Product review (5 stars): You can save the money and do it right - with just two screwdrivers
My icemaker was not working. Calling in a service "professional" would be very expensive and I knew they would just swap out parts.  So, I figured I could do that myself.

First  I replaced the icemaker itself but it only made one tray and then stalled for a couple of days.  Thus the next step was this control.  I contacted the seller to be sure it was the right one for my model refrigerator and then ordered it.  I also had watched the install video, and it was a very simple project.  Since the refrigerator was 12 years old, I figured replacing a few parts was worth it.

When I opened the package there were a ton of warning statements and "for professional installation" cautions.  I understand why they would put these in, but I've done electronic repairs for years, so I proceeded, taking full responsibility should something go wrong.

Replacing the parts was a 15 minute job.  It involved removing 6 screws, unplugging the modules from the box, replacing the boards on their brackets, plugging them back in, and replacing the six screws.  Of course, the wise thing to do was turn off the refrigerator, then unplug it first.  This not only prevents shocks, but any damage should you bridge contacts, etc.

When everything was back in place, I plugged in the box, turned it on, turned on the icemaker, and walked away.  About 15 minutes later I heard the full tray of ice drop, the water fill ... a sound repeated several more times ... and then this morning I had a full bin of ice !

The cost for the service center to replace the icemaker and these two pieces would have exceeded $ 600.  My combined cost was under $170 and took less than 30 minutes total.  There are videos on the web that show you exactly how to do the work.  If you want to save money, you can do it.

In summary:
+ Call this vendor to be sure you are ordering the right parts.  Have your make and model info handy.
+ Watch the videos to see how to do it.  Don't think you'll just figure it out ... that may make the project much harder
+ Turn off, and unplug the refrigerator and Ice maker
+ Take your time and don't force anything.
+ Take someone to dinner with your savings and celebrate your success
