Why the transformer discussion? The transformer is way out in left field. It has nothing to do with the problem at hand. The transformer does not see any turn-on surge. It is isolated from the ac circuit.
If the manufacturer is still using the same thermistor then there are two possibilities (operator error is not one of them):
1. they haven't found the problem yet.
2. you got a defective converter.
Perhaps the soft-start is not functional or the pwm controller chip is turning on when the cap bank voltage is still too low.
