Specifications
• The main fuse is 250 Volt, 3.15 amp.
High (line) voltage is applied to the control board at
all times. Removing the control board fuse or cycling
the toggle switch Off/On will not remove the power
supplied to the control board.
Check Procedure
1. If the curtain light is on with the water curtain closed,
the fuse is good.
Disconnect electrical power to the entire ice machine
before proceeding.

with an ohmmeter.
