The refrigerator / freezer works great, but a reoccurring problem for years is the defrost drain hole from the freezer to the refrigerator freezes up a few times a year (or more). This causes a water backup which eventually it "rains" in the refrigerator. I found part AP118347 on your site "Drain Tube Freeze Up Kit" which I assume was an add on from the mfgr to deal with this issue. How does it install, does it come with detail instructions for installation into a unit that doesn't already have the wiring in place, etc. I think the settings in the freezer & frig are correct as I don't have ice in the milk and the ice cream is hard. The seals around the doors all look good. I don't have moisture around the door openings, etc. Can you help?

Thanks Gene for the response. I've dealt with the problems for years and appreciate your professional input to help me resolve it.

pjy,

What is the complete model number of the refrigerator?

Gene.

Locate the drip tray (#26 on the break down diagram) under the evaporator coil. The drain hole is in the center of the tray.

Use a hair dryer to defrost it. You can install the drain tube freeze up kit (#20 on the break down diagram) to prevent future freezing.

Here are the break down diagrams for the Amana refrigerator Model TL20N

Gene,
I have an Amana BX21V bottom freezer and it sounds like I have the same issue. When I removed the rear panel in the freezer, the coils were completely frozen. I defrosted it several times and it keeps occuring. Would the Drain Tube Freeze Up Kit (AP118347) also work for me.

Thanks
