10 years of fridge repairs and I just learned I've been putting thermistors in backward

Was out on a Whirlpool side by side last Wednesday in Nashville, customer said freezer was too warm. I swapped the thermistor like I always do, checked temps, still reading weird. My helper who's been with me 3 months goes 'uh, isn't that sensor supposed to face the coil, not the wall?' I looked at my service manual and sure enough I've had them flipped for a decade. How many times do you think I misdiagnosed something because of a dumb orientation mistake?

Oof, that's a costly decade of backwards thermistors.

@sandra146 hit it right on the head. Costly is an understatement. You probably sent a lot of people home with wrong parts or unnecessary visits. I once spent a whole afternoon chasing a ghost in a Kenmore freezer and it turned out I had the thermistor wire pinched behind a bracket. 10 years is a whole career oopsie. At least you caught it before retirement.
