When I had to replace my 41 year old GE oven, I was concerned.  I had used the oven alot and had zero problems!!  The only problem with the oven was one of the hinges broke.  We searched for another hinge, but had no luck!!  Sooooo, I looked for another GE.  The new oven had to be installed into a brick wall.  Our contractor did an outstanding job with the installation.  The only problem installing the new oven was we needed a "trim kit."  GE does not have one for the oven, soooo our contractor made one for us.  GE does have a trim kit for microwaves (which we had to get for our GE microwave).  I have used the new oven for everything from cookies, roasts, and broiling.  Very pleased with the new oven.  Hopefully, it will last 41 years!!
