I did a great pebkac. I got a new fridge so I used my IR heat gun to test temps. It was high, way to high. Got service guy out under warranty. I showed him the issue. Deadpanned he takes the IR heat gun out of my hands, moves it closer to the fridge and says “you’re too far away. It’s pickup up the air temp from outside the fridge.”. Sure enough it read perfect temps when it was closer.

Thankfully the door alarm speaker was faulty so it wasn’t a completely wasted trip.
