Subject: <strong>Ice</strong> <strong>Damper</strong> <strong>Sticking</strong> <strong>On</strong> <strong>Indigo</strong> <strong>Model</strong> <strong>Ice</strong> <strong>Machines</strong><br />
The ice damper contains a magnet that opens and closes the bin switch. The damper and bin<br />
switch must be closed to make ice.<br />
There have been sporadic instances of ice dampers not returning to a fully closed position after<br />
ice harvest. The ice damper drags on the lower extrusion arm on machines that do not have<br />
enough clearance between the two parts. Depending on ice drop recoil, vibration and component<br />
temperature, the damper may fail to close.<br />
The ice machine will have a serial number between 1101027125 and 1101087043 and have<br />
some or all of these symptoms:<br />
• Low production (may be intermittent) with no safety limits in memory.<br />
• Owner notices the ice machine is off at a time when it is normally running.<br />
• The ice machine starts a new freeze cycle when bumped.<br />
If you determine the ice machine has this damper issue, refer to the illustrations on the reverse to<br />
repair. If the repair does not resolve the issue order part number 000002056 and replace the ice<br />
damper.<br />

The issue can often be resolved by rounding the right angle edge on the inside of the ice damper.<br />
Refer to photo’s and use sandpaper, nail file, emery board, etc. to break the edge. Both ends of<br />
the damper will require rounding of the edge. Gently cycling the damper open/closed will<br />
determine whether rounding the edge resolved the problem. If the damper sticks after rounding<br />
the edge, replacement of the damper will be required.<br />
