Ice maker production slowed to nothing.

Everything tested fine so I just started parts swapping.

Ice maker
Water valve
Short pig tail from main harness to ice maker

Ice maker harness has the following wires.

White - N
Black - L
Tan - ice maker water valve power
Green - ground.

N to L 105 volts
L to green 105 volts

All these tests are before the short pigtail with the inline fuse.

However nothing happens when it’s all hooked up and I jump the T H on the ice maker.

Testing the voltage on the ice maker is still 105 volts.

So then I was thinking a current issue. So I hooked up a plain old lamp up to the black and white wire along with a volt meter. 105 volts when the light it off. When I switch on the light the voltage drops to 30 volts with the load of the bulb. Bulb doesn’t turn on.

All I can come up with is somewhere I’m getting voltage feedback or whatever on the board that sources power for the ice maker has partially failed.

Any ideas?

New main board?

If it was an issue with optical level sensor, why would I there be power to the ice maker harness?

Could it be a bad relay on the board?
