    That black oil tells me excessive heat probably due to high suction SH and no water jacket!

    6 years old is that the original compressor?

    I see some metal flakes in there , normally (15+ Years) that would be expected but again in a 6 year old pump NO!

    A through investigation MUST be made too find the cause(s) of the failure and correct them!

    I would think if overheating was a problem, there would be more indicators than that, I don't see any discoloration to where the oil might have been baked on.

    Is the oil is sticky or tacky, I would believe it.

    checking your discharge temps 6" away from the comp on the other comps and seeing if it exceeds 225*F would be a good idea, if it is' then it's cooking the oil.

    I agree.

    Is there even a "cond fan motor" (body cooling fan) on these comps???

    never seen one for the 2 cylinder models!

    I do remember some ice makers installing a small 9W fan by the compressor on water cooled models, don't see how you could adapt in this situation without liability issues!

    Check the discharge temps, check the suction temps, SH and that'll tell you if it's too hot.

    I know I have a similar one for a freezer but it has a fan on it and is water cooled.

    Oil wasnít sticky or tacky from what I felt just black as heck still felt viscous. I always check sh subcooling discharge temp. I hear discharge temp + ~75degrees is the temp in the compressor from my reading and understanding and we want to stay under 300f or we will have oil burnoff.

    Nothing except for most casino is open air return but canít really feel a draft stays around 65-70 ambient.

    Air impingement on the comp body is mandatory for air cooled comps ,I thought. Thats a compressor killer w/o some sort of comp "body cooling",I thought,also.

    I would give a thought to getting a comp crankcase oil sample from each and every comp and an Acid Test Kit also.

    Also noticed that it look like water/condensation/moisture got into the terminals and possibly created a problem with this unit as the connections look burnt.

    That is correct, according to copeland, 225*F is the MAX MAX MAX discharge temp on the discharge line.

    This is the model.

    LACA-032E-TAC-800

    Looks similar but I don't think the models similar, it's quite large.
