The Hotpoint REM25SJ is a countertop microwave oven. You could replace it with something like this GE JES1072SHSS or the LG LMC0975ST which is a bit larger.

It may list as a counter top, but we installed it under the cabinet. These two options that you’ve suggested, can the be mounted under the cabinet as well?

I have enough space for bread and stuff. If it’s on the counter, I have no space. So, again, I was wondering if you knew of any under the cabinet microwave ovens or a counter top brand that could be bolted under the cabinet? Thanks

Oh, you wrote "under the counter" when you meant "under cabinet". The GE JXA019K allows several GE microwave ovens to hang under a cabinet including the GE JEM3072SHSS and GE Profile PEM31SFSS. See the installation instructions for a list of models.

Lol. Sorry about that

Just wanted to thank you for the information! I ordered the GE jem3072shss and the mounting kit today.
