Quick check — and when it's not DIY
Start here — it costs nothing and rules out the easy cause: compare the reading against a separate thermometer placed in the same spot for an hour. Also, confirm the temperature setting itself, and give the unit 24 hours after any adjustment before assuming it's broken. Past that point, 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.
