How many of you have seen multiple copeland scroll issues with discharge check valves failing to holdback during off cycle causing on/off cycling on low pressure. This kills contactors and start relays, caps etc.. I've had multiple compressors on different units w/ the same problem. Low temp 404a application. Units are 18-24 months old and out of warranty, customer is ticked that unit runs fine just kills wiring and components when load is satisfied. ZF15K4E model. Not a cheap compressor to replace.
I advise my customers of the high future replacement cost of scrolls and sell mostly semi-hermetic due to the ready access and rebuild cost.
