Not sure how many evaps are off the pack, but if the suction valve was closing on defrost, unless the coolers are all defrosting at same time then room temps must be all over the place?
From a super heat perspective, the suction transducer would be S2 with S1 being a probe strapped after the EEV, but am open to correction on that as it's a good while since i worked on danfoss aKV's.

Have there been many compressor failures?
