As long as you do not leave it in place beyond your troubleshooting, a standard breaker could be put in the panel in place of the AFCI. You might then be able to hear, see, or smell signs of heat or arcing. Blinking lights on the circuit would give additional clues.

Some appliance models have been known to trip an AFCI by their sensitivity to either arcing in flat-screen TVs, vacuums, other appliances with motors or to ground-faults in treadmill, fluorescent lights. If the nuisance tripping stops, then the old arc-fault breaker was probably defective. If the arc-fault breaker still trips, the electrician then needs to track down the cause by going into each switch, receptacle and light box to look for a wiring problem. Notifying the electrician that this is happening is the best idea, if the breaker is always tripping when you use the vacuum or similar appliance then there might be another issue for the electrician to look into.

So some tripping is a small price to pay for the increase in safety and reduction in potential fire risk. It is important to us that everyone works together to create the best possible experience.
