Defrost Thermostat

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. Replaced the timer with new one. Second I removed all food from freezer. Took of back of freezer wall with nut driver. Located the thermostat which was very easy to remove. Just one clip holding thermostat. Unplugged the two wires from the old thermostat and plugged in new wires. Thanks to Partselect.com, the parts were an exact match. Very easy to do. Saved my tons of money. Freezer and refer works like new.

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 defrost 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.

THERMOSTAT--First I removed the fours crews that hold the back of freezer (inside freezer) in place. I then pulled the thermostat out about 3 inches and disconnected the two wires. Plugged in the new one and put back in place. Replaced freezer back and installed the four screws that holds it in.(iIf your freezer has a ice maker just loosen the 2 screws that hold it and lift the ice maker up off the screws
DEFROST TIMER--- removed one screw inside fridge by light bulb that holds in the timer and setting knob, then took out the two screws that held in the timer unplugged the old timer and replaced with the new one put back in the two screws that holds the timer in then replaced the one screw that holds the unit in place

At top of refrigerator compartment, took out screws to cover (where temp control is) and to the right took out 2 screws to remove defrost timer and installed in reverse order. In freezer compartment, unscrewed back of freezer wall and took off completely. Removed old freezer thermostat, the body of freezer thermostat snapped onto coil and wire plugged in. Let run for 24 hrs, then made adjustments to temps, so far temps are back in normal range.

remove all freezer items and remove back panel covering the coils - about 8-10 nuts using a nut driver. The coils in my refridgerator were covered with a heavy frost - thermostat was also frozen over. Manually turn the defrost timer so the fan turns off to observe if the heating element is working (defrost timer is on the bottom front of the refrigerator on the left side). My heating element did work so I decided to replace the thermostat and defrost timer. Unplug the refrigerator. Disconnect 2 wires connecting the thermostat and unhook. Replacing with new thermostat - red and white wires that have male/female connectors and hook onto coil as before. Note that two parts with similar names were offered by PartsSelect and you really couldn't tell which was the right one - I got both but returning the unused one was very easy but cost a couple of bucks in shipping. Next, take out two screws and the bracket that holds the defrost timer in place and unplug it. Plug in the new one and screw it back in. Reinstall the back panel - throw out all that stuff in the freezer that you've had in there for 10 years and turn it back on - very simple and it worked perfectly. Very good experience with returning parts - excellent customer service.

took the shelves out, unscrewed the rear panel,unpluged the thermistat and uncliped it from the line.Replaced with new thermistat in the reverse order. Before turning the unit back on,allowed the coils to defrost.All of the process was shown in your vidio that I was able to view while ordering the part. Thank you

Removed evaporator cover, unplug 2 wires to thermostat, unclipped it from the coil. Installed new themostat back the same way.

Replaced both the thermostat and defrost timer and still froze up and still warm air to the fridge, turned out to be the defrost heater coil. It was cracked in the middle, very easy to test with a multimeter. Replaced the heater coil and all is like new!

I turned the refrigerator off and took the screws from the inside back panel of the freezer. Then I took two mounting screws from the evaporator letting it pull out at the bottom a few inches. Then I removed the Defrost Heater and installed the new one. Then I put the mounting screws back in and replaced the Thermostat. Then I put the back panel back on and turned the refrigerator back on. It has been working for now.
