FGUS2642LF2 Frigidaire Refrigerator Ice maker/water valve issue

the ice maker was not filling all the way so I turned the adjustment screw to increase water fill time. This caused a problem and the ice maker would not turn off, as the arm kept turning. Bought a new ice maker but it’s still not filling up anywhere near full. The water valve has 3 solenoids.

I checked voltage to the water dispenser solenoid—120v. But the voltage to the ice maker solenoid (had to wait for the fill cycle) is only 95v. So I put the connector from the water dispenser solenoid onto the ice maker solenoid and pressed water dispenser lever. Got 120v and the water seemed to flow just fine into the ice maker.

I assume the voltage drop is causing the solenoid to not function properly. But I have no clue why there are only 95v instead of 120v going to ice maker solenoid. Could there be a problem with the wire harness ?? Also the voltage from the connector that the ice maker plugs into is 120v, and the ice maker is working OK…

Here's the water inlet valve for your model:

You should be getting 120 volts on both.

If the voltage is less than 120 volts the isolation diodes are probably burned out. Use the diode check function

on your meter (or lowest ohms scale R x 1). Disconnect the 2 wire connector on the brown coil and insert the red test lead on the tan/yel wire. Disconnect the 2 wire connector on the yellow coil and touch the black test lead to the tan wire. Your meter should indicate 0 ohms. If it shows 1 or infinite/open replace the diodes.

Thanks for your reply Jake,

I hadn’t checked the VAC to the brown (main water) solenoid. Pressing the water dispenser, I got only 65v to the brown solenoid and 120v to the yellow.

I also tried what you wrote, and I get OL (open line) on the tan wire on the brown connector and yellow connector.

So this means it’s probably the diodes ??
Is there anything else to check to confirm this??

Yes, its the diode kit you need and that should fix it.

Is there anything else to check to confirm this??

Nope.
