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.

My freezer would freeze up and not allow cold air to refrigerator side. First I took off bottom face plate, located the timer on left side bottom, removed the two screws and unpluged the timer.

Freezer coil frosting up solid. Refrigerator warming

found this instruction helpful.
First - I asked a person familiar in ref/freezer repair for assistance. This was the hardest issue - trying to find someone to offer "free" advise. He stated that when this problem occurs it is usually one of two things: 1) The defrost timer (underneath Refrigerator - Attached w/2 screws and plug-n connector) not functioning or 2) The de

frost sensor (clipped-on to the coolant line (2-press-on wires) above the main coolant coil in in rear of freezer section behind panel secured w/5 1/4" hex-head screws) not properly sensing need for defrosting. The Tech. also stated that the defrost/heat coil, which surrounds the large coolant coil in the back of the freezer hardly ever goes bad unless it is the glass/clear type coil which often crack. (Mine was the black filament type element like found in an electric oven). I check the element with an ohm meter - 27 ohms of resistance which indicated it was okay). I replaced both defrost timer & defrost sensor at the same time and that fixed the problem. Parts ordered were an exact match to originals (dispite model number changes/upgrades) and everything went very well. NOTE: It is good to have the part numbers off of each original item and know what they are called before placing your order. All fixed for less than $50.00. A service call alone would be more than this. Took about 2 hours to do, due to having to defost the iced-up freezer coil w/a hair blower. Don't use sharp objects to chip away ice, let the blower do the work - Patience and a couple of towels to absorb water is important here. Hope this helps the other do-it-yourselfers.
