When a condenser fan motor grounds out, it can cause a short circuit and trip a circuit breaker to shut off the unit as a safety measure. If the fan motor keeps running as the current is only going to ground, it can cause overheating and damage to the motor. Running a little faster because the amperage draw will increase is not a likely scenario. The evaporator does not have a direct connection to the condenser fan motor, so it cannot be affected by a grounding issue in the fan motor.
