5) Freeze Timer
CAUTION
Adjust to proper specification, or the unit may not operate correctly.
Two new dip switches numbered 9 and 10 have been added to the improved “E” board to better prevent possible freeze ups. These settings come factory set to the default setting of 60 min. (OFF, OFF). Check the adjustment chart published in the Tech Specs for proper settings. If the old board does not have these two dip switches, (only 8 in- stead of 10), leave setting as OFF, OFF.

Setting in the prohibited range might cause severe damage to the icemaker resulting in failure.
