How to adjust water level in ice maker

Hello Tasker;

My name is Peter. I am a retired field service refrigeration technician.

You did not provide a model number which is located on a label on the liner side wall of your refrigerator section, so I do not know what ice maker you have.

Most ice makers do not have a water fill adjustment. If you have a square box cover on the front, then you may have adjustment. On the right hand side there may be a tiny plastic stem with a slot for knife or tiny flat head screw driver. Turn only 1/2 clockwise. Or with difficulty pop off the front cover and you will see an adjustment spring for water fill.

But, I do not think this is your problem.
1.) Your water fill tube my be iced up inside. Using a small screw driver break the ice up in the fill tube.
2.) If this does not solve your problem, then you probable have a bad ice maker solenoid, where either the coil is weak or the spool sticks and does not open all of the way for the fill cycle.
This is easily replaced. It is probably a duel valve assembly where you have to replace the whole assembly.

a.) Locate your model number.
b.) Go into the below website, put in your model number, you will get parts diagrams prices and part numbers.
c.) Go into the internet and search the part number for the valve. You may be able to find a used valve for conservable saving.
d.) Up plug the unit. Turn off the water supply valve.
e.) Remove the back bottom cover.
f.) Disconnect the valve assembly retaining screws that hold the valve assembly to the unit.
g.) Remove the electrical connectors on the valve assembly.
DO NOT GET THEM WET.
h.) Remove the main water supply line to the valve assembly. There will be water in this line.
i.) Remove the plastic tubing to each valve. Push down while holding the small retaining locking ring. When reassembling, push the plastic tubing down, not hold the retaining ring. You should hear a click meaning it is locked in.

Subzero 642. Ice maker froze up (3 inches of ice surrounded it). Repairman steamed it loose. He could not run diagnostics because Subzero Tech Support was closed for Easter holiday. Yesterday evening

This is either the defrost sensor or the main board. Neither of which you can do anything about with no parts. https://www.repairclinic.com/RepairHelp/How-To-Fix-A-Refrigerator/55-114-539299-/Sub-Zero-Refrigerator-not-defrosting-642

Sub Zero 642 side by side, refrigerator side not working.

If the refrigerator compressor runs and cools when you use the manual activation mode but does not run normally then the control board would be what I would suspect. If it has the manual activation then it is new enough to give error codes. If it is not running and not recognizing it's not running, something is wrong with the control. Unless you are seeing two dashes in the refr display. That would mean the refr section was disabled.

Does a refrigerant leak mean we must replace the evaporator of our subzero 642 side by side?

Hi,

Thank you for all this important information. Your units average life span is or can be up to 30 years, with this being say. The rule of freon is 5% less in a 12 month period is allowed, over that it this unit must be fixed, charging a leaking unit with out a plan to fix is against EPA guidelines. Now Verify the age of this unit, if 12 years or younger the parts are covered under factory warranty. You can call the factory to verify this if you like. Back to your question, yes the evaporator is most likely the reason of less freon. I personally change 4 to 5 a month during this time of year. Your evaporator part number is 4204430 and a drier 7006964 is needed also. Call subzero for assistance if you like. Good Luck, remember your unit was and investment for this is just a maintenance issue after about 10 years.

My Sub Zero 642 is freezing my fruits and vegetables

Usually a bad thermostat, but it can be a freon system problem, or a problem with your evaporator fan motor. These are problems that a good Sub Zero technician needs to repair, especially if you have a system problem, since a system problem is under a 6 to 12 year warrantee. Make sure that the company you call is a Sub-Zero warrantee company. Good Luck, Appliance Specialists
