      Hello everyone,

      Recently I had a Carrier 30RBF12064RLMV6C has tripped out on Co.B1 , Co.B2 , Co.B3 communication loss with compressor SPM with the last 2 weeks. Ive checked all the wiring. Is there something that i have missed ?

      Is there a cheat sheet for troubleshooting these issues ?
