Defrosting an ice maker should be done at the very least once a year. You may need to defrost more often than this if you use the ice maker frequently or live in a humid environment. Additionally, if your ice maker is frozen solid and not or ice, then defrosting may be helpful.
Reset Ice Maker
Start with as a means to initiate a defrost cycle. The defrost cycle turns on the defrost heater, and will begin to melt stuck ice, perhaps solving the problem or making further troubleshooting easier.
- You may have to wait up to 24 hours after resetting before your appliance starts making ice again. Then, ice makers will produce 2 trays of ice every 3 hours.
When a reset does not work, move onto running a (FD) of the freezer. This looks different for each machine, so refer to the link.
- Once in forced defrost mode the heaters in the freezer will run a heating cycle for 20-30 minutes, and upwards to one hour.
- Some refrigerator models will beep every second for the entire defrost cycle. It's best to leave the room and maintain sanity.
- If you see water melting, try to remove chunks of ice from the ice maker before running another defrost cycle. This process may take 20-30 minutes each cycle.
After several Forced Defrost cycles with no melting ice, run a refrigerator defrost (RD) cycle. Your fridge automatically defrosts several times a day, but there are cases when manual defrosting is necessary, like when the ice maker is frozen over.
- Enter diagnostic mode again as you did with the , but this time select RD.
- This cycle normally takes 20-30 minutes, and may take longer depending on ice buildup.
Preventing Future Ice Buildup
After a potentially time-intensive defrost, it’s worth taking preventative measures to prevent future freezing.
- When convenient, check for frost buildup on the ice maker and wipe or scrape away the ice.
- If the frost is excessive, run the defrost cycle again on your ice maker.
- Disable or turn off the ice maker if it isn’t being used.
- Inspect and clean the ice bucket’s rubber seals to keep cold air in.
