Older five ton unit. Working fine yesterday mid morning. Returned late last night and it was 86° inside the house with the inside fan blowing. Outside unit only buzzes/hums. Changed the capacitor with no change to buzzing/humming.
Fan motor, compressor or something else?
TIA

Do you know if the compressor is starting?
Do you have fuses on the panel outside?
You need to check voltages on the contactor/relay. Power in? Power out?

Thanks, all!
Checked the wrong breaker box inside.
(Older house with two main panels.)
Compressor and outside unit fired up after I reset the tripped breaker.
