AC Down Troubleshooting For Air Conditioner No Cool Video

Got an AC down. Points look a little worn on the contactor. Capacitor looks a little tired but nothings running. I’m going to go ahead and pull my disconnect and then come over here and I’ll discharge the capacitor. There we go. Let’s see. The compressor’s pretty hot. I’m thinking maybe the condenser fan motor stopped running. Don’t see any burned wires. Everything looks okay in there.

I’m going to loosen up this one. It’s about 116 today, humid. [inaudible: 01:29]. This is going to be a stubborn one, too. That’s not good; fan motor didn’t start up. There we go, see how I can kick-start it with my pen? The fan capacitor’s down; we’re going to grab another fan capacitor and change it out, but at least it’ll get the people cooled down for a little bit. It’s pretty hot.

This unit; had a couple things going on. The starter capacitor is bad, and also, this should be secured a little bit better so I am going to show you how to do that. There are a couple different ways, but I’ll show you one method. I’m going to go ahead and pull my disconnect, and then come over and we’ll discharge the capacitor. There we go. Then we’ll discharge this little capacitor. I just got my screwdriver in there to bridge the leads. Finished taking this off, then we’re going to slip our leads off good old capacitor. There we go.

What we’re going to do is we’re going to make a place to mount our new capacitor. I’ve got me new capacitor, and we’re going to hook this up. We really don’t want this just hanging free. Sometimes you do what you’ve got to do but it’s a little bit better if you can mount this. What I have is some plumber’s strap and some self-tapping screws. What we can do is pick this up a little bit better, make this a little bit safer and easier for somebody in the future. Just the main thing is you want to make sure that there is nothing behind here that this is poking into. I’ve worked on these units a lot, on this particular model, there is nothing behind here. On other models, you’re going to have to check and verify that there’s nothing back there so that you don’t end up poking into some refrigerant tubing or anything like that. That’s in.

It looks like that’s going to be a little too tight on that hole, so I’m going to go with this hole. It’s probably better to go with a little bit stronger drill than that, but that’ll work. If we ever have to replace it again, we can just slip it out and slip in a new one. We’re good to go. I’m going to go ahead and plug my disconnect back in and make sure everything starts up okay. Our fan motor blades kicked on right away. [inaudible: 04:56] start capacitor. Obviously if the motor didn’t start, then the motor would be bad. The line is nice and cold. That’s how to make the unit a little bit safer.
