Question

Air conditioner is humming but not turning on, no cold air is blowing but the furnace fan is blowing

Answer 1

Have you reset your breakers?

Answer 2

that happened to me and an AC company came out and said I needed to replace the whole thing for around 3000 bucks. My dad came over and replaced a 50 dollar part and it worked fine. I wish i remembered what the part was called.

Answer 3

First check the condenser breakers

check the disconnect box outside by the unit for fuses

Put your ear on the outside unit unit  and you hear a hum you have 24v, more than likely a power supply problem.

Worn contactor

shorted or open capacitor

broken low volt wire near the outside unit

open time delay in the condensing unit

head pressure switch

over flow switch on drain line

Bad circuit breaker

Many things could be wrong, if you are not sure please call somebody who is trained!

Answer 4

well you should try checking the filter first if that doesn't work then you should try calling a repair man and if all else fails get a new furnace!
