Hard Start Kit Air Conditioner Install Video

Kung Fu Maintenance demonstrates how to install a hard start kit.

OK I got a call for no AC last night. Everything is running right now. The line is flashing nice and chilly. Everything is nice and cold but my suspicion is that. This is a new unit and out here it just seems that all of them need a hard start kit in order to start and I bet you if I check underneath here I am going to find that it does not have a hard start kit. And that that’s what is causing the compressor to sit there and hum and not start. Sometimes it will start and sometimes it won’t start and it will take awhile. I’m pretty sure that is what is going on here. So just going to open it up and take a peek. Yep, no hard start kit.

So I’ll get a hard start kit on this and that will keep it running. It’s running now like I said nice and chilly but my suspicion is when it starts up it is having a hard time to start up. And the hard start kits going to go right here on the red purple line and on the yellow line. That’s our common and our herm line. C is for the red and purple and than herm is for the yellow. The brown one is for the fan. I’ll go get a hard start kit and get this going. OK so now I am up here. Ready to pull the disconnect. The unit actually turned off. As you can see, well you can’t see. lol. That contactor has sucked back out. It has got a little dust cover on it right here.

I am going to go ahead and pull the disconnect so I don’t get. So it doesn’t kick on on me while I am working on the unit. Than what we need to do is discharge the capacitor. Beacuse a capacitor holds a charge in it even after the power is disconnected. The way we do that is just bridging the leads to the capacitor. Than here is our hard start kit and with this we are just putting it one to the herm and one lead to the common. Like so and we’re all set there. Now we just need to find a place to hang this where it’s not going to get in our way. There we go. Yeah. That will work. Put our cover back on. OK. And we will put all our screws back in. Another one on the side over here.

OK we’re all set there. Now the unit will just fire up and won’t have any trouble when it goes to start. Doesn’t just sit there and hum and not start overheat. Plug my disconnect back in. To insert the cover here this just rotates over and passes through. Has the option of putting a padlock there. Some areas need that. Need both hands here. There we go. All set there. Good to go.
