This is a 120 volt defrost timer manufactured for refrigerators. The defrost timer manages the automatic defrost systemin the unit. It acts like a clock by switching between activating the cooling cycle and the defrost heater to maintain the set thermostat temperature, preventing the unit from being too warm or cold. The defrost timer may need to be replaced if the fridge will not maintain its temperature or has frost buildup. Depending on the model, it could be located on the rear panel or ceiling of the fresh food compartment. Be sure to disconnect power to the refrigerator before replacing this part.

Temp alarm sounding and food on top shelves partially thawed

After silencing the alarm, it seemed to be running as normal without any unusual noises, but food was starting to thaw from the top shelf on down and condensation was dripping from the roof. We were able to place most of the food in 2 large ice chests and then the rest in the freezer compartments of 2 fridges we have in the house. I then turned down the temp dial to the coldest setting and let it run for an hour or so; no change.

After researching on the internet, it sounded like our symptoms could be pointing to a defrost timer issue. I pulled the freezer away from the wall, located the timer and used a large screwdriver to slowly advance it. While doing this, at one point I could hear the compressor kick in. I pushed the quick freeze button and let it run for a while. When I checked it in a few hours, the alarm light had gone out and water that I had placed inside was frozen. We took a chance and put the food we placed in the ice chests back in the freezer. Everything was fine several hours later.

I ordered a new defrost timer, it arrived in a couple of days, and replaced the old one with it in a matter of minutes by disconnecting the wire harness from the old timer, removing the 2 screws holding it onto the bracket, screwing the new timer to the bracket, reconnecting the wires harness, and done. It's been a week or so and no problems.

This part is a replacement door gasket for your refrigerator/freezer. The gasket is made of rubber and is black in color. The gasket runs along the perimeter of the refrigerator door and is used to keep a seal, so the refrigerator remains cold. If you notice that your refrigerator will not maintain a steady temperature or if it is noisy, it could mean that the gasket is torn or damaged. This product is sold individually and is an OEM part from the manufacturer.

This part is located at the bottom of the evaporator. The defrost heater heats the evaporator in the defrost mode of operation to keep the cooling coils from frosting over. The thermostat must be replaced when replacing the defrost heater.

This gasket retainer clip kit is for freezers. There are 24 pieces in this kit. The clips are what secure the gasket and liner to the freezer lid. The clips are white in color and made of plastic. If you notice frost build up in your freezer or that is it is not maintaining its temperature, this might be because the retainer clips have broken, and this has caused the gasket to become loose. This is a genuine OEM part that is obtained right from the manufacturer, ensuring a quality repair.
