The start device on my Thermador KBURT3661A02 built-in refrigerator began clicking constantly.  The temperature of the freezer would fluctuate between 0 - 32 degrees.  The temperature of the refrigerator also fluctuated during this time.  After installing this replacement (and also replacing the capacitor with the Amana WPW10662129 Refrigerator Run Capacitor), the temperature fluctuations have stopped.  Saved myself an expensive service call.
