Hi,
I have a Lennox 10ACC−036−230 A/C unit and the compressor fan won't start on its own, but if you spin it a few time it will.
This unit which is about 8-9 years old initially had a dual capacitor, but a few years ago a technician replaced it with two separate run capacitors (I think because he did not have a dual w/him). Last year I noticed that the fan motor would run for about 20 mins and cut off, so after getting advice from kok328, I replaced it's capacitor (7.5mfd 440vac) and it worked fine for almost 1 year to the day.
The other day, I noticed that the compressor would kick on the but the fan motor would just hum while the fan would seem to struggle to move. If I helped the fan motor out by spinning it in the proper direction after a few times it would run on its own. So I replaced the capacitor again, it worked great for 24 hrs. It started up fine on its own during the day and night, but now the fan motor won't start again on its own, but the compressor kicks on. Now about 48hrs since I replaced the fan motor run capacitor it will turn on only if I help it, like a jump start spin.
I have attached a picture of the 2 capacitor if that helps. The capacitor on the left is for the compressor (50mfd) & the capacitor on the right is for the fan (7.5mfd 440vac). It may be hard to see but the white wire connects the two.
Should I replace the two run capacitors with a new dual capacitor? The capacitor for the compressor is 3 years old now. Or do you think it need a new fan motor?

Thanks in advance for your assistance.
