Kitchenaid Superba ice machine cleaning light blinking

Kitchenaid Superba under counter ice machine stops making ice during first cycle then cleaning light comes on and blinks steady.
Light comes on after slab has slid off cold plate on to cube cutter grid.
Ran cleaning cycle with nickel safe cleaner but problem not solved.
Both thermister plugs look clean but I have not checked resistance yet.
Condenser clean, gravity drain clean.
I’m thinking that maybe evaporator thermister might be the problem?

This was my ice machine post, replaced evaporator thermistor, problem solved.
