Went from a single capacitor to a dual Capacitor and the fan is now going in and out.

Tried to fix my own AC. Had a technician come out and tell me my contactor and capacitor needed to be replaced. He wanted to charge me $500 to do bo th so decided to try it myself. I bought both items and changed out the co ntactor easily enough just by going wire to wire. However, the AC unit was using a single capacitor with a start capacitor and I switched to a dual ca pacitor. Figured out where the wires were supposed to go (I hope) turned p ower back on and the fan would run but then after about ten seconds it soun ded like it would switch off and then start back up, then switch off, and t hen start back up, kept repeating the pattern.
Any ideas?

Should clarify, it would run ten seconds then switch off and start immediat ely back up, then ten more seconds later would do the same thing

The capacitor needs to be the same value as the original.
Just for example if the original was 10 mfd
then if your replacement was 10mfd /10 mfd you'd use only one of them
or if 5mfd/ 5 mfd then the two would need to be wired in parallel.
The values do not necessarily have to be exact but should be within a couple of mfd

They are exactly the same. Double checked it after the fan acted the way it did.

Then the guy must have mis-diagnosed things.
Sorry I can't give better help...but is this switching on and off, the same problem you had prior to changing to capacitor and contactor?

I didn't have the problem before. He said the capacitor and the contactor were about to go out and recommended replacing them.

Disregard...I let it run a bit longer and it started to run normal again. Seems fine now.

Glad it's working but I am sure the guy was a rip off.
A capacitor can be checked for value and unless the terminals are burned there is no way one can tell if it's about to go.
As to the contactor, if the contacts were badly burned it probably was not a bad idea to replace but normally it would not be replaced unless the coil opened.

Last year my heat pump went out in the summer. Called the repair man and was told it would be about $ 90 to come out. He said it was the capacitor. I thought it might be $ 50, but his company has a fixed rate of about $ 350 to replace one.
Felt ripped off on that, but he did a coil cleaning for less than $ 100 and a good checkout. I learned a lot from that and got a capacitor and contactor off ebay for about $ 40 in case either may go out again. Most would have felt ripped off, but I felt like I got a good education on the system while he was here. I do have some gauges and a tank of refregrent that I used to charge a sysem in another house I lived in. Had to buy the refrigerant but aquired the gauges and hoses for free. This man did seem to really know what he was doing.

If the price seems a bit high but the work is done right , it is not a rip off.
In the situation with the OP though, it might have been.
Then there is this (which I posted maybe a year ago):
While fiddling with a leaky toilet my wife told me a dozen times to "call a plumber!" Since I really did not want to fool with it anyway I took her advice and thought, "well there goes $500."
Nope, he quoted me $2000! I'm serious!
Fortunately the service call just to come out was just $64 and he did a thorough inspection of the pipes.
I went to Home Depot, spent $85 for a new toilet which works just fine.
It took me an hour to put it in.

Did he have his finger on the trigger while he pointed that toilet at your head, and reached for your wallet?

Two grand sounds a bit extreme, for a toilet. Even installed. Did it at least have ATR?
