I replaced the capacitor and the compressor start device and that seemed to do it! No more clicking and it's not running all the time. I watched the videos for the parts. The new parts looked slightly different than the parts in the fridge, but everything connected right and this site said they were compatible so I went with it. I should have looked more carefully where the metal clip was hooked on before I removed it because my model was a bit different than the videos and it took a little bit to find just the right spot. Overall, it took longer to take breakable/heavy stuff out of the fridge and clean under/behind the fridge and around these parts than it did to actually do the replacement. Hoping this keeps the fridge lasting longer! I'll always take repair over replace.
