Have you cleaned the unit lately. There is an ice thickness probe that can be adjusted to compensate.

SOURCE: i have a model: cm250ae-1e and it is freezing over

If it continually makes a "glacier of ice" on the evap coils, and you're missing harvest cycles, then the timer is suspect. I have replaced mine approx once a year or so.

Anthony,
This sounds like a warranty situation. This would not be a install issue. You will need to contact your local service agent to check harvest assist motor.

Ice getting to thick and not dumping


go to the freeze timer which has off and on dip switches. take some freeze time out by moving the first switch to off this will shorten freeze time. Also check the harvest assist solenoid and plunger when it go's into harvest. make sure the machine is cleaned and check the cube plate to make sure that none of the plates are not loose this will cause ice to freeze between the loose spots and will not let ice come off the plate.

Sce170a-1a wont harvest


This machine has a cube size control. Which tells the machine when to go into a harvest. there is a harvest switch did you try to force it into a harvest and if you did, did it harvest. depending on ambient temperature from start of freeze cycle to harvest it should be making ice every 15 to 18 minuets and then go into a harvest. so start the ice machine and time it , run it for 18 minuets and force into a harvest. after ice drops check the ice bridge thickness. Bridge thickness should be about 3/16'' the ice dimple must not be DEEPER than 1/16". If this is good then we need to look at what is not working to harvest ice. The cube size control is a reverse - acting thermostat that controls the start of the timed freeze cycle. It must be set properly to prove the correct size cube bridge. When it is closed, an indicator light on the control board will be on. If you force it into a harvest and it harvest the ice with no problems and the ice is at the right thickness then replace the cube size control, but if dose not harvest the ice and you see the ice is at a good thickness and not to thick because if it is to thick it will freeze to every thing and will not drop. SYMPTOM. Unit freezes, but will not try to harvest. POSSIBLE CAUSE: Cube size control will not close; to check: Unplug water pump, switch unit OFF and then ON, in about 2 minutes the timed freeze light on the control board should be ON. PROBABLE FIX: If timed freeze light does not go ON, replace cube size control. SYMPTOM #2: Timed freeze light glows, but after 4 minutes unit dose not power hot gas nor purge valves Then replace control board.

First i would clean the machine per manufacturers instructions with nickel safe cleaner and sanitizer. When the plates get dirty it will cause ice to hang on to plate. Also check the thickness of ice if to thick it will not come off plate.

English instructions for saivod fhs186 ice maker


DO THE BASICS:
Change the water filter
Add ice machine cleaner and go by the directions.
What should be kept clean?
There are 5 things to keep clean:
1. The outside cabinet & door.
2. The ice storage bin.
3. The condenser.
4. The ice making system.
5. The ice scoop.
The ice storage bin should be sanitized
occasionally. It is usually convenient to sanitize the
bin after the ice making system has been cleaned,
and the storage bin is empty.
A sanitizing solution can be made of 1 ounce of
household bleach and two gallons of hot (950F. -
1150F.) water. Use a clean cloth and wipe the
interior of the ice storage bin with the sanitizing
solution, pour some of the solution down the drain.
Allow to air dry.

How to clean the condenser.
The condenser is like the radiator on a car, it has
fins and tubes that can become clogged. To clean:
1. Remove the kickplate.
2. Locate the condenser surface.
3. Vacuum the surface, removing all dust and lint.
Caution: Do not dent the fins.
4. Replace the kickplate.
Winterizing
1. Clean the machine as explained on the next
page.
2. Turn off the water supply.
3. Drain the water reservoir. See page 24, Spray
Pump Repair and follow the instructions to remove
the pump hose (step 2, bottom hose only).
4. Disconnect the incoming water line at the inlet
water valve.
5Remove control box cover and turn the timer
into the harvest cycle.
6. With the machine operating, blow air through
the inlet water valve; a tire pump could do the job.
7. Drain pump models should have about 1¤2 gallon
of RV antifreeze (propylene glycol) poured into the
ice storage bin drain.
Note: Automotive antifreeze must NOT be used.
8. Replace control box cover. Switch off and
unplug the machine.

CUBE ADJUSTMENTS
There are three items that may be adjusted: Cube
Size, Harvest Time, and Bin Level. Note: Cube
Size and Harvest Time adjustments should only be
done by a qualified service person.
Cube size control.
The cube size control should only be adjusted to
bring the cubes to the correct shape, the overall
size cannot be adjusted. Try to adjust the cube
size control when the ice machine is in the harvest
cycle, or in the first 10 minutes of the freeze cycle.
1. Open the door and remove the control box
cover.
2. Locate the cube size adjustment screw, and to
make fuller cubes, turn the screw clockwise about
1/4 turn. This will make the freezing cycle longer.
3. To shorten the freezing cycle and make cubes
that are not as full, turn the adjustment screw 1/4
turn counterclockwise.
4. After the next freezing cycle, the cubes should
have responded to the adjustment, if another
adjustment is required, do it early in the freeze
cycle.

Scotsman CM250AE Ice Machine tech help


Check the bridge size adjustment at the top of the metal grid that the ice forms on. This determines the size of the cubes. Whenever you make a repair on the water system, especially on an older unit. make sure the unit is clean. A little bit of calcium deposits (or that other nasty looking stuff) getting into the passage ways will make it run erratically, and can drive you nuts.
