Question

Air Handler Works/Outside Unit Does Not


I live in the Ocoee, Fl. area(nearby Orlando) and I have a Carrier/Puron Refrigerant Air Condition Unit (Model# 38EYG048301) and it stopped working several days ago. The Air Handler (Model# FK4DNB006000AAAA, Mfg. Carrier) works fine. In about 10-15 minute intervals I hear a sound coming from the unit as though its about to turn on but I never see the fan turn and the sound eventually stops. On a another forum, an expert asked me to turn the outside fan manually, I did and it started turning and the unit began to process cold air. However, when it turns off via the Thermostat control and then turns back on, the fan doesn't work and I have to manually turn the fan again. The experts on the forum suggested that I have a bad capacitor. Does anyone on this forum agree or do you have another suggestion? I have 2 photos enclosed to show what the condenser's control panel looks like with the run capacitor and the hard start capacitor for the compressor. The Run/Start Capacitor is a GE Model# 97F9816(60/5 MFD, 370VAC,+/-6% tolerance). Do I need to replace both the run/start capacitor(silver capacitor on the left of the photo) and the compressor hard start capacitor(power boost capacitor on the right of the run/start cap in photo)? Please advise?

The picture removes all doubt, you can see the way the top of the capacitor is domed upward at wiring connections. This definitely indicates a bad capacitor. Don't know if you have a local Grainger Store but they usually stock most capacitors.

Thanks "Skip". All the expert counsel I've received points to the Run Capacitor. I will let you know how it goes after I install it. Again thanks

BTW: I did order the capacitor through Grainger and I will pick it up tomorrow at our local store in Orlando. Thanks

I have the exact same condensing unit as g8tkeeper. My problem is a bit different. The compressor and fan both start at the same time and I do feel the cold air as the outside unit is running. However, after about 2 minutes, the fan and the compressor shut off then turn back on after about 5 minutes. I have the exact same capacitor as g8tkeeper and there are no visible bulges like he had demonstrated in his pictures. The fan runs fine, there are no noises, it doesn't wobble or anything. Do you think I should replace the both items as stated by g8tkeeper? Any other suggestions to trouble-shoot this problem will be very helpful.

Sorry I didn't post the outcome of my troubleshooting. It turned out to be the blue canister/filter (i'm guessing it's a filter) that is soldered to a line. This happened to be clogged. It was causing some kind of flow restriction. Anyway, it was replaced and it's running fine.

Late last night the fan outside the A/C condensing unit stopped running. I checked the capacitor and it has a similar bulge as illustrated in this post. I also may need to replace the fan motor. My A/C tech told me last year that the fan motor was pulling too many amps, I believe and eventually it would need to be replaced. Going to go out and buy the replacement capacitor now. Hopefully this will get my A/C going1 It's going to be a hot one here in Orlando, Fl!
