MAIN FUSE

FUNCTION
The control board fuse stops ice machine operation if
electrical components fail, causing high amp draw.
SPECIFICATIONS
The main fuse is 250 Volt, 7 amp.
High (line) voltage is applied to the control board
(terminals #55 and #56) at all times. Removing the
control board fuse or moving the toggle switch to
OFF will not remove the power supplied to the
control board.
CHECK PROCEDURE
1. If the bin switch light is on with the water curtain
closed, the fuse is good.
Disconnect electrical power to the entire ice
machine before proceeding.
2. Remove the fuse. Check the resistance across
the fuse with an ohmmeter.
