funny, your post showed up in italic script on my iphone but on mozilla here it's comic sans.
anyway, i guess that was the point of my question - where the heck are the compressor specs. i can't find any info on the internet but maybe i am not looking hard enough. sounds like you are saying the specs are in the service manual. maybe i should get one of those.
i guess my condenser fan is probably within spec if my RPM measurement was good.
when you say 36-38F inside, do you mean the air temperature? in my latest test i put about an inch of water in a glass and dropped the tip of my fluke's temperature probe in the water. it reads between 38F and 40F.
anyway i have actually been turning the thermostat down since i found the air temperature to be < 34F at some point. per the leaflet that come with the thermostat, i set it to 7 on installation and right now it's on 5. what is the range of temperatures one can expect to find, say if the thermostat is set to 1 vs 10? is it only a few degrees F for the whole range? i suppose this depends on whether or not the sealed system is working properly.
the history here is that a couple years ago the freezer thermostat failed in a closed position. this caused the freezer to run nonstop. when i replaced that thermostat, i noticed that it was pretty badly corroded. the refrigerator thermostat was also corroded (and the knob was stuck on 7) but everything seemed to be working so i left it be. then a few days ago i noticed that the compressor was off for a long time and it was quite warm in the fridge. i shorted across the refrigerator thermostat input on the compressor relay and it started right up, so i decided to replace the thermostat. in truth the thermostat seemed to be intermittent - after noticing the problem but before i replaced the thermostat, i noticed that it was cycling properly.
since replacing the thermostat, it's been maintaining the set temperature just fine. but i started wondering if it was working too hard, hence the thread.
if the only way to properly diagnose this is to look at the frost pattern, then i guess i have to incur the wrath of the family again and empty the fridge.
