Product review (5 stars): Should be on every fridge
Every fridge should have one of these.  If electricity shuts off for a few seconds, when the fridge tries to turn back on, compressor will still be hot and a little safety switch will trip.  Over time, maybe after 15-20 trips of the switch, it goes bad and the fridge won't start.  That part is not too hard to replace, but it can be hard to find and usually costs $60 or more.  Paying a repair tech to put it in would probably be a couple hundred $.  The places that sell it usually aren't open in off hours, so your food goes bad. Having this delay / surge protector allows the fridge to cool down, then when the surge protector allows electricity to flow again, the compressor has cooled enough to start without tripping the safety switch. Hopefully this surge protector lasts longer than the safety switch.  It sure is easier to install than the compressor safety switch.
