ice maker problems

If your ice maker isn’t working, don’t run out and buy an ice maker before properly diagnosing the problem.  Slow and no ice production or other ice maker related issues can be caused by a few different components including the water inlet valve, fill tube, ice maker, or freezer temperature settings. Use this troubleshooting guide to narrow down possible ice maker failure problems.

Ice maker won’t shut off: If your ice maker won’t turn off, the problem is likely the result of a stuck or broken ice level feeler arm. The feeler arm detects when the ice bin is full, and in turn, shuts off the ice maker. When the feeler arm does not properly engage, then the ice maker will continue to produce icewhich will lead to over production. Attempt to free the feeler arm, but if that doesn’t work, you’ll need to replace the ice maker.

common ice maker failures

Ice maker doesn’t make ice: If the ice maker is not producing ice at all, then the problem can include several components:

  • Check the water supply. Most ice makers require 20-120 Lbs/SQ inch of water pressure to produce ice. If the water pressure coming from your home isn’t strong enough, the ice maker won’t work.
  • Check the water inlet valve. A clogged or broken water inlet valve will prevent water from reaching the ice maker. Verify that the inlet valve is working properly.
  • Check the fill tube. From time to time, the fill tube might become frozen, preventing water from filling the ice tray. Use a blow dryer to melt the ice in the tube. If the fill tube refreezes in a week or two, this is an indication of a bigger problem.
  • Test the freezer temperature. The freezer temperature must be 0 degrees Fahrenheit or colder for proper ice production. If your freezer isn’t cold enough, your ice maker won’t work.
  • Test the ice maker. The ice maker has several components that may be the problem including the feeler arm, ejector motor or gear, thermostat, and control board. If the ice maker itself isn’t working, then replacement of the entire component is recommended.

Ice is too small: If the ice is too small, the problem is likely with your water pressure. Ensure your home water supply delivers 20-120 Lbs/SQ inch of water pressure. If the water pressure checks out, then the issue is likely a restricted water inlet valve. Replace the entire valve. Cleaning the valve is not recommended, as this may cause future problems or leaks.

As with any appliance repair, be sure to confirm your diagnosis prior to purchasing or installing new parts. Most appliance parts retailers will not accept returns of opened and installed parts.
