Why your Foster Refrigerator walk-in cooler is thermostat issue
On a Foster Refrigerator walk-in cooler, thermostat issue usually announces itself like this: temperature inaccurate, cycling abnormally. Bad thermostat or temperature sensor. More often than not it traces back to stuck thermostat contacts. 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: confirm the temperature setting itself, and give the unit 24 hours after any adjustment before assuming it's broken. When that isn't the fix, 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.
