how to hook up capacitor

tazland

i just bought a new capacitor for my outside ac unit. it has 3 wires red, tan, and brown the new capacitor has fan, therm, and c on it the old one had no markings. how do i hook it up

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.
