      Having laid some theoretical groundwork in the last webinar, we're going to focus on practical considerations in this one. That means quick n’ dirty techniques for diagnosing sealed system problem using strategically chosen and skillfully interpreted temperature measurements.  Review homework from the first session on 10-2-2017. Home refrigerator practical design and operating rules-of-thumb useful for troubleshooting Practical application exercises Troubleshooting scenario exercise Techniques for making system temperature measurements for determining superheat and subcooling Sealed system diagnosis homework assignment (to be reviewed in the next webinar in this series) If you attended the first webinar in this series, this is your payday! We’re going to apply that keen, penetrating insight you now possess into money- and time-saving shortcuts you can use to diagnose real-world refrigeration systems on service calls.

How to manually cycle the GE WR30X10093 icemaker

Samurai Appliance Repair Man

19,677 views

A useful and handy diagnostic technique when working on an ice maker problem is to manually initiate a harvest cycle to see with the ice maker will or will not do. Here's how to manually cycle the GE WR30X10093 ice maker:

Power On Diagnostics

When the icemaker is first connected to power and if thermistor temperature is 50°F (10°C) or higher,

the control will perform a Power On test before entering the freeze cycle.

The test consists of the following:

• Turn on the motor until it reaches home the next time.

• Turn on the water valve for 1/2 second.

• Tum on the heater for 1/2 second.

• Verify that the feeler arm was in the "in" and then in the "out" position.

• Verify that the motor was not in the home position and then in the home position.

• Verify that the motor does not remain on after being turned off.

• Proceed to the freeze cycle.

Note:The power on test will only add 1/2 second of water, which will not overflow the mold with a normal fill,

but may cause a small cube when the refrigerator is first started.

If the temperature is below 50°F (10°C), the control will power up normally.

If in the home position, the control will enter the freeze cycle.

If the motor is not home, the control will enter the harvest cycle but bypass water fill to avoid overfilling the mold.

Service Diagnostics

During the first 15 seconds that power is first applied to the icemaker,

the Service Diagnostic Test mode may be entered.

The service mode is entered by pushing the feeler arm from the "out" position to the "in" position

and back again 3 times and only 3 times within 15 seconds.

Note: If the icemaker has already started a harvest cycle and the arm is moving,

it may be impossible to properly move the arm and enter the service mode without allowing it to reset and powering up again.

The service diagnostic mode consists of a harvest cycle followed by a water fill.

The harvest cycle is entered immediately, regardless of icemaker temperature or arm position.

While in the harvest cycle in the service mode, the heater will remain on for a minimum of 20 seconds.

The water fill cycle will initiate the first fill (5.1 seconds) without waiting for the mold to "prechill".

Only one water fill occurs during the service mode, whether the thermistor has reached 39.2°F (4°C) or not.

The icemaker will exit the service diagnostic test on its own and enter the normal freeze cycle.

If the ice maker won't do the manual harvest, replace it. Here's the replacement you need: http://www.repairclinic.com/PartDetail/Ice-Maker-Assembly/WR30X10093/1399596
