Actually, it looks like you already have more loop cuts than needed. Also the topology across the front of the refrigerator is not flowing well vertically. I’m just a noob who’s come to ask another question, so take my suggestions FWIW
What are those two circles doing? Are they separate objects? If they’re integral to the front door, their topology might be integrated as well.
I think one of the main reason of the problem is that the base topology is not good for the rounded beveling used, i mean this :
Those edges that are too close from the boundaries of the model (that you’ll use a bevel on) are going to generate lots of problem regarding the smoothing of the surface :
Instead you should start with that kind of topology :
That has enough space between the boundary edges and the ones inside so you can get the beveling doing it jobs without the generated edges getting too close and creating sharp problems in a smooth surface
