Having a repeated problem with my A/C unit outside. I get a hum but the fan doesn't spin.

It seems this was the problem I had a few years back and replaced the motor (new one is a Fasco D7909) and all was great in the world.

Couple quick things I've checked:

Contactor is not pulling in when turned on. When I manually pushing it in I get the humming noise and no fan.

Capacitor looks fine, no bulges etc.

I spun the fan blades manually and they move freely.

If this is a bad motor again what would cause me to have to replace the motor on an A/C unit this is only 10.5 years old??

**Update**

Ok I took the capacitor off and it was definitely bad. Bulge in the back I couldn't see before. Just got back and replaced it.

A/C is up and running like a champ!

BUT

In the house the cool air is coming in but not as hard as it should be. What should I look for at the blower? The house filter is good, replaced it about 2 weeks ago.

 

check the evap coil to see if it is plugged up or if the blower wheel is dirty.

 

I have never really looked at the blower before. Is it difficult to check the evap coil?

 

it can be difficult..... Most homeowners have pros clean them when necessary, but dont know if it needs cleaned..............

 

I went up in the attic to look at the evap coil but I didn't see where to actually get to them. The few places I thought to look the seams are sealed with metal tape and a bondo type material. I'll head up then in a few and take a quick picture and post the setup.

 

Ok nevermind have to learn how to post pictures first lol
