NOTE: Freezer temperatures above normal, 0º ± 2º F (-18º ± 1º C) will slow down the
rate of ice production. Increase ice production by setting freezer to colder setting.
1. The freezer temperature must be below 15º F ± 3º F. Otherwise the thermostat will
not close, even if ice has formed in the mold. Here's a quick check: Manually start
a test cycle (see above). If the temperature is above 15º F ± 3º F, the icemaker will
only complete one revolution instead of the normal two. If there is ice in the mold,
it will only complete half a revolution and then stall out against the ice.
2. Freezer too warm. Check temperature in freezer. If temperature is appropriate for
setting, go to a lower setting (levels 5 through 9).
3. Freezer too warm for setting. Service refrigerator.
4. Poor airflow around icemaker. Remove obstructions.
1. Shut-off arm or internal linkage is bent or broken. Repair arm if possible, otherwise
replace icemaker.
2. Shut-off switch not working. To test, raise shut-off arm to the OFF (up) position.
Start a test cycle. The ejector should stop after one revolution when it reaches the
park position. If ejector continues to rotate, the icemaker is faulty. Replace the
icemaker.
