Why your Summit Commercial walk-in cooler is thermostat issue
On a Summit Commercial walk-in cooler, thermostat issue usually announces itself like this: temperature inaccurate, cycling abnormally. Bad thermostat or temperature sensor. The usual culprit is 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. Also, 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.
