On top of good reliability, they cost around $5 each, compared to like $30- 45 for the exact replacement item. You can replace the klixon also for around $12
WR8X122 or AP2061490, however, I usually dig out the old one as they are very reliable. As you are aware, I triple check how I wire them up as some compressors have the same resistance for run and start windings. Suspect if you wire it up wrong, the klixon will save the compressor if you run power direct to the start winding!! Will try that to a worn out compressor next time I see one.
