Gene, if it works OK sometimes and not at all other times and the compressor appears to be running, I would suggest that it may be the expansion valve that is messing you about. They are not a dynamic component but they do sometimes cause fridges to come and go. When next the fridge doesn't cool, use a drift on one side of the valve and give it a light whack (I think it's the valve on the left side of the picture). It may start cooling.
Having said that, I think 3.5 amps is quite light for an old-generation unit. Maybe that's just the fan? I have an old-generation fridge on my boat similar to yours (that is getting thrown out soon) and when it runs it draws 10 to 12 amps.
