Question about U-Line Icemaker
Apparently there is a solenoid valve that reverses the flow of refrigerant when the controler board tells it it is time to harvest ice. my unit has always had problems but recently has developed an intolerable issue whereby the unit begins harvest mode after 10 or more cycles and gets stuck in harvest mode. this causes the grid to get hot and stay hot, 100 degrees or more. the compressor continues to cycle, fan runs, etc. but the grid remains hot. i am told that this is due to faulty solenoid valve and am going to order this part and attempt to get it repaired. any ideas beyond this would be great.
Have you got the equipment to change this solenoid valve? you will need a vacuum pump to evacuate the system once you have changed the valve, and the equipment to charge the system with refrigerant (gas).

Hi and welcome to FixYa, I am Kelly
Here is what the manual says:
3. Icer-ette freezes but water does not come into mold; no ice production.
3A. Nonfunctioning water valve assembly. 3A. Clean or replace solenoid valve assembly.
3B. Mold heater assembly. 3B. Contact Raritan Technical Support.
3C. Water supply turned off. 3C. Provide pressurized water.
3D. Icemaker module. 3D. Replace icemaker module.
3E. Cold control. 3E. Replace cold control.
3F. Bad wiring harness plug contacts. 3F. Contact Raritan Technical Support.*
Although this is for troubleshooting non optical sensor refrigerators:
The troubleshooting procedures for cycling the unit are exactly the same,
The ice maker module part number for the 120V unit is PN 628366 (do a net search for this part number and save yourslef a bumch of money if you fetermine your moduleis bad) You start the harvest cycle by removing the front cover and then jumpering test points T to H. The white dial will begin to move if there is power to the module. Remove the jumper when the sweep arm reaches 5" o'clock and let the ice maker automatically cycle. It should harvest, and fill in on complete turn of the white dial. If it does not fill you probably have a water supply or water valve problem. There is an inline input power fuse for the ice maker. Power should come in via the red wire.
Mind you the ice maker has an internal thermostat behind the module assy that has to reach 15 deg F to start the harvest cycle. When you jumper T to H you are bypassing the thermostat. If the thermostat fails or the unit does not reach 15 deg F then the harvest cycle will never begin.
