Product review (5 stars): Exact factory replacement for Whirlpool FSP #106-626662
I have a 10 y/o Whirlpool fridge with an FSP icemaker #106-626662 that stopped heating correctly causing hollow ice cubes and eventually it ended up turning the tines into the ice cube partially melted (or partially frozen depending on when it was happening) and would stop then get frozen in the cube and never turn again without forcing a harvest cycle.  (I also had low water flow from my water line so I screwed the valve at my copper water line in and out a few times leaving it opened completely at the end and that fixed the low water flow at both the water dispenser and the icemaker. Must have had some build up at the hole in the copper line.)  Buying the tray/heater element was more expensive than this almost complete icemaker.  My wires went thru the inside wall so I wasn't able to swap out the wire connectors that came with it but thankfully my old set hooked up perfectly. The front portion and shutoff bar fit perfectly on this new one.  For less than $50 we're good as new.
