Good afternoon all, Our 11 year old Whirlpool GS6NBEXRL01 is not making ice cubs again. I had an issue when we first moved into this house 8 years ago and was able to resolve the issue by replacing the ice maker control module (AP4359694). ( http://forum.appliancepartspros...rl01-not-making-ice.html) 5 weeks ago, the ice maker stopped making ice, so I began the basic troubleshooting steps as outlined on various posts. It turned out the ice cube level sensor/optics were bad. So I replaced them and the ice make worked for nearly a month and then stopped again last week. I've tried running a harvest cycle, it didn't initiate. I've tried replacing the ice maker control module again, no luck. the harvest cycle won't initiate. I've tried pouring ice into the ice tray and letting it freeze and it didn't do anything. The ice cube arms are pointing forward and slightly above level. Any additional troubleshooting step suggestions? I am very handy, have a multimeter and am willing and able to test (or retest) as much as needed. Thank you in advance for your time and any assistance you can provide, -Ed

Hello, Ed. Please describe more detailed how did you do it?

Hi Gene, I put an insulated jumper wire between T and H for over 10 seconds, with the optics able to see each other, and the freezer door light switch pressed. The wheel/blades didn't move at all and there was no click. Is that the correct method or is there a different process to follow? ( https://www.manualslib.com/manua...lpool-R-106.html?page=23) Also of note, I didn't see any voltage on the multimeter when I tested points L and N. But I do see ~34.5 on the wires on the supply plug. That made me wonder if the wiring on the icemaker itself could be bad, or the unit, etc. The unit is thawing out right now and I will rehook it up later tonight and perform more tests with the multimeter. Thanks, -Ed

Hello, Ed.
The ice maker receives power (120VAC) from the receiver optic board (on the right hand side) through the outlet wall plug. So the cause of the problem can be 1. a bad receiver optic board, 2. poor connection at the optic board plug or 3. a broken wire between the receiver optic board and the outlet plug.
Try to do this: disconnect the power from the refrigerator. Remove the receiver optic board. Insert a short paperclip in the black/white pin (#4) and another one in the white pin (#8), this makes it easier to measure voltage. Make sure they are not touching each other or the cabinet. Make sure the optic beam is open and the light switch is off. Carefully restore the power to the refrigerator. Measure the voltage between pins #4 and #8. The normal reading is about 115 VAC.
If the reading is incorrect, the optic board is bad.
If the reading is correct, unplug the refrigerator. Make sure the connecting plug at the receiver board is connected well. Put the receiver optic board back. Reconnect the power and check the voltage at the ice maker wall plug with the optic beam open.
If the reading is incorrect, a wire inside the wall is broken.
Good luck.

I unplugged mine for 30 seconds and now it's working.

My problem with the same fridge is exactly like this. The maker stopped making ice so I replaced the optics. Started working fine again but I had only replaced the sender board so decided to replace the receiver as well....with the power on as usual...who worries about 115 volts and I needed the light.
Now the optics are back to blinking twice no matter which receiver board I use.
Did I blow the boards...are they sensitive

Dear Gene,
Many thanks for the info. New optics installed and ice working again.
I should have realized that the optic switch was static sensitive when it arrived in anti static packing.
A quick test to make sure it was not the ice maker is to jump the black/blackwhite wires on the receiver harness. If the ice maker works replace the optics....and yes it did.
Many thanks for the expensive lesson....but learned.
Tomok

You are welcome, Tomok.
I'm glad you were able to fix it!
Gene.
