Raritan icer-ette only filling 5 of 8 slots in ice mold

How old is the unit? The water delivery pump and hoses will wear out and leak over the years of service. This will happen to ANY icemaker product (refrigerators, etc)

Possible restriction in the water fill line to the ice maker. Possible ice build up in line.

Ok 32 deg is freezing. If compressor is running and condenser fan is running and refrigerant psi is good then lets check Malfunctioning water valve assembly, check to see if you are getting water to water valve if so then check to see if you are getting power to water valve. Check mold heater, you don't want mold heater on at this time. It sounds like you are having a water or water valve issue.

Cheaper to replace machine than to replace plate.

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.

sounds like your selenoid valve, call the company at 856-825-4900 they should give you the answer.

My unit turns on works for a while then shuts down, fan would not re-start every cycle, causing over heating and shut down, cleaned the fan, oiled the bearings, cleaned all the elec. connections, seems to work now.

it needs freeon

Each mold tray has a heating element that is turned on to free the ice cubes from the mold tray and allow them to fall into the ice bucket when the tray is rotated into harvest position. Sounds like that is not being turned on... or is defective..

the first problem is solved by reducing the amount of water that pours into the ice tray. the ice maker should have an adjustment for this. pry off the cover and look for a screw adjustment. they usually adjust volume by cw is more and ccw is less water. the last problem "melting ice" is related to the first. one way that I know how these work is a complete cycle time adjustment. the final step of dispensing is to turn on a low wattage heater to help pop the cubes out. now if the timer is running too slow, not only does too much water come in, but the heater is turned on for too long and causing "melting ice". Imagine a clock running with various events triggered by the clock's rotating switch that turns on certain components at the proper time and leaves them on for a finite time. your clock may be too slow.
