solenoids fail pretty often, try powering one right from the power line
or check for power at the solenoids........

note they didnt fail together but flaked out pretty close to one
another.

I got $$#% at my ice maker wasnt certain if it was the maker itself or
the solenoid, found the icemaker jit wasnt much more than the solenoid
so bought the kit, changed solenoid problem went away.

put leftover maker in storage for later use
