Unit is off& Refrigeration diagnostic light is on or blinking. Possible Cause,( Low discharge or long freeze cycle. Probable correction, if the Refrigeration light is glowing steadily there is a probable refrigeration problem.) 2. Possible cause. Harvest problem. Probable Correction. If refrigeration light blinks once and repeats, Look for a harvest Problem.**On Controllers 17-1 and higher, This also indicates that cubes were (sensed) by the bin controls. 3. Possible Cause. Hot gas valve failure, Probable Correction. Check hot gas valve operation. 4. Possible Cause, High Discharge Temp. Probable Correction, If the refrigeration diagnostic light blinks 3 times and then repeats, check for a reason for high discharge temperatures. 5. possible Cause, Harvest problem. Probable Correction, Controllers 17-1 and higher, if the light blinks 2 times and repeats, check for a harvest error- no cubes sensed. 6. Possible Cause, Unit dose not go into harvest - exceeds maximum freeze time. Probable Correction, Push and release off button. Push and release Freeze button. Check operation. next Push cube size float down and check operation. 7. Possible Cause, Exceeds maxi harvest time. Probable Correction, Check for cause of long harvest cycle. Try not to put any gauges on system until you have to. Every time you do you loose refrigerant out of the system.

Well it is making ice cubes alright just too thick right? I would give it a good cleaning with nickleguard and retry. If it is still doing the same thing I would replace the ice thickness switch.

The older cubers were opperated by a cube size thermostat. when the temp reached the cube size tstat setting it would energize a harvest timer motor and this timer would continue running through a holding switch on the timer. when the cam comes around and the micro switch drops the water is introduced (it would be warm) and the hot gas from the refrigerant would be introduced to the evaporator causing the cubes to drop. at the end of the cycle the cam pushes op in the holding switch and finally open it and because the cube size tstat is now warm the timer motor stops.
The timer had a white plastic stem with a 1/4" D shaft. It would only turn clockwise. Try looking for this and advancing it to see if your sol valve will open or get voltage to the valve.

is the drain running clear is the condenser clean and are both spray nozzles in place?
SOURCE: Scotsman ice machine is not making ice. There is
The manual has an exploded parts diagram use as guide to locate parts.
First check the timer, you can manually turn it through a cycle or watch it rotate on its own.
Check the water inlet solenoid valve. if all looks well and you have definite water flow past the valve, then
Check spray pump. You have to remove the rear panel. The pump has a fan on the top. spin the fan if it is at all tight the ;pump is bad.
I have owned 2 of these units and have had failures of all of the above parts over the years.

Clean the bin eyes found in the back of the ice machine where the shoot narrows. Look on the left and right sides of the unit, you will see plastic vanes that are pushed into rubber grommets. Just pull the eyes out and clean with ice machine cleaner.
