CAUTION
1. The control board is fragile; handle very carefully.
2. The control board contains integrated circuits, which are susceptible to
failure due to static discharge. It is especially important to touch the metal
part of the icemaker before handling or replacing the control board.
3. Do not touch the electronic devices on the control board or the back of the
control board to prevent damage to the control board.
4. Do not change wiring and connections. Never misconnect terminals.
5. Do not short out power supply to test for voltage.
6. Always replace the whole control board if it goes bad.
The control board provides the following safeguards:
• High and low voltage protection.
• Provides component protection during low water supply.
• Purges remaining ice in the evaporator.
• Provides short cycle protection for the compressor.
