Frigidaire refrigerator not dispensing cube ice?

Frigidaire side/side Gallery series
Model # glrs267zcw0
Icemaker Model # GSI-26

PROBLEM:
Unit will not dispense cube ice.
Choosing "crushed" produces crushed ice.
Choosing "cube" also produces crushed ice.

The green LED indicators illuminate properly for cube and crushed.

The plunger/lever in the back panel stays in the "up" position.

There is no noise when switching from crushed to cube to indicate the lever has disengaged the blades.
