What to do if Lytron LCS20 unit does not maintain temperature?

  Susan BurgessAug 3, 2025
  If your Lytron Freezer unit isn't maintaining temperature or the light on the front panel is on, the facility water flow rate might be too low. Ensure the facility water flow rate is set to a minimum of 7.5 GPM. Also, verify that the facility water temperature doesn't exceed 80° F (27° C). Check the water level in the reservoir and fill it to the proper level. If the problem persists, inspect for water leaks inside the front panel. If all of that is correct, the Electronic Controller, the Mixing Valve Assembly, or the Temperature Sensor might be faulty.
