Professional Repair Guide

What is this symptom?

Experiencing issues with your KitchenAid refrigerator's ice maker overfilling? Excess water or ice may lead to spills in the freezer compartment.

Important Tips for Kitchenaid Models

  • Ice production controls such as Max Ice or Fast Ice features can increase production and be mistaken for overfilling

Possible Causes

Malfunctioning shutoff arm or sensor

How to Identify: Ice production continues despite full bin; sensor blocked/dirty or shutoff arm stuck will not stop production

Part: Shutoff arm / ice level sensor

Obstruction inside ice maker mechanism

How to Identify: Jammed ice, food debris visible inside ice maker; inconsistent cycles

Part: Ice maker interior mechanism

Improper ice bin placement or damage

How to Identify: Ice bin cracked or not seated perfectly–shutoff arm doesn’t trigger; visible damage to bucket

Part: Ice bucket or bin assembly

High or incorrect water pressure

How to Identify: Excessively high household water pressure to refrigerator; overfill mainly after water supply change

Part: House water supply line
