I own a GE space saver microwave oven, model # JVM1631BB002. I started up my microwave this morning and after a couple of seconds it stopped working. The control panel is working fine, but when you try to re-enter a cooking time and press start nothing happens. I checked the house fuse and reset it and tried the microwave again. The microwave turned on this time after entering a cook time, but shut down a few seconds later. Any advice as to what could be causing the microwave to blow the house fuse continually would be appreciated.
