Quick check — and when it's not DIY
Before you call 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. Should that not clear it, 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.
