recently fitted a new contactor on a mitsi mr slim pu-p4yga on r407c, faulted by another engineer.put unit in test mode and contactor erratically pull in and out showing uf fault code which is compressor current overload.I checked windings,3 phase balance.Compressor to earth all ok,compressor starting amps 15, running amps between 4-5 but does anyone no if they are the correct amps for that model ?

Many thanks
