Last week I noticed that my heat pump wasn't working right. I called Raypak - the rep walked me through a few things and determined that the problem was either the capacitor or the contactor.

I received both parts but no instructions. It looks like both should be plug 'n play, but thought I'd check here for any advice on what to make sure I do (triple check that the breaker is off) and what to make sure I don't do.
Here are the parts:
