Why do you need to replace the fridge? No one cares one bit if the appliances match. The idea of matching appliances comes from tract home developers who buy appliances by the shipload so they match and can be installed identically in all their thousands of homes. If your fridge is not broken, leave it alone. It won’t be easy to find a fridge in that exact cutout size and which allows the fridge door to open against the door on the left.

If your current fridge is broken, you must find another fridge with those same dimensions or smaller, but also in a size where the fridge doors can open without being blocked by the adjacent door and cabinet. The brand name and whether it’s a french door style take backseat to the size and cutout priority.

She can pull the unit forward temporarily if/when wider door-swing is needed on the left side, then push it back when done.

I too don't care if my appliances are the same brand. I buy what is most functional and/or has the features I most need. I don't know if this is your issue or if it's what you are wondering about, but Bosch has an option for a fridge with recessed handle openings rather than handles that stick out. I think I am getting a Café range and a Bosch fridge (along with an ASKO dishwasher).

Does the angled side wall (pantry door?) get in your way when you open the current fridge? I would think that the Cafe option would not allow you to open the left side door very wide. I know you want French door but a single top door would solve that for you.

I have to say that while dadoes suggestion is simple, I wouldn't be happy to be moving my appliance each time I wanted to get part of it open!
