"Sometimes when it's warmer in the house it take the compressor in the fridge a couple of tries before it starts, though that could just be due to a weakening start/run capacitor."
Oooooo! I don't like the sound of that! Years ago I inherited a large Kenmore fridge from my aunt. After a year or so the defrost timer failed. The only place to get the part was from Sears at double the normal price for one. A few months later, the start relay failed. A few months after I replaced that, the compressor locked up. Time to get a new fridge.
That was my one experience at trying to save a dying fridge. Now the first time my fridge even hiccups, I start looking for a new one. Refrigerators used to be made to last 15 years or more. Not in these days, I think my last one lasted about six years.
