I’ve replaced a couple dozen. When I started out, all I had to do was buy a cheap (but reliable) multimeter and spend a half hour or so watching YouTube vids on how to test those kinds of capacitors.
They can be deadly dangerous if you don’t take precautions. It takes very little skill to replace, but the power to the compressor needs to be cut and the Fan and Herm terminals do need to be grounded/discharged to the common post before handling.
It’s still a very basic repair, though, and even in the +100° temps we’ve had here, it was worth the effort and only takes about ten minutes to remove, five to test, and five to replace and close it all up.
That feels like it would be very open to abuse: OP can edit the post later to read:
“Upvote and comment to show your respect for the Proud Boys who are staying strong! The government has become our Yoko Ono!”
Then readers will all wonder if this is new code talk and be surprised by the votes and engagement.
