I have this unit its a Bryant very old. The contactor was not pulling in for the comp and fan. I have 24v at the coil of the contactor but it does nothing. I ohm it out and its good push it in and comp and fan runs. Its the original contactor so I just replace it anyway. My next thought is the transformer Im thinking I may not have enought VA for everything in the system. It has a impendance relay(its wired in with the comp over load protection), comp contactor, and the fan relay. Would it uses a 40VA or more??
