Why your Foster Refrigerator walk-in freezer is thermostat issue
Catching thermostat issue early on a Foster Refrigerator walk-in freezer is usually straightforward: temperature inaccurate, cycling abnormally. Bad thermostat or temperature sensor. Nine times out of ten it comes down to failed temperature sensor. Left unaddressed, food or stock can spoil within hours.

Quick check — and when it's not DIY
Start here — it costs nothing and rules out the easy cause: compare the reading against a separate thermometer placed in the same spot for an hour. Beyond that, 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.
