the home we live in is a 80x16 mobile home (manufacturered home), the microwave was installed by Marlette Homes in Lewistown, Pa.  There is only a 1 yr. warranty.  We are fighting with Marlette over a broken kitchen window that is covered for 1 yr. and defective upgraded carpeting with a 5 yr. warranty.  They are rude to us, said they don't stand behind their product, ie. Marlette Homes, and then hung up on us.  We contacted a GE repair center, it will cost us more than what a new one would cost us.  It is built in and we have no idea how to remove it to replace it.  Consumer reports say the model we have has a very low approval rate.
