Product review (5 stars): If your Frigidaire refrigerator is in a cold garage, buy this and avoid an expensive service call!
I purchased an inexpensive 15 cu fr Frigidaire refrigerator for my garage. As the temperature dropped below 55 degrees this winter, I began to notice that everything in the freezer was beginning to melt. Upon calling the repair person, I was told that this is a common problem with these refrigerators because, due to having only one thermostat (rather than separate thermostats for the refrigerator and freezer), the refrigerator thermostat will ofter stop the compressor before the freezer reaches the expected temperature. The "answer" was to pay $100 to add this garage kit to the refrigerator. Amazon.com seems to have everything, so a search quickly found this item. It is exactly the same kit that is shown on Frigidaire's website, except it costs only approximately $26. Installation is as simple as removing four screws from the plastic thermostat housing in the top of the refrigerator, bending this foil-backed heater wire into shape, attaching it inside the thermostat housing with the self-adhesive backing and then connecting the wires.

Although this does allow the freezer to reach the proper temperature (approximately 5 degrees F), it does so by slightly warming the refrigerator thermostat in order to increase the amount of time the compressor runs. This is a work-around for a poor design by Frigidaire. Now the compressor runs much more than should be necessary (counteracting the added heat from this heater wire); which will result in a more expensive electric bill. If I would have known about this issue, I would have purchased a different refrigerator. That said, this kit is a great purchase from Amazon.com and at a great price. In order to improve the refrigerator during warmer months, I plan to attach a small toggle switch to this heater so I can easily turn it off when it is unnecessary.
