[b] CHECKING CONTROLLER BOARD

* While checking the controller board for proper operation, keep all the connectors in
place, including those in the control box.
* If the ice making switch needs to be pressed to manually end a freeze cycle, wait for
at least 3 minutes after the freeze cycle begins (agitating motor starts). Otherwise, the
compressor will stop for 5 minutes (considered as low water condition).
* When the unit is unplugged, wait for 5 minutes before restarting the unit.
