How to Repair an Ice Machine


Save money by repairing your own ice machine. Most icemakers attached to standard refrigerators operate on a simple principle: water flows into the freezer through a valve in the back. It's then funneled into a mold that forms the cubes and then freezes them. That cycle runs until the ice cube bin fills to capacity. Much of your machine's ice-making ability depends on factors within your control, such as your water supply and the temperature of the refrigerator.

Things You'll Need

  • Small screwdriver
  • Leveler
  • Check whether the machine makes too much ice or does not shut off. Look at the shutoff arm over the ice cube tray. Make sure the arm is set at the manufacturer's recommended position. Or remove any object preventing the arm from lowering into the shutoff position.

  • Determine why the machine does not make ice. Confirm that the supply line brings water to the machine. Or measure the amount of water flowing into the reservoir bin to make sure it reaches one gallon after one or two minutes. Then check if the water valve sits at the proper position to pressure water into the machine's ice mold.

  • Consider that your freezer's temperature prevents the machine from making ice. Set the temperature at 5 degrees (F) and your refrigerator at 35 degrees (F). Use temperature setting controls within the freezer and refrigerator to make these adjustments.

  • Look at the machine's ejector gear if ice does not fill the bin properly. Use a small screwdriver if your machine has a removable face plate covering the control module. Examine the unit to see if the ejector blade moves but does not push ice into the bin. Order a replacement control module.

  • Fix the machine if ice starts to taste bad or has a strange color. Wash the cube holding bin and molding tray, run water through the supply line or install a new water filter in the refrigerator. Also add a supply line filter to the refrigerator if you've never had one.

  • Repair leaks from the machine. Level both the refrigerator and the ice machine. Unplug both appliances and place the leveler on top of each. Fix the level using controls that lower or raise your refrigerator.

Tips & Warnings

  • Before trying to determine the problem, read the owner's manual which explains how the machine operates.
  • Ice machines work best when you change the machine's water filter twice a year.
  • Installing a water filter makes the ice cubes taste better.
  • Warnings
  • Before attempting to fix any problem on the ice machine, read the safety information in the owner's manual that came with the refrigerator.
