Product review (5 stars): Very happy to have saved $150 plus a service call to ...
This came with a clear instruction sheet for troubleshooting and debugging problems with the ice maker and control circuits.  My boards had the correct matching clips and were the exact right size for my Whirlpool.  I replaced the emitter side first and now it works so I will save the receiver side in case I need it.  Very happy to have saved $150 plus a service call to get it from Whirlpool or my local appliance shop.
