Possible Causes

Low water level in reservoir, partially clogged water filter (if equipped), misadjusted ice thickness sensor, scale buildup on evaporator

How to Fix / Troubleshooting

Safety First: Unplug the unit before cleaning internal components.

Steps to improve ice thickness:

  • Check water level: Ensure the reservoir fills to the correct level. Clean the water level float and verify it moves freely.
  • Clean evaporator: Use a mixture of warm water and white vinegar to remove mineral deposits from the evaporator plate.
  • Adjust thickness sensor: If your Koldfront model has an adjustable ice thickness sensor, follow the manual to slightly increase the thickness setting.
  • Replace filter (if present): If the unit has an inline water filter, replace it to restore proper flow.
