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?
