Hi @jcg39575
It seems like there may be a slow leak somewhere and it freezes and then continues to build up. You may have to remove the ice maker and check where the water is coming from.
Here's a [document|38770|service manual] which is also applicable to your model.
Go to p.87 to view information about the ice maker.
Here's the [document|32672|mini manual] for your model that may also help. Run the diagnostic tests as described and check if there are any error codes pertaining to the ice maker, being shown.
