How to Test & Recalibrate a Thermo Kool Walk-In Cooler or Freezer Dial Thermostat 

  • Step 1. Test the temperature readings on your dial thermostat – Place a thermometer within your Thermo-Kool walk-in cooler or freezer.
    • Note: You’ll want to wait about five minutes for the thermometer to record the temperature.
  • Step 2. Compare the thermometer’s reading to the dial thermostat – If the two results differ, then it’s time to recalibrate your Thermo Kool walk-in cooler or freezer dial thermostat. 
  • Step 3. Unscrew the dial thermostat – Take a flathead screwdriver and remove the three screws attaching the thermostat cover to the cooler or freezer’s exterior.
  • Step 4. Place an index finger on the needle – To prevent the needle from moving, place your index finger at its widest end close to the center. 
  • Step 5. Recalibrate your thermostat – Referencing your thermometer, turn the screwdriver clockwise to increase the temperature or counterclockwise to decrease the temperature.
  • Step 6. Refasten the screws – Don’t forget to return the three screws to their rightful places. Good work, you’ve now recalibrated the dial thermostat on your Thermo-Kool walk-in cooler or freezer!
