Defrost Timer - 60Hz 120V
Part #215846602
This Defrost Timer works like a clock by switching on the defrost heater circuit after a predetermined amount of compressor run time. This allows the defrost circuit to clear the evaporator of ice or frost to maintain proper airflow. The defrost timer is located in the control housing which is in the refrigerator section of your appliance...Read more. If this part is not working, it can lead to temperature increases in your refrigerator. If the compressor circuit fails, no cooling will take place; if the defrost circuit isn't activated, ice will quickly build up on the evaporator coils and reduce airflow and efficiency. If the timer doesn't advance or if the contacts have no continuity, the timer will need to be replaced. This timer measures approximately 3 inches long and 2.5 inches wide, and is constructed of plastic and metal. It comes in black/white/silver and is sold individually. This replacement part features 1 defrost timer.

Refrigerator ran frequently and freezer door was sagging
38 of 46 people
found this instruction helpful.
I pulled off the old door gasket which came off really easy. I was hoping the new one would go on as easy as just popping it in place but it didnt work. I had to remove the inside door panel. The gasket wouldnt lay entirely flat in the inside groove so I used a bead of RTV around the entire circumference which helped to hold it in place w

hile reattaching the panel back onto the door. The screws fit on the under side of the magnetic portion of the gasket. In order to access the screw holes the gasket has to be lifted which sometimes causes the gasket to pull from the lip on the back side of the panel making the RTV get everywhere. After every screw was in place and lightly tightened the panel had to be adjusted to allow for the proper closing of the door. This was the worst part, fortunatly the screws left a slight indentation of where they were before I removed them so it gave me a nice reference.
The hinge part of the new gasket requires a lubricant so it wont bind up when the door is closed. I didnt know about this until my order arrived and a part number was recommended for the type of lube. I just used Vasolene and it works fine.
The pin bearing was really easy. Just unload the contents from the door, mine was the freezer door. I popped off the cap covering the screws and removed the screws while holding the door so it wouldnt drop on the floor. Once off I used a flat head screwdriver to pry out the old one and a light tap of a hammer to replace it with the new. I put it all together the way it came off.
Now my fridge runs much less and the freezer door doesnt sag.
