Rheem JEC L-04 error code

I have a Rheem 048JEC Dual Compressor Comfort Control Condensing unit. Last year I was getting an L-04 Locked Rotor error. Worried about the worst I called a repair person in who replaced the Run Capacitor for a $300 service bill. He did come the same day and got me working again
No more error codes last year. This year the same error always on Compressor A. The unit could be reset and then would work fine for a day or a week only to repeat the issue. I replaced the run capacitor again. No change still occurring randomly also replaced the start capacitor (not the relay). Still no change. Can go a week or a day and recur.
Anything else I can easily check or change?
Thanks you,
