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. On this platform it's most often a miscalibrated thermostat. Left unaddressed, food or stock can spoil within hours.

Quick check — and when it's not DIY
Before you call anyone, confirm the temperature setting itself, and give the unit 24 hours after any adjustment before assuming it's broken. Also, compare the reading against a separate thermometer placed in the same spot for an hour. If none of that changes anything, if the setting's right and it still misreads, the sensor or board needs testing with a meter, and a wrong guess here means paying for a part that wasn't the problem.
