It probably has something shorted to ground or the compressor or motors are stuck causing a high amperage problem. The breaker is probably fine but it also could be weak but normally its the compressor or a component has faulted to the compressor. If the unit immediately trips breaker its probably shorted to ground. If the unit struggles to start and a few seconds pass before it trips then it may be a component fault.

I found this I hope it helps.
