Has anyone ever work on these Samsung / quiteside http://www.quietside.com/Quietside/i...d=35&Itemid=68

unit AP500PF I'm working on 4 of these 3 of them not working at all on the motor protector module where it reads s1 and s2 for the compressor sensor that it is built internal when I ohm it out it should read 1500 min high 7500
instead I get out the three 45 on 1st O.L on 2nd and 3rd one got 4000 these reading was taken @ the compressor on the S1 and S2 legs wires off is it safe to say that the comperssor is junk on #1 and #2 since there noway to fix it these 3 units been off for 2 weeks any thoughts?
