Hi Guys

Is anyone experiencing reversing valve failures on units using 410a. We have quite a few that have stuck in the cooling position, within a year of installation. Proper installation and evacuation procedures are strictly followed, so that can be ruled out.
When we cut the old valves apart, it seems as though no oil is traveling with the refrigerant, as compared to a valve off an old decommissioned R 22 system. This problem isn't isolated to one manufacturer and other contrac`tors in my area are experiencing the same problem. Tried to get warranty but that is next to impossible these days, by the time you push through the manufacturers red tape. We install a lot of Byant and York.
Any experinces or suggestions?

Thanks
