This Refrigerator Freezer Modular Ice Maker Kit is an accessory kit for your refrigerator's ice maker. It is intended to fit compatible Whirlpool brand refrigerators without the ice maker in the door; check to see if your model number is compatible. This kit includes everything you need to install the ice maker for the first time or replace an existing ice maker. For refrigerators with an automatic ice maker, or self-filling trays, you'll need to purchase a copper tubing kit that contains a ?Regular Valve and Clamp Assembly. We strongly recommend that you hire a qualified technician to safely install the water line and ice maker. Replacing this accessory will require advanced mechanical training. You must unplug the refrigerator or shut off the house circuit breaker for the appliance before installing this part. Also turn off the refrigerator's water supply before you begin.
