when your ac in running in the house should the fan on the air unit outside always be running also?
Answers:
It had better be or else you are going to have problems.
The fan not turning is going to cause the bearings to burn out, resulting in a non funtional center air unit and it may even cause a fire.
Get the unit checked right away.

No. Your inside fan circulates the air inside the house if it is set on "on" and will go on and off if set on "auto". The outside fan, the one on the compressor, will cycle on and off as the compressor cycles. Incidentally if you have the inside fan on "auto" it will cycle with the compressor.

yes, it should this keeps the unit cool so that it can blow cold air inside.
if you have the tstat on a/c and the fan on auto, yes.... if you just have the indoor unit on fan, no..... if the a/c is running, and the outdoor fan is not, it will cause the compressor(in the outdoor unit) which pumps the freon thru the lines and into the fancoil inside... to burn up. a new compressor costs a lot more than a fan motor and start capacitor will!
better question is if the compressor outside is running, should the fan[condenser fan] be running? YES it's function is to remove heat from the condenserwhich removes heat from inside the house.as other have commented, the fan inside depends on the setting on the t'stat [on/off/auto] might have accidently been switch to on and is always running when the condenser fan is off.
"coke freak" has the best answer, but there is an exception. Gas heaters (maybe electric, too?) in the US have a thermal sensor in the heat plenum that keeps the inside fan running for a while (but not forever) even after the flames are out. This is for two reasons: 1. move the heat out of the unit and into the house for best efficiency, 2. prevent excess heat in the plenum ("heat soak") from contributing to a unit failure that can lead to a house fire.
I believe that some A/C models have a similar feature (keep running the inside fan after the compressor is off) for the same reason as #1 above: get the cold air into the house. If thermostat fan control is on "auto" and your inside fan continues to run for a short while (a few minutes) after the outside fan & compressor (must be both!) stop, then I suspect you have one of those special systems (and everything is ok).
Normally, if your A/C is putting cold air out of the registers the fan on the outside unit should be turning. The air-mover inside the house (furnace or air handler) does not have a fan - it has a blower which consists of a motor, squirrel cage, and sheet metal housing. If the equipment inside is running and the fan is turning outside, and cold air is coming out of the registers with some force, then it's a good indication that things are operating normally.
Yes
