The wire coming from the contactor goes on C. The wire coming from the compressor goes on herm. Of course fan goes to the fan.

ty for your help i wonder if u could help me again. i came home from work one day and my ac had quit working and it was buzzing and the fan wasnt running. i have replaced the capacitor and the contact relay everything seems to be working properly but the ac isnt cooling. i have cleaned my coils too. this is a split system so i not sre what else i should check next. is there a way i can check to see if it low on freon or should i call a tech out for that

Buzzing is the contactor pulled in but no high voltage present. Check the breaker first. If blows again right away then it's cheaper to call a tech out then buying meters and guages.
