mitsubishi mr slim restriction
well first let me say that Im not sure if this the right place to post my question, I've posted a couple of questions on this site before, but its been awhile so..I often read on this site whenever I get spare time, but rarely post anything. anyways
Question: anyone ever come across a mitsub mr. slim with a restriction?
if so how/ what did you do to repair?
a little info; Im getting error code P8-"abnormality in outdoor unit" 210 hi side /60 true suction + only 65psi @ transphase port, (the access @the service valve) I was told by the mitsub. tech support guy I should have about 100psi there! superheat of about 39, supply air 66 return of 75
Any help sugestions will be greatly appreaciated, thanks

They are notorious for liquid line restrictions, there is a small bulb with a strainer inside in the liquid line before the metering device, cut it it and replace it with a regular dryer.
