Why your walk-in cooler is thermostat issue
A walk-in cooler that is thermostat issue tends to show the same signs, whatever the brand: temperature inaccurate, cycling abnormally. Bad thermostat or temperature sensor. Nine times out of ten it comes down to stuck thermostat contacts. Left unaddressed, food or stock can spoil within hours.
Most likely causes
- Failed temperature sensor
- Stuck thermostat contacts
- A bad control board
- A miscalibrated thermostat
- Wiring fault to the sensor
Quick check — and when it's not DIY
Worth checking yourself first: 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. Past that point, 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.
