The icemaker on this fridge fills but does not eject the ice.
As a result the tray eventually fills and overflows with each
cycle. Pressing the test button on the unit it cycles properly
and dumps the ice. Does anyone know what would cause
this, the service manual is not very clear on this, I'm
thinking the main board may be the problem but I'd
like to know how to verify this without just putting in
a new board and hoping it's the problem.
