Keeps tripping the circuit breaker

I have a swamp cooler for my business location, 110 volt motor. Whenever I turn on the swamp cooler, the circuit breaker is tripped 3 or 4 seconds later. The cooler used to be working fine before but I just found out that the store was not as cool as before.
What seems to be the problem? Any advice would be appreciated. Thanks in advance. Andy

Does the motor turn during those 3 or 4 seconds, or is it frozen? Can you turn the motor by hand? Perhaps the motor is shot.

I can't see the motor because the unit is up on the roof but I can hear the motor running for that period of time and shuts off. I suspect that the ventilating fan might be binding?

If the vent fan is operating on the same circuit as the cooler motor & it is starting to seize then that may be the problem.Do you have access to an amp meter? If so I would check both motors amp draw with what is stamped on each of their nameplates. If there is no nameplate for each motor there should be one that give the combined amp draw for both.
