Customer Question

My Scotsman Prodigy ice machine is showing a signal "b" that indicates the ice bin is full when in fact the ice bin has little or no ice. The freeze cycle runs 10 minutes and then flashes "bin full". It does not automatically go into the "harvest" cycle. Help me solve this problem.

Hi... let me see if I can help.

The bin stat is faulty... it gives the control the signal you have ice when you dont..

I would suggest you test the bin probe and replace if bad.. using a multimeter, test for continuity.. it should read closed with bin empty... open with bin full and ice touching it...

if the bin probe reads good, then the control may be faulty.

let me know what you find..

thank you for using Just Answer

Hi Shaithus1. Where is the the "bin Probe located on this model, Scotsman Prodigy ice machine # *****


Expert:  shaithus1 replied 1 year ago.

thank you for providing model number... for your particular unit, when the curtain remains open after the harvest, that is what tells the control that the bin is full... so since there clearly is no ice holding the curtain open.. that means the curtain is not closing correctly... please check the curtain hinge pins for "gunk" build-up... verify the curtain is hanging correctly.. and for proper swing... ie.. swings easily.. the unit could just need a simple cleaning...

Do you have a manual...?... the cleaning procedure is located on pages 38-39....

You can also test the curtain switch...

Curtain Switch:

1. Test using the controller’s indicator lights. Observe SW1 and SW2. Open and close the curtain in question. When the curtain is opened, the SW light will be ON. When the curtain gets to within a half inch of closing (at the switch) the SW light will go OUT.

2. Test with an ohmmeter. Disconnect electrical power. Open the control box cover. Unplug the curtain switch lead from the controller. Connect an ohmmeter to the leads of the switch. Open and close the curtain. When the curtain is closed, the switch is closed and there will be continuity. When the curtain is open, the switch is open and the circuit will be open.

3. Test the controller’s curtain switch circuit by jumping the connectors on J1 or J2 together. Reconnect electrical power. When jumped, the matching SW light will go out. When unplugged or open, the SW light will be ON.
