Ac condenser fan not working

30-5uf 370v capacitor, 27uf and 4.97uf tested. Compressor comes on but condensor fan does not. 1.5a on wiring to fan motor. Anything else I can do to confirm the motor is the problem. Tested 240v across both sides of contactor.

Will the fan start if you manually spin it?

Checking the capacitance doesn't prove the fan cap is OK. Most cap meters use a low voltage - the caps can leak at full line voltage.

I checked if there was resistance with the fan blades but did not try spinning to start. not much resistance
