Making ice may seem simple, but the built-in ice makers in refrigerators can fail for a wide variety of reasons, from simple settings to faulty parts. Troubleshooting a Kenmore refrigerator ice maker means starting with simple fixes and working your way up to trickier and more costly repairs as needed.
Kenmore refrigerators won't make ice if the freezer temperature is set above 10 degrees Fahrenheit, with the optimal setting between 0 and 5 degrees F. Check your refrigerator to make sure the temperature setting is right, and adjust as needed until you're in the right range.
Change the Filter
Ice maker filters capture impurities in the water supply so they don't end up in your ice. If you neglect your filter for too long, it could become clogged, which would prevent water from reaching the ice-making mechanism and prevent your unit from working. Try changing your filter for a new one to see if this solves the problem.
Check Water Pressure
Ice makers can't make ice if the water pressure in your home is below 20 pounds per square inch. Pick up a simple water pressure gauge and hook it to any hose or washing machine bib to check your pressure.
Door Switch Failure
The door switch in a refrigerator alerts the ice maker when the door is open, rendering the ice and water dispenser disabled. If the door switch fails, it may fool the ice maker into not working even when the door is closed. Check your door switch for continuity using a multimeter. If you don't have one, you may be able to borrow one for free from your local library. If the multimeter indicates a lack of continuity in the switch, you'll need to replace the switch to get your ice maker working again.
Ice Mold Thermostat
The ice mold thermostat helps control the process of molding ice in the ice tray. If it malfunctions, the ice maker won't work. You can use your multimeter to check for continuity in the thermostat just like you did in the door switch, and replace the thermostat if it turns out to be faulty.
The ice maker assembly is a unit that fits inside your freezer and contains all the parts required to make ice. If you've completed all the troubleshooting steps in the article and your ice maker still doesn't work, consider replacing the entire ice maker assembly. This is the most difficult and costly solution to fixing a broken ice maker and should be saved as a last resort. While it is possible to replace individual modules in the assembly, it's generally best to replace the entire unit for the best long-term results.
