Product review (5 stars): Excellent item. Works perfectly.
Our built in edgestar ice maker of a year old quit working last week. After reading some articles and doing some basic electrical testing I found the PTC start and overload mounted on the three prong compressor connection was faulty. The unit would hum for a few seconds then a clicking sound followed by another faint click and this would repeat every few minutes.  I purchased a new PTC and overload from the manufacturer for a twenty or thirty bucks and installed few days later.  Everything seemed ok for the first half dozen cycles of the ice making process but then I could tell the compressor wasn't kicking on like at first. Only a few cycles later and we were back to the hum with a click and no running compressor.  A local heating refrigeration and AC dealer carries the Supco line of products and suggested a hard start capacitor for the struggling compressor.  Unfortunately I could never find the start capacitor to wire the new supco spp5 hard start capacitor to so I tried to return it.  They have the no returns on electrical items policy so no luck there but they did now have a better understanding of the type of unit I was working on which is similar to some small AC units and small fridges etc.  They talked me into buying this RCO410 all in one or some people called it a 3 in 1 and I'm glad I did.  I replaced the little PTC and overload on compressor connection with this units wiring and connected to the power wires to the existing wiring. It took less than ten minutes to read directions and install.  It's been working fine for twenty four hours now. I'm not an expert but you can feel the compressor start now. Like it's getting a good supply of initial power to get the start windings going.  I've kept the back off the machine just to monitor the compressor and supco 410 and everything is cool to the touch.  I have nothing but good things to say about this item.  I wish Supco had better customer service to help us non experts chose the correct start kit we need for our application.  I read elsewhere and watched some YouTube videos that tried to show the supco hard start device they were using was sub par or simply not effective but I questioned if they had the correct device per the system they were testing. Again, I wish the supco website or customer service was a little more helpful.  I will update this post should anything happen in the next few days.  If you are curious this was a ZeL compressor 1/5hp with a PTC start device and overload mounted on the three pins.  No start capacitor was located as I don't think it has one.
