I am trying to replace an OTR microwave since the previous (quite old) one stopped working. While the space is the standard 30" wide, to the left of the opening is essentially a wall, and while I tried to put in a couple of replacements, both of the doors failed to open fully because they hit the wall. Sadly moving the cabinets is not an option, and the best I can come up with is trying to plane off the 1/4" lip on the cabinet and move the microwave over in the hope that gives enough room for the door to open.
A nicer option would be a door that has a hinge that is inset but I haven't been able to find anything so far beyond a low profile option that just feels too short.
EDIT - Per one of the answers below, I had taken a look at Left-to-Right opening doors, but unfortunately couldn't find any either. The best so far has been a low profile option from Whirlpool
This is the replacement microwave that doesn't open
This is the old microwave door open
This is the new microwave door open
As you can (hopefully) see, the fact the door doesn't open flush is the root of the problem.
Finally, here's a picture under the microwave next to the right hand cabinet
Regarding @PhilippNagel's answer below, this is my fallback option, although I don't like it visually or price-wise (but at this point beggars can't be choosers)
