Why your Williams Refrigeration walk-in freezer is thermostat issue
Here's how thermostat issue typically presents on a Williams Refrigeration walk-in freezer: temperature inaccurate, cycling abnormally. Bad thermostat or temperature sensor. The usual culprit is a bad control board. Left unaddressed, food or stock can spoil within hours.
Most likely causes
- A bad control board

Quick check — and when it's not DIY
One thing you can rule out on your own: 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.
