Why is my Manitowoc Koolaire K not releasing ice?

  Patrick ThompsonAug 1, 2025
  If your Manitowoc Ice Maker isn't releasing ice properly or seems slow during harvest, several factors could be at play. First, the unit might be dirty, requiring a thorough cleaning and sanitization. Ensure the ice maker is level. For air-cooled models, verify the surrounding air temperature is at least 40°F (4°C). Finally, if you have a water-cooled model, a leaky water regulating valve in harvest mode could be the culprit, necessitating a replacement.

  If your Manitowoc Ice Maker isn't operating, several issues could be the cause. First, check if there's electrical power reaching the machine by replacing the fuse, resetting the breaker, turning on the main switch, or ensuring the power cord is properly plugged into the receptacle. Make sure the ice machine is turned on by placing the toggle switch in the ICE position to start ice making. Finally, ensure the curtain is in the closed position and can swing freely.

Why is the ice quality poor in my Manitowoc Ice Maker?

  If your Manitowoc Ice Maker is producing ice that is soft or not clear, it could be due to several reasons related to water quality. The incoming water quality might be poor, so you should contact a qualified service company to test it and recommend appropriate filters. The water filtration might be insufficient, so try replacing the filter. Also, the ice machine might be dirty, so cleaning and sanitizing it could help. If applicable, your water softener might be malfunctioning, so consider repairing it.

What to do if Manitowoc Koolaire K Ice Maker produces incomplete cubes?

  floreswilliamAug 13, 2025
  If your Manitowoc Ice Maker is producing shallow or incomplete cubes, or the ice fill pattern on the evaporator is incomplete, several factors could be responsible. The ice thickness float switch might be out of adjustment, requiring you to adjust it. The water trough level could be too high or too low, so check the water level and adjust as needed. Poor water filtration could be the issue, so replace the filter. The incoming water might be too hot, so connect the ice machine to a cold water supply. The incoming water pressure might be incorrect, so ensure it is within the range of 20-80 psi (137.9 - 551.5 kPa). Finally, the ice machine might not be level, so level it.

  If your Manitowoc Ice Maker stops and can only be restarted by turning it OFF and then ON, it indicates that the safety limit feature is stopping the ice machine. Please refer to 'Safety Limit Feature' on the next page.

Why won't my Manitowoc Koolaire K Ice Maker cycle into harvest mode?
- S
  saundersdouglasAug 22, 2025
  If your Manitowoc Ice Maker isn't cycling into harvest mode, it could be due to several reasons. The six-minute freeze time lock-in might not have expired yet, so wait for it to expire. The ice thickness float switch might be dirty, so clean and sanitize the ice machine. The ice thickness float switch wire might be disconnected, so connect the wire. The ice thickness float switch might be out of adjustment, so adjust it. Finally, if there is uneven ice fill (thin at top of evaporator), see 'Shallow or Incomplete Cubes' on the next page.

Why is the ice sheet thick in my Manitowoc Koolaire K?
- K
  Kathleen WrightAug 27, 2025
  If the ice sheet is too thick in your Manitowoc Ice Maker, it could be due to a couple of reasons. The water trough level might be too high, so adjust the ice thickness float. Alternatively, the power button might have been turned off/on during the freeze cycle, leaving ice on the evaporator, or the ice damper was opened then closed in the harvest cycle before the ice released, so allow the ice to thaw and release from the evaporator, then restart the machine.
