Why your Williams Refrigeration walk-in cooler is thermostat issue

Quick check — and when it's not DIY
There's one thing worth checking before you book anyone: compare the reading against a separate thermometer placed in the same spot for an hour. If that doesn't fix 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.
