Quick check — and when it's not DIY
Before you call anyone, 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. Once you've ruled that out, a sensor that's confirmed inaccurate has to be replaced and recalibrated against the control board — guessing which part is at fault wastes a parts order.
