken. Also, 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.
