Why your Foster Refrigerator commercial freezer is thermostat issue
On a Foster Refrigerator commercial freezer, thermostat issue usually announces itself like this: temperature inaccurate, cycling abnormally. Bad thermostat or temperature sensor. On this platform it's most often wiring fault to the sensor. Left unaddressed, food or stock can spoil within hours.
Most likely causes
- A miscalibrated thermostat

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. 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.
