    Ive had Carrier send out a Compressor that was suppose to be low temp, was marked as low temp and had medium temp valve plates on it. Ive heard of others having this experience so be mindful of that. Very aggravating.

    How do you know it had the wrong plates? Did you take the heads off a brand new compressor? Why?

    there is always oil in the cylinders

    if you had too much oil you would have a broken connecting rod and no oil pressure!!!!!

    could you post

    suction
    discharge
    net oil pressure
    compressor superheat
    subcooling
    discharge superheat
    crank case temp
    cylinder head temperature all 3 heads
    and under cylinder temperature?

    thanks

    Because the heads where getting way to hot so we took them off to look at the valves and seeing how we rebuild compressors, we knew that the valves were wrong. Simple as that.

    you could simply check the compression ratio?

    Of course there will be some oil present but Eddie said " there is a lot of oil in the cyllnders" That's not normal. That indicates foaming and flooding,

    FYI,
    One of the most agrivating problems we had on a 06E/suction cut-off on a chiller was an intermittant compressor tripping. We finally just had to wait until the breaker tripped [which was due to rapidly climbing amperage]. Suspecting a bad compressor, we spun it over with the heads off and found no slack in the rods/wristpins. We then realized however unlikely it seemed, that the problem was in the valve plates. We found a chipped discharge valve that was filling the cylinder with high pressure gas on the downstroke. When the suction cut-off unloader sealed off the suction to the cylinder, then the upstroke filled with high pressure gas would overload those two cylinders since the high pressure gas was almost impossible to compress and it could not travel back out the suction like it was doing when the cylinders were loaded [the suction cut-off was open].
    I shared this with Leon L at Carrier who happened to be at the jobsite with some machine code software issues and he was supprised that this could happen. I have only seen it a couple of times since.....
